|
sublime420 Unregistered guest | well your question doesnt make the most sense. but dual 2-ohm coils can be wired to 1-ohm or 4-ohms. Dual 4-ohm coils can be wired to 2-ohms or 8-ohms. so on the exact same amp, a sub with dual 2-0hm coils will not be the same as dual 4 ohm coils. |

New member Username: RhasslerPost Number: 5 Registered: Dec-04 | ok thanks, im kinda new to all this.. but my subs say 750 watts rms, 1500 watts peak... if i powered them at 900 watts rms.. would it damage the sub? |
|
sublime420 Unregistered guest | it really depends on what amp ur talkin bout and if its stable at 1-ohm or 2-ohms. |

sublime420 Unregistered guest | problly. What sub u talkin bout? |
|
New member Username: RhasslerPost Number: 7 Registered: Dec-04 | well i ordered all the stuff, but im wondering if i should cancel the order and change some things around. the subs are 2 kicker 12" L7's with 750 rms and 1500 peak |

New member Username: RhasslerPost Number: 8 Registered: Dec-04 | dual 2-ohm coils* |
|
sublime420 Unregistered guest | if you got the dual 2-ohm coils, then u'll be ok. if u got the dual 4-ohm coils then u'll be givin each sub 900watts rms. i dont know if they can take that. |
|
sublime420 Unregistered guest | then just wire the coils on each sub in a series and 1 sub to each channel. that will sound good. |
|
New member Username: RhasslerPost Number: 9 Registered: Dec-04 | alright, thanks a ton! |
|
Silver Member Username: HdubbFarmington, Nm Usa Post Number: 192 Registered: Nov-04 | if you run them at 900 you should be okay, but L7s have been known to crap out on people. that is a massive amp. i think you should be okay, if not just be easy on the gain settings, so they dont get completely 900 watts. i wouldnt cancel though. you should be set |

sublime420 Unregistered guest | r u installing it urself? |

New member Username: RhasslerPost Number: 10 Registered: Dec-04 | no, but im thinkin if i get 15" l7's dual 2-ohm coils, it would work out better. the specs on those are Sensitivity: 88.5 dB RMS Power Range : 75-1000 Watts Peak Power Handling: 2000 Watts Impedance: 2 Ohm Low Frequency response: 18 Hz High Frequency Response: 100 Hz Diameter: 15 Inch Features aluminum deposit cone non-resonant aluminum basket Santoprene rubber surround dual 4-ohm voice coils for wiring flexibility frequency response 18-100 Hz power range 75-1,000 watts RMS (300 watts per coil) peak power handling 2,000 watts sensitivity 88.5 dB top-mount depth 8-1/4" sealed box volume 1.5-6.0 cubic feet ported box volume 3.0-6.0 cubic feet Warranty - Onlinecarstereo.com 1 Year warranty ....the thing i dont get is "dual 4-ohm voice coils for wiring flexibility"..... the site says its dual 2-ohm, but in the description it says dual 4-ohm, but it says that same phrase for both the dual 2-ohm and the dual 4-ohm models. |
|
sublime420 Unregistered guest | if u get the 15s, then u want to get the dual 4 ohm coils. cuz then you could wire them in parallel and hook 1 sub to each channel for 900watt rms a peice. |

sublime420 Unregistered guest | this may help u out. http://www.crutchfieldadvisor.com/learningcenter/car/subwoofers_wiring.html?view =all |

Bronze Member Username: RhasslerPost Number: 11 Registered: Dec-04 | would that sound a lot better than the 12" L7's? |
|
sublime420 Unregistered guest | definatly. its just up to how much ur willing to pay. |
|
Bronze Member Username: RhasslerPost Number: 12 Registered: Dec-04 | ok, but what type of box do you think would be the best for the 12 and the 15? |
|
sublime420 Unregistered guest | personally, i'd go sealed. if you want it a little louder you could go ported, but it will take up more room. |
|
Bronze Member Username: RhasslerPost Number: 13 Registered: Dec-04 | so if i got the 15" l7's and ran them at 1 ohm, would my amp be able to take it...someone said running them at low ohms can mess things up? |
|
sublime420 Unregistered guest | ur amp could take it but the subs might not be able to. at 1 ohm ur amp will put out 1500rms a channel and the 15s are suppose to take 1000rms. but run them at 2 ohms and they will each get 900rms. that should be plenty. |
|
Bronze Member Username: RhasslerPost Number: 14 Registered: Dec-04 | ok, so if i go with the 15" Dual 4-ohm's how would i wire them, the website you sent says they can either be 1 ohm or 4 ohm loads, how would i make it 2 ohm? |

Silver Member Username: Koz1031Monticello, In United states Post Number: 368 Registered: Jul-04 | wire the voice coils in parallel and 1 channel to each sub. 900 watts each that way, then u r safe, and should be getting plenty of power, and should be loud enuff. I'd go a ported box tho. |
