Rumbling from subs

[sonikaccord]

hmm i need to find another amp to try cause this is my friends hes letting me borrow, never had that happen. I guess its time for a new amp so i can give this one back. and whats wrong with pioneer HU's?

They blow pico fuses and you get alternator whine and other noise.

amp might not be getting enough continuous power

Sorry, but that doesn't make sense.
What's continuous power?

hmm now that i think about it you said a blown pico fuse will make like alt whine and whatever occur. Well it did sound like the sub was rumbling like the car at idle so from there im guessing a blown pico fuse? time for a new HU if thats the cause.

It's fixable. You have to ground your rca's to the radios chassis.

i ment like the alternator might not be putting out enough volts....i had this problem in one of my cars where if the volts where to low the subs would make funny distorted sounds when real low notes hit

OP, do your headlights light up the road 5 feet in front of you? Yes? Okay, problem's not low voltage. It's the pico fuse, it's always a pico fuse on pioneers.

if i didnt have enough voltage then my car would of died, cause my old amp was huge and used lots of power. but im guessing its the pico fuse since its got the car idle going through the sub. but im going to try the grounding the rca's first see if it does anything.

Run a new wire to the HU and run it to the chassis for a new ground, this will fix white noise in all the speakers. If its just in the subs then check the RCAs or swap the amp, If no help then its the subs. Are the subs DVC or SVC? Might be a bad VC in one of the subs.
