Re: more bass

Run one set of RCA lines from head unit to amps if you only have one set of pre-outs on the head unit, then at the amps, use an electronic crossover to split between the two amps, and this will also allow you to control what frequencies go to which amps/speakers. You should use one amp for the speakers and the higher power amp for the subwoofer. You should not try to connect both to the subwoofer. Use 4gauge cables if possible. If you have more questions, just ask.

Amps on woofers are fine just won't hit

your probably making your amp run to low ohms if its a 2 channel amp bridged to one channel you can probably only run it at four ohms

Also seeing as your subs are 2ohm dvc you can't wire them individually to 2ohm and use each channel separately. So i'd recommend buying a 2ohm stable monoblock or running it at four ohms. a 1400 watt amp'll still pound at 4ohms and it'll extend your amp's life span

Hooking up a new 8" woofer speaker to my amplifier

If I'm reading the amp manual right, you should be able to connect the amp in 3 channel mode. To do this:
  • Connect both left door speakers in parallel to Ch A Left.
  • Connect both right door speakers in parallel to Ch A Right.
  • Bridge Ch B and connect it to the new 8" sub.
  • Set the Ch A LPF/HPF to HPF.
  • Set the Ch B LPF/HPF to LPF.
This should allow you to run all 4 door speakers and the sub from the amp. It will also automatically route non-bass to the door speakers and "only bass" to the sub.

It should be better to use the Pioneer GM-7200M Amp with your subs.

For 8 ohm setup hook up this way:
Amp out+ to Sub1 +
Sub1 - to Sub 2 +
Amp out - to Sub2 -

For 2 ohm setup hook up this way:
Amp + to Sub1 +
Sub1 + to Sub2 +
Amp - to Sub1 -
Sub1 - to Sub2 -

Witch is better

hi there. ill start with the wiring. you should have a blue remote lead going to the back of your head unit, the power cable running straight from the amp to the battry, the earth should be earthed in a fairly decent place, any metal inside the car realy, and then your wires pos and neg from the amp to the subs. the reason why the kenwood might not have much base on it is to my knowledge, there should be a switch somewhere on the amp that will increase or decrease the power input for the speakers, if this is set very low then hense why theres not much base comming from them. if the amp is on and its giving something to the subs it probably isnt the wiring. try checking the amp for the switch first, if you cant find it try the pioneer amp and see if theres any diference.
dont hesitate to contact me if you get stuck

cheers, adam

Is it good

If you are using a GM-7200 amp, it should sound great. Both the amp and the subs are rated at 800 watts so be careful not to overload the bass by turning them on full power. It is good practice to have a slightly lower watt amp than the subwoofers. If you can power your rear speakers from the amp, that would take away some power to prevent the subs from overloading. Overall, you should get a nice THUMP!!

u should connect at least six 12" subwoofers (preferably 1000W each) to that pioneer amp of yours. Crank it up and enjoy. Your amp shouldn't cut off now. If it does cut off, you should change the fuse on your amp to a higher ampere.

Amp is on, Subwoofer works, but no sound.

here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem
