Questions about a square kicker
|
Bronze Member Username: Dloco486Post Number: 75 Registered: Apr-11 | i just got a square kicker in a trade. On the magnet it says SL7 but it dont say on the front so im not sure if its an L7 or not. and it doesnt say rated power on it so i was wandering how much power i should run to it and if i should run it sealed or ported? |
|
Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 25 Registered: Nov-10 | give it 1000wrms and put in a 3.5 ish cu ft ported box tuned to 33 hz or so. if on the magnet it says sl7 its an l7 model, im pretty sure. |

Silver Member Username: MakinblakMonroe/Monticello, La/Ar Post Number: 634 Registered: Oct-10 | What size is the sub? Describe how the magnet looks and how the cone looks. And what does the cone say? Should either say L5 or L7 |

|
Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 26 Registered: Nov-10 | yeah dont listen to me, i dont know anything, thats what i would do if it was me, i would blow that sheezy up lol or get big bass!!!!! |
|
Bronze Member Username: Dloco486Post Number: 76 Registered: Apr-11 | how do i post pics on here and ill get a couple up. right now i have it bridged on an amp @ 8 ohms because if i bridge it @ 2 ohms i think it will kill the amp. dont know how much power its getting but my amp barely moves it. the amp is rated @300x2 @ 4ohms 500x2 @2 ohms. |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1061 Registered: Jun-06 | Im not sure what version of the L7 you may have, but those Subwoofers can handle 750-1000 Watts RMS depending on the model. If your actually running the amplifier at 8Ohms, I can't even manage what little amount of Watts RMS your sending so im not surprised that it is hardly moving. Also, in order to post pictures, you will need to upload your pictures on photobucket. Then, you will click on the "Link" option above and paste the URL of your picture and click "OK". |

|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1062 Registered: Jun-06 | That's a Kicker Subwoofer alright. A Kicker S12L74 to be exact. It's a DVC 4Ohm Subwoofer that is rated for 750 Watt RMS. What ever amplifier your using is no where closing to powering it all the way. |
|
Bronze Member Username: Dloco486Post Number: 79 Registered: Apr-11 | yea i traded my power acoustic 6x9 for it cuz they wouldnt fit in my talon. would i get more power to it if i ran it off 1 channel @ 2 ohms cuz i cant bridge it at 2 or can i wire each coil indipendently to each channel. is it an l7 |
|
Bronze Member Username: Dloco486Post Number: 80 Registered: Apr-11 | thanks joe s can i wire each voice coil seperately to each channel or do they have to be wired together |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1063 Registered: Jun-06 | What amplifier are you using D Loco? |

|
Bronze Member Username: Dloco486Post Number: 82 Registered: Apr-11 | the amp is a LEGACY LA2970SL |
|
Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 30 Registered: Nov-10 | i heard you shouldnt put individual coils into separate channels only individual coils into separate amps, but dont quote me on it. |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1064 Registered: Jun-06 | That amplifiers specs goes as followed: 2 x 300 Watts RMS at 4 Ohms 2 x 500 Watts MAX at 2 Ohms 2000 Watts Bridged Power at 4 Ohms I honesty have never seen such BS specs for an amplifier ever in my life. Even the service manual says the same specs. There is no way possible this amplifier puts out this much Watts... Since you have the DVC 4 Ohm version, I would suggest wiring each VC on it's own channel to keep it at a 4 Ohm Load. It's the best way to get the most of what ever power is coming off that amplifier. However, I woudl suggest looking into a more power amplifier if you intend to use this subwoofer. |

