New member Username: BrlntxColunbia, South Carolina United States Post Number: 1 Registered: Apr-08 | I have a 1998 Chevrolet Cavalier... I am going to run 4 Kenwood Subs (12") I also plan on buying new door speakers and new 6x9's. What type of high output alternator should I buy? My old stock alternator went bad on 2 Jensen 10" subs and 1 MTX Thunder 7500 12" sub. Pushed by a 1000 Watt Sony Amp. Do I need a high output alt? Or could I push the 4 Kenwood 12" subs and the components with good Amps without killing my stock alt? Either way will you give me advice as to what I need to buy? |

High output. cuz its prob gonna take more than one amp to run 4 12s and if you run a componant amp thats gonna draw even more power. ho alt and big 3 upgrade should do as far as getting power to where you need run some 0ga wire back to the trunk for the amp power wire. |

Silver Member Username: WaresgaragestereoFort Valley, GA Post Number: 127 Registered: Mar-08 | as long as you have the power there to run 3 amps its fine. For the HO Alternator: run a 200 apm min. http://www.db-starter-alternator.com/ has really decent prices on HO Alts. they'll have it for your car. K now, for the big 3 upgrade, go to www.knukonceptz and order 10 feet of 1/0 cable. i say 10 feet to make sure you have plenty. these folk are real cheap too! Big 3=simple its thw wire from the + batt terminal to the + alt terminal. the wire from the - batt terminal to the chassy of the car and the - wire from the engine block to the chassy. you can use a bolt on the alternator bracket for the engine to chassy ground. IF YOU PUT A HO ALT ON WITHOUD DOING THE BIG 3, BAD THINGS WILL HAPPEN... FACTORY WIRING CANNOT WITHSTAND THE CURRENT FROM HO ALT. PERIOD. go to this website for more details. you can also measure the exact lengths of wire you need and go to a Napa auto parts store and they can cut the wirte and crimp the ring terminals. personally, i order the wire and do it myself, but i own a shop to. heres that link: this goes into more detail. http://www.the12volt.com/installbay/forum_posts.asp~TID~73496~PN~1 oh by the way, if you plan on running that system with the engine off, a Yellowtop Optima or even a Kenetic Battery in the trunk wouldnt hurt. also a optima under the hood to compliment that alt. understand? |

I should buy that alternator? The One Above? and do a big 3 upgrade.... + BATT to + ALT - BATT to GROUND - ENGINE BLOCK WIRE to GROUND Is that right???? I need a yellow top battery..... Will you link me to which wire I should buy so I know how much and which to buy? www.knukonceptz.com So in total..... HO Alternator= $189 1/0 wire= $10-$20? So around $220? You said an extra battery in the trunk......alot of people told me to do this....but I am very new to sound systems...... How would I hook that up....and are there any safety hazzards? The car is a daily driver. |

Silver Member Username: WaresgaragestereoFort Valley, GA Post Number: 133 Registered: Mar-08 | wire http://www.knukonceptz.com/productDetail.cfm?prodID=KLM0BL This is copper clad aluminum wire. ive found that it works well. its 90%aluminum and 10%copper. you'll also need 1/0 ring terminals and a crimper. go to Napa for the terminals and crimper. the crimper is about 30$ not sure about the terminals. they can crimp them for you if you take them the wire. k now for the alt. yes, that will fit the car. the brackets should be the same. i've seen cars that the engines were different but the brackets are the same. a 2.2 and 2.4 bracket on a chevy sould be the same. now for the big 3 use 1/0 for ALL 3 of those wires. as you wrote: + BATT to + ALT - BATT to GROUND - ENGINE BLOCK WIRE to GROUND this IS correct. now for that xtra battery. you'll obviously need a battery. Optima Yellowtop or Kenetic battery. a kenetic is for car audio but i've seen yellowtops for car audio and they work great and come highly reccomended. anyway. u also need about 25 feet of 1/0 cable. run from the + on the batt under the hood to + on the trunk batt. next run from = on trunk batt to a GOOD GROUND in the trunk or get 25 more feet of wire and run all the way to the hoodf batt. i'd just find a good ground in the trunk. it has to be tight and all the paint under the terminal has to go. some sandpaper works good. i've seen people put 6 yellpwtops in the trunk and 2 alts. but these are for pro competition cars. thats all i can think of at the moment. let me know if you have questions. i'll be glad to share my knowledge with you. |

Gold Member Username: N2audioLawrence, Ks USA Post Number: 1563 Registered: Mar-04 | you might be putting the cart way ahead of the horse here. You haven't even talked about amps yet and people are already telling you "BIG ALT". That may be where you end up, but without knowing more about your plans it's completely out of line to recommend that. Not sure what "1000w" Sony amp you're referring to, but generally "Sony amp" and "1000w" means about 400 REAL watts, and there's no way that was solely responsible for your alternator failure. Alternators fail over time, with or without aftermarket electronics, some sooner than others. There are countless mono amps out there that are more than capable of running 4 12's, and being kenwood's I'm guessing they don't require a ton of power. You don't need two subs amps, and it would be less frustrating only having to wire one. FWIW - The ~$200 for the HO alt looks like a pretty good buy, but from what I could gather the 2.2 and 2.4 do require different alts. |

Gold Member Username: N2audioLawrence, Ks USA Post Number: 1565 Registered: Mar-04 | Class D mono around 1200w rms at 1 ohm. There are several options from around $200 to $500 or more on the high end, but there's some quality options in the $250-$300 range. Class D amps are pretty efficient. While 1200w is a lot of power an amp that size won't draw a huge amount of current unless you're really blasting it. With an amp like that along with a good 100x4 (or so) a HO alternator would probably be a pretty good idea. Especially considering a stock replacement probably won't be all that much cheaper. However, you definitely don't need 200A. A good 150A alternator would be plenty. |

New member Username: BrlntxColunbia, South Carolina United States Post Number: 5 Registered: Apr-08 | Ok, so there is a guy downtown who re-builds alternators (or does something to them).....he said he could make my stock alternator push 150A-170A for around $139 Is that a good deal? What did you mean 100x4? The CD Deck? So I should be ok doing..... 1. The Alt Re-build downtown 2. Class D Mono Amp (1200W) at 1 Ohm 3. A CD Deck pushing 100x4 (Which I have never heard of before) Spending wise..... 1. $129 2. $300 3. $100-$200????? _____________________ TOTAL: $529-$629??? I was honestly looking more along the lines of $400 damn it xD. But that sounds fine to me...... Will my current CD Deck work? It is aftermarket. Ok, now what about running my after market speakers? I have sitting in my garage.... Four 6x9s 6 Tweeters Two 6 1/2s The 6x9s are going in the back along with 4 tweeters. and 2 tweeters and the 6 1/2s are going in the front. What do I need to push those? |

Gold Member Username: N2audioLawrence, Ks USA Post Number: 1571 Registered: Mar-04 | by 100x4 I was talking about a 2nd amp to drive your other speakers. An aftermarket HU will do it, but it won't be able to keep up with your subs at anything above medium volume. Not sure where the tweeters fit in either. Are the 6.5's just woofers or do they have an integrated tweeter too? If they have the tweeter I don't think you'll need the 2nd pair. Don't forget, you're going to need another 30-50, for a wiring kit for your amp. Probably $50-80 for a two amp kit. Plus, you're going to have to come up with something for a subwoofer enclosure. 1000w+ 4 sub set-ups don't usually come together cheap. |

New member Username: BrlntxColunbia, South Carolina United States Post Number: 6 Registered: Apr-08 | Ok, I havent bought the 6.5s.
