i have a mtx thunderform enclosure with two ten inch 4500 series subs in a dodge dakota club cab. Im powering it using a profile california 2 CH AP1000 amp. my problem is theres alot of unwanted noises. i have the crossover set to low and have tried playing around with the gain and low frequency adjustment with little change. the low frequency adjustment doesnt help any and when i putt the gain all the way down some of the noise goes away. its like a humming noise that i even have when the volume is turned to zero. also when i turn on the lights and change the station or input on the stereo it seems to send more juice to the subs n causes a poping noise. I have tried using my brothers kenwood amp and sub set up with the same deal. I have also tried changing the location of the rca cables, replacing with different rca cables and trying a different ground. I am completly stumped. Any help would be greatly appreciated. Thanks wes
It would seem that you are on the right track but put a plan together to solve the problem. Start with the power supply. Can you temporarily power your WHOLE system directly from the battery with the engine off? It could be the noise is upstream of where you are checking in that the noise is in the power supply of the head unit (you just haven't notices the noise in the other speakers. If the noise still occurs you have eliminated the power supply, you can then move to the output of the head unit checking all of the wires nd components all the way to the sub speakers.
dont mean to steal this thread but i have exactly the same prob. im using a jvc hu. the first time i installed it with a amp kit from walmart it worked fine. But i took everything out cause i was going to trade it in. but i didnt so i installed again using a boss 4 gauge and i got this noise. im guessing cheap amp kit .
I think the problem is that the OEM wire is BARELY capable of handling the OEM radio (trust me on that one) and I am guessing that you are re-using that wire to power your Pioneer. If so you need to temporarily replace the OEM wire.
All you need to do is replace power the head unit with some lamp cord temporarily running from the battery over the engine compartment in through the door and to the power and ground of the head unit. Then try to recreate the noise you heard.