Gold Member Username: Th3pwn3rI compensate... Post Number: 9779 Registered: Jul-06 | That sub is ooooold. |
|
Bronze Member Username: Dloco486Post Number: 83 Registered: Apr-11 | i plan on buying a better amp when i sell my 15's. hooking up each coil that way wont damage the sub will it? |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1067 Registered: Jun-06 | Each VC can handle 375 Watts RMS. That amplifier "supposidly" puts out 300 Watts RMS per channel at 4 Ohms. If anything, the Amplifier will get damaged before the Subwoofer. |
|
Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 31 Registered: Nov-10 | what happens if a song has bass in the left channel not at the same time as the right channel like surround songs if that makes sense it wont affect the voice coils |
|
Gold Member Username: Th3pwn3rI compensate... Post Number: 9785 Registered: Jul-06 | Lol @ that Legacy amp. Also, if you have a mono amplifier it's not going to matter. |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1068 Registered: Jun-06 | The overall issue eddie is that is not the right type of amplifier you need to power that Subwoofer. I was just letting you know the best way you could use it at this time. I would suggest looking into this amplifier here if you plan on using it: http://www.audioque.com/AQ1200D-Amplifier_p_30.html |
|
Bronze Member Username: Dloco486Post Number: 85 Registered: Apr-11 | same question eddie asked. it wont effect them if there is bass coming from 1 channel and not the other. on songs like that |
|
Bronze Member Username: Dloco486Post Number: 86 Registered: Apr-11 | i dont want to damage it before i get the amp for it |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1069 Registered: Jun-06 | Then don't use it. Wait until you have the right equipment. |

Silver Member Username: AlonzoubPost Number: 177 Registered: Apr-10 | That Legacy amp has two 15 amp fuses in the pictures. Being a low budget class AB amp I would not expect anything above 60% efficiency. That being the case, I would say this amp probably starts clipping around ~200 watts RMS in 4-ohm bridged mode. Which means at 8-ohms you are probably gonna get no more than 100 watts RMS on a good day. I will vouch for the AQ1200D, although I am not a fan of their recent price changes. They bumped the AQ1200D up to $269. For $30 more you can get one of crescendos new Bass Clef Series amps, the BC2000 which benches somewhere around 1100-1200 watts @ 2-ohms. Might be a bit overkill but for $30 I would probably pay for the headroom. |
|
Bronze Member Username: Dloco486Post Number: 88 Registered: Apr-11 | my legacy amp has 2 20 amp fuses which i found the ratings hard to belive cuz my 200 watt fausgate has a 30 amp fuse lol. i just posted my 15's on craigslist so hopefully i get a buyer. but i need a good capable amp for less than 200$ |
|
Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 34 Registered: Nov-10 | maybe these http://www.sonicelectronix.com/item_6498_Hifonics-XX-ZEUS-R-B.html http://www.sonicelectronix.com/item_12248_JBL-GTO7001.html http://www.sonicelectronix.com/item_22707_Hifonics-HFi1500D.html http://www.sonicelectronix.com/item_22702_Hifonics-HFi2000D.html i would try and get one of these probably hfi2000d or jbl but think it would underpower slightly my odd rule of thumb is whatever fuses add up to add a zero this gives you watts rms amp will do before popping fuses so take 75 percent of that should give you what ull most likely get outta daily driven hope this helps |

