Pioneer GM-7200M Car Audio Amp appears to fine but wont work
okay either my amp or my sub is messed up. seeing as my 1200 watt pioneer 12 inch sub is brand new, i dont think that is the issue. I believe it is with my amp, which is a few years old but has worked fine on subs in the past. ( my last sub blew, so that is why i bought a new one).
i have checked every wire and fuse possible and everything is alright. the red light on my amp is on and stays on indicating the power is fine. i have tweaked the audio on the head unit and amp in every way possible with no results. I'm no professional when it comes to car audio, so im sure there has to be something im forgetting or missing.
My amp appears to be just fine but my sub is not working at all, and i know it isnt a problem with the sub or head unit. My only guess is there is something inside the amp possibly messing up, i havent been able to test the sub on another amp yet, but i will very soon.

conect one of the positive terminal from the sub directli to one chanel of the amp, and do the same with the negative,and do the same with the others terminals from the sub conect to the other chanel
Nice sub, i have 2 308d4s in my car. Okay this sub is a dual coil 2 ohm. so to get best bang for your buck you'll want a 2 channel amp and bridge it. Your sub is 400 watts RMS, So you'll want an amp that has the same rating. I'd recommend the pioneer GM-5400t. Then wire your voice coils in parallel, and bridge your amp, you'll get 380 watts RMS, which is perfect for this sub. If you have questions on wiring or anything you can just ask. thanks, i hope this helps
it could be the amp it could be the way you've installed and if you have a sub in an enclosure the wires could be touching the postive and negetive speaker wires what ever the problem is the amp is in protection mode i hope this helps hope its not the amp i hope its just the wiring
you Amp is overloading and going into protection mode. if it cuts out with the wire u were using first then their would be no need to upgrade the size of ur wire cause that would only be, doubling or trippling the power u are getting threw those wire now. bottom line the 2 subs u are using are obviously to much for the amp.
try dropping the OHM's by connection the subs together and runnig just a single positive and negative to the amp! or just get a better amp
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
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.
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.
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
