    I drive a '93 Chevy Cavalier sedan. Bit old, but eh, it was free when my much newer car died. It came with a Kenwood KDC-132 stereo in it.

    I'm wiring in a Dual XIA2460 amp (two-channel 460 amps). I bought a wiring kit (Scosche, up to 680 amps), hooked it all up right, as far as I could tell. Blue remote wire went to the red "ignition" wire connected from the car to the stereo... that's right, right?

    I powered it on, and the RDO2 fuse (10A, powers the car stereo) blew. I disconnected the blue remote wire, replaced the fuse, and the stereo worked again. Turned it all off, reconnected remote wire, powered it back on and the fuse blew again.

    As far as I can tell, there are no exposed wires. I guess the amp is just trying to draw too much from that remote wire and the 10A fuse can't handle the increased draw.

    So, my question is... do any of you guys know anything that I can do to fix this? Perhaps any known kinks involved with one of my components, and a workaround? Or what's up? I'm going to be asking the guy I got the amp from later about it, hopefully he'll know something, but I mean, if you guys can help out, that'd be sweet.

    whoa!! if i read this right your connecting the radios blue remote out to the acc out from the ignition. thats a big NO!

    the blue wire from the head goes to the amps remote turn on.

    Yeah, I figured that out and corrected the wiring. Fuse isn't blowing, but the amp isn't powering up now. May be a faulty ground preventing it from powering up, or it could be a bad amp. I'm going to pull out my old amp and see if I can't get it working, and if that doesn't do it, I'll try out a different ground location.

    It could also turn out that the stereo just isn't sending a signal, too, but that's an easy fix too - I plan on switching stereos with my wife's (which is really mine) tomorrow.

    is your remote out going to the amp to turn it on? chances are the way it was wired fried the output for the remote turn on.

    Wow, okay, I can't believe you really just said that. Even I can tell that couldn't have happened. Besides the number of other factors that eliminate that possibility, the fuse blowing prevented it. Electronics 101, buddy. I guarantee that wasn't what happened.

    ok, your amp isnt turning on is it. then something did happen. try this. use a small jumper wire from the amps 12v power in and jump it to the remote turn on of the amp.

    if the amp turns on then there is something going on with the remote out on your head unit.

    just because its fused and it blew it it still got a voltage spike and may have damaged the remote output on the head.

    again like i said before.. if i read your 1st post right. you wired your remote 12v out to the cars 12v out for stereo power. that may have done it then. if i read that wrong then.."oops my bad" :)

    If there is no short in the remote wire, I would guess there is somethng wrong with the amp. The remote turn on, on the amp should require less than 300mA. There is no way it should have blown a 10-amp fuse, peroid.

    At this point, you need a meter. Check for continuity between ground and your remote wire. If you have continuity, you have a problem.