Gold Member Username: Gcs8Atlanta, Ga Post Number: 2059 Registered: Sep-09 | amps*volts=watts*%eff (.8 classD or .6 for A/B)= expected wattage. |
|
Gold Member Username: Th3pwn3rI compensate... Post Number: 9788 Registered: Jul-06 | I was actually going to recommend looking for a Hifonics amp. From what I know the lower models are OVER RATED but it's hard to find a cheaper out that does what it can. I would look around for a used one from a good, reputable seller. |
|
Bronze Member Username: Dloco486Post Number: 89 Registered: Apr-11 | i actually borrowed a sub from my cousin so i was able to bridge them both for a 4 ohm load and it sounds a lot better for now till i can get the right amp. but i was wandering if ild be able to bridge that legacy and my fausgate rf 200.2 together to get a lil more boost? if i can how would i wire them 2gether? |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1074 Registered: Jun-06 | D Loco, what are you doing? lol. What is this "other Subwoofer" that you have hooked up to your Kicker? And what amplifier are you currently using? The Rockford Fosgate Punch 200.2 amplifier specs goes as followed: 100 Watts RMS @ 4 Ohms 200 Watts RMS @ 2 Ohms 400 Watts RMS Bridged @ 4 Ohms If anything, I would just suggest installing this amplifier at 2 Ohms on the Kicker and take off the Legacy amplifier if you REALLY wanted to use it. Once again, I would preffer it if you would wait until you could power the Kicker Subwoofer properly to prevent anything from breaking. |
|
Bronze Member Username: Dloco486Post Number: 92 Registered: Apr-11 | when i looked up the specs for my fausgate amp it said 50 watts x2 @ 4 ohms 100x2 @ 2 ohms and 200 x 1 @ 4 ohms. the other sub is a really oldschool sony explode. way before walmart started selling them. its a dual 4 ohm as well. it's 1 with the metal deal sticking up from the center. |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1075 Registered: Jun-06 | I looked up the user manual and that is what I found for the specs. are you sure it's really a Punch 200.2? |
|
Bronze Member Username: Dloco486Post Number: 95 Registered: Apr-11 | its an oldschool. it has that RF they used to use back in the day.and undery it all the way across it says punch. on the bottom it has the model # (Rockford Fosgate RF2002) |
|
Bronze Member Username: Dloco486Post Number: 96 Registered: Apr-11 | would a kenwood 9104d push that kicker? |
|
Silver Member Username: AlonzoubPost Number: 183 Registered: Apr-10 | Yea it should do the job just fine |
|
Silver Member Username: MakinblakMonroe/Monticello, La/Ar Post Number: 636 Registered: Oct-10 | I can't believe my eyes!! DO NOT run multiple channels to 1 sub. That is the stupidest thing I have ever heard. Good way to blow that sub and prolly take the amp with it. It will also b more distorted and less output cuz the channels will cancel eachother out. Even if both channels receive the same signal, they r never pushing the xact same watts or signal. Wire it parallel to a 2 ohm load and run it from 1 channnel of whatever amp u r using now. U ain't pushin nowhere neer max for the sub, but ffr, I would suggest not giving it more than 500 wrms if u plan to enjoy it for any length of time. Or blow its pisss out and buy better ones. I believe that is what others here r trying to get u to do by running two ch. To 1 sub |
|
Bronze Member Username: Dloco486Post Number: 97 Registered: Apr-11 | i wasnt planning on running 2 channels thats y i borrowed that other sub from my cousin so i could bridge @ 4 ohms. but tomorrow im trading my old subs for the kenwood amp and im goin to give that other sub back to my cousin and just run the l7 for now. |
|
Silver Member Username: MakinblakMonroe/Monticello, La/Ar Post Number: 640 Registered: Oct-10 | What the specs on that kenwood? My only web source is my phone and I ain't doin all that |
|
Bronze Member Username: Dloco486Post Number: 98 Registered: Apr-11 | 1800 watt peak 900 rated @ 2ohm 500 @ 4ohm |
|
Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 42 Registered: Nov-10 | good amp, just adjust gain properly, will beat the crap outta sub, go ported around 33hz |
|
Bronze Member Username: Dloco486Post Number: 99 Registered: Apr-11 | it was a good amp for about 45 mins then it crapped out haha |
|
Silver Member Username: MakinblakMonroe/Monticello, La/Ar Post Number: 642 Registered: Oct-10 | Hahahahahahaha epic |
|
Bronze Member Username: Dloco486Post Number: 100 Registered: Apr-11 | needless 2 say kenwood amps are sh!!!t. plus theres no way that amp did 900 watts constant. 600 maybe. |
|
Gold Member Username: JoebruceCrescendo Audio FTMFW!!!, AA Havoc 15 ... Your Mom FTW!!! Post Number: 3473 Registered: May-04 | Maybe it was user fault? Just sayin considering some of your other posts. |
|
