I have a Kicker 08S15L72 15 dual 2-ohm need it wired for 4 ohm
I have a Kicker 08S15L72 15" 2000W Dual 2-Ohm Subwoofer and im hooking it up to a Alpine PDX-1.1000 which works at 1000rms @ 2/4ohms and was told to set the sub and amp to work at 4 ohms how exactly would i wire it so that the sub is at 4ohms
Re: i have a Kicker 08S15L72 15 dual 2-ohm need it wired...
Ok im going to try to explain this you have 2 voice coils , i will refer to as vc1 and vc2, you take vc1 positive and connect to vc2 neg then use vc1 neg and vc2 pos to the amp according to pos and neg signs.

To do this they MUST be wired in parallel, IE: Plus to Plus, Negative to Negative. 2 4 OHMS in parallel is about 2 OHMS in series it would be 8 OHMS... series is positive to negative. Are you using a crossover network?
You should never connect a load of an impedance less than the min the amp is able to drive. This can have disastrous consequences that may easily result in failure of the amps output stages. You need to use a different configuration that does not overload the amp in this manner for safe operation.
You have a 2 ohm stable amp, and dual voice coil subs.. The L7's come in both Dual 4 ohm, and Dual 2 ohm, so you have to know what impedance your coils are prior to wiring. HERE is a nifty little guide that will show you how to wire your subs. DO NOT WIRE THE SUBS LOWER THAN 2 OHMS ON YOUR AMPLIFIER!
If you have the version with 2 ohm voice coils, you want to use the 2nd diagram for a final load of 4 ohms to the amp. The 1 ohm load is too low for the amp and will cause it to overheat and possibly fail. If you have the 4 ohm version, use the wiring shown in the 3rd diagram which is a perfect match for the amp.
Are these Dual Voicecoil Subwoofers? Are there 4 terminals on each sub for wires?
If they are Dual 4 ohm voicecoil subwoofers
- connect both + on subwoofer 1
- connect both - on subwoofer 2
- connect both + on subwoofer 2
- connect both - on subwoofer 1
This will give you a 2 ohm STEREO load.
To get a 1 ohm MONO load...
now connect only one of the + on EACH sub to the + on the amplifier.
and the - on EACH sub to the - on the amplifier.
You now have a 1 ohm mono load.
If your speakers are 4ohm single voicecoils (one pair of terminals) the lowest impedence possible is 2 ohms.
This is wired in the same fashion. Both + on the subwoofers to the + on the amp, and both - on the subwoofers to the - on the amp.

they are dual 2 ohm all L7 are 2 voice coil per speaker so it is like 2 speakers not 1 the dual 2 ohm version is so you can use 2 speakers wired in series to get a 2 ohm load 2 ohms + 2 ohms = 4 ohms then parralel the 2 at the amp to cut it in half to get 2 ohms. I have full warranties on mine and i dont really sell alot of them any way I prefer the hifonics they sound better last alot longer and take way more power and put out 3 times as much sound. but i can check it out if you have the info.
