Hello thanks for reading I recently wired up an amp in my 91 crx I have it running to all the speakers when I start the car sometimes it will kick out this loud buzzing noise that is to loud to let sit and play while I search around for what's causing it, i really don't know much about amps but as soon as the radio kicks on it will buzz so loud if I fiddle around with stuff it sometimes stops and I've never had it happen while I was driving

 

I just now figured out its only when I first start the car in I. If I got to II. On the ignition it only buzzes for a second then goes back to behaving properly so I have no clue why but at least it should happen when I'm driving because it is so loud it scares the hell out of you

 

Maybe you don't have enough power..

 

I had one other commentor suggest that. my battery is small but not necessarily too small being that the car is a 91 crx it's an absolute loud noise though and sometimes I'll still get it when the car is off in the first notch

 

It may be feedback coming in from the RCAs. Get some ear plugs, turn the car on so that it makes the buzzing sound, then unplug ONE RCA cable and see if the buzzing stops, if not plug it back in and move to the next RCA cable then repeat for the rest. If that doesn't come up with anything, do the same with the speaker wires coming off the amp. And by one at a time I don't mean one SET or PAIR, I mean one actual side of a set(like the red stripe or black stripe) or the positive/negative speaker wire.