Gold Member Username: JoebruceCrescendo Audio FTMFW!!!, AA Havoc 15 ... Your Mom FTW!!! Post Number: 3474 Registered: May-04 | Wasnt trying to sound like an azzhole. Look first off,never mix subs,never run one sub off 2 different amps. If you are set on running that old beat up Keeker then get a proper enclosure for it and get a decent amp that does 500-1000wrms at 2ohms. Set the gain correctly and thats it. Dont touch the bass boost or anything like that cuz then we will have another "blew my l7 thread" and no one wants that. |
|
Silver Member Username: Dloco486Post Number: 101 Registered: Apr-11 | naw it had good connections gain was up a lil over half way sub was at 2 ohm bass nobb on amp was only at a 1/4 way up it was sounding nice then all of a sudden there was no bass. and the amp wouldnt turn on. fuse under my hood is still clean and good. and my other amps were still working when i hooked them up. so it shoulda been good. plus i dont see an amp with 2 30 amp fuses rating at 900 watts constant |
|
Gold Member Username: JoebruceCrescendo Audio FTMFW!!!, AA Havoc 15 ... Your Mom FTW!!! Post Number: 3475 Registered: May-04 | Well Kenwoods are known to be overrated and not that great in the first place so it could have just been the amp. But the gain should be set to match your head units output,not just set to what sounds good. If I were you I would just find a nice used amp or just buy a new one. What is your budget for an amp? |
|
Silver Member Username: AlonzoubPost Number: 191 Registered: Apr-10 | Setting gain: http://www.thesuicidaleggroll.com/gain.htm All you need is a DMM and you will never blow another amp. Unless its grossly over-rated in the first place... in which case you shouldn't have bought it. |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1079 Registered: Jun-06 | Looks like I got here too late. I have a friend with the same Kenwood amplifier. I was going to say that I could get it bench tested to see the real numbers, but now seeing that it is blown, what's the point? |
|
Silver Member Username: Dloco486Post Number: 102 Registered: Apr-11 | It wasnt blown i hooked up 3 other amps an didnt get power the little washer actually fell out of the fuse holder so the copper pieces that hold the fuse werent staying together tight.the amp is still good thankfull for that i was starting to feel ripped off. the guy i traded was a good dude and was going to give me back my subs if we couldnt get the amp to work.@ joe s if u can still get it bench tested and see what it actually runs at that would be cool ild like to know. |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1083 Registered: Jun-06 | Every amplifier even if it's the same may put out slightly differen't numbers, however I will try and see if my friend is available this weekend to get it bench tested. |
|
Silver Member Username: Dloco486Post Number: 103 Registered: Apr-11 | that would be cool. ild appreciate it. |
|
Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1084 Registered: Jun-06 | Actually, I just noticed something. There are 3 amplifiers by Kenwood that generates the same specs. These 3 amplifiers goes as followed: KAC-9103D KAC-9104D KAC-9105D My friend has the KAC-9103D. Is that the same one you have or is it one of the other two? |
|
Silver Member Username: AlonzoubPost Number: 197 Registered: Apr-10 | The last number in the series is pretty much a version number from what I can see. So ASSUMING Kenwood makes improvements when releasing a new version... the 9104D should make equal to or greater power than the 9103D. Lol... thats how I look at it anyway. |
|
Silver Member Username: Dloco486Post Number: 104 Registered: Apr-11 | it's the 9104d. ive heard they shrunk the newest model and that its not as good as the older ones. but thats only hearsay from one person. does it cost $ to get an amp bench tested or will audio shops do it for free if they think ure goin to buy summin from them. also does anybody know of a decent pair of shallow mount 6x9 i could find on ebay or amazon for $40 or less? |
|
Silver Member Username: Dloco486Post Number: 112 Registered: Apr-11 | is there anything u can put on subs to condition them? if i run this sub sealed how big of a box should i use? currently running ported but listen to a variety of music and there's some it dont sound real good. |
|
Silver Member Username: MakinblakMonroe/Monticello, La/Ar Post Number: 658 Registered: Oct-10 | armorall wipes make it look nice. not sure if it helps it. sealed= anywhere from 1.5 to 4.5 cubes would work for that sub. It just depends on what sound ur looking for and how many WRMS you are sending it. I says go 3 cubes with polly fill stapled inside. |
|
Silver Member Username: Dloco486Post Number: 114 Registered: Apr-11 | is polly fill that pillow stuffing? i'm running round 5 to 600 WRMS. amp says 900 WRMS but is kenwood and over rated. 3 cubes insulated was what i was thinkin just needed someone to confirm it thanx. |
|
Silver Member Username: Dloco486Post Number: 186 Registered: Apr-11 | i'm trying to sell that L7 and that kac 9104d on craigslist how much should i ask for it. subs i know sub looks beat up but performs nice. Amp looks brand new.do yall think i could get 200$ for it. |
