I have 2 4 ohm 12" audiobahn jw1251j and a 1500 watt mono planet audio amp. what ohm do i wire the subs to the amp

Your amp is under powered for those speakers (350 max. watt). Even if your subs were 2 ohm your amp will only put out 75 watts X 2 at 2 ohms, if you bridge that amp you might be asking for trouble . I'm guessing there both 4 ohm. Look around for a 2 ohm stable mono amp with more power and you won't be sorry. Ray

for your subs and amp the best way would be for the speakers to be wired in series1ch (mono or bridged)to have a 4 ohm load to your amp stable at 2 ohms
see pic for wiring diagram for 2 1 ohm dvc subs wired in series.
you will need more than one speaker wire for wiring the subwoofers coils(positive & negative terminals) together
hope this helps :~)

This could be caused due to the impedance load being to low. Your amp is stable to 2 ohm load however its very possible that you have your subs wired to a 1 ohm load that would cause the amp to go into protect mode. The subs you have are dual 4 ohm voice coils and would need to be wired in series/parallel. I've included a link that will show you how the subs should be wired.

You need to wire them according to the limitations of your amp you can pull a 1 ohm overall load just by connecting all of your coils in parallel- or you can get an overall load of 4 ohms by wiring each sub individually in a series configuration which will yield a 12 ohm load per sub -and then wire the 3 sets in parallel which will bring your ohms back down to 4. You can do a lot with that many coils it depends on your amp really-ideally a 1 ohm stable class d mono amp that is 1000-1500 watts rms would knock the **** outta those things JL is the good stuff.

yor subs have dual 6 ohm voice coils from the sound of it-your amp is rated at 650 watts rms at a 1ohm load. The best you can do with the equipment you have is to wire ALL the coils of your subs in parallel and that will give you a 1.5 ohm load for the amp.It should knock the hell outta them with 300 watts on each sub - good luck

The amplifier is only stable to 2 ohms.
Assuming the cubs are dual 4 ohm voicecoils - a 2 ohm load with 2 subs is not possible.
You can only wire up 1 dual 4 ohm voicecoil sub (both positives to amp... and both negatives to amp) to get a 2 ohm mono load.

+ on amp output to + on speaker #1 to + on speaker #2. - on amp output to - on speaker #1 to - on speaker #2. This is a parallel circuit....4 ohms in parallel with 4 ohms = 2 ohms. IF it were wired in series....would represent 8 ohm load.

Bridge it. Should be marked on amp. According to specs should get u the power u need. Amp max 1500 watts. at 2 ohms. Speaker max is 2200 watts at 4 ohms. Turn amp down and adjust to your own taste. trust your ear man.

Mamola,

Get an amp with at least 200 Watts RMS. The RMS value is what is important about driving Subs. This could be proclaimed to be a 1000 Watt amp. REad the RMS value.

Wiring. It is better to series your Speakers to give them and your amp more reliability,

Get a Mono or Bridgeable amp. If it si bridgeable, BRidge the output as described in the manual you get. Some Amps have a diagram right on the output..

AMP+ to Sub1 +
Sub1 - to Sub2 +
Sub2 - to Amp -

Get a 4 Guage wring kit. Run your power wiring down the Drivers side, and Audio signal wiring down the Passenger side, keep the two separate.
