    Stereo RCA's blown?

    Yesterday I installed a my uncles amp a Bazooka El1500 in his Honda. When I turned it off (and on) the subs make this popping sound. I then reinstalled a kenwwood amp in his car and it made the same popping sound. So then I connected the Kenwood amp RCA's diffrently, by running it from the back speaker wires(the bazzoka amp doesnt have these feature) and it stopped making the popping sound. What could it be?

    Loose ground connection? Make sure all terminals are solidly soldered and there's a tight connection between the RCA jack and the plug.

    If the ground is good then the remote on lead is the next in line to look at, when you hooked the kenwood up to the speakerleads you curcumvented the remote on line.
    A delay circuit on the remote on lead or a new HU will fix the problem.

    The amp Bazooka amp I installed in his car was mine i sold it to him. When I had it, it did not make the popping sound from the subs.

    Today I went to my uncles house I reinstalled it in my car and the popping sound was gone. So how do you explain this???

    Re: Stereo RCA's blown?

    There's probably a ground loop between the HU and amp. Connecting RCA's connects the amp and HU grounds together. Engine whine, pop, etc are usual symptoms. Using speaker level inputs eliminates the inter-ground connection. Proper solution would no doubt have revolved around regrounding HU and/or amp.

    it is a ground problem. RCA wire hardly, if ever blows.
