Help, Factory HU lights up, but no music

I recently removed my subwoofer to accommodate some luggage for a road trip. I rewired my amp to my back speakers, but I figure I messed up because now, my stereo is broken. It light up as usual, displays the radio station or the cd track but there is no sound from any of the 4 car speakers? Any advice?

Check wiring on the amp. If you are using factory HU.. you are probably tapping low/high signals off the rear speakers... Check wiring going to amp. Is amp turning on?

Usually on stock 2001+ Civic decks, you don't need to connect the remote wire to anywhere (because there's no remote wire location anywhere on the back of that deck).

Yeah. My Amp is turning on, But that still doesn't explain why the front speakers don't work since they are connected directly to the HU.

How did you wire your amp into your rear speakers? If you connected your amp to your rear speakers without unhooking them from your deck then you probably fried both your deck and your amp.

I would completely unhook the amp and disconnect the rear speakers and set the fader on the headunit all the way to the front and see if you get sound out the front speakers. Just a thought.

Yeah, I tried that thanks dups. I guess I fried the HU. Oh well, looks like I'll have to replace it with a better, more powerful one .

I can't imagine that you fried the headunit though. One more thing I just thought of. I have a friend that has a Chevy Tahoe and the same thing happened on his headunit. It turned out it was going into some sort of 'protection' mode. I think what happened was one of the speaker wires going to the speaker level inputs on the amp got shorted out. We ran it through a panel and there was a screw holding the panel in, when we screwed down the panel the screw cut through the insulation on the speaker wire and shorted it so the headunit didn't play. If you're sure you got everything like that undone, I would also try maybe unplugging the battery and waiting a few minutes and reconnect it to clear the headunit and see if maybe it just needs to be reset or something. I don't know, but it might be worth a shot?

That's the wierd thing, it still turns on and operates as usual, that's why I can't imagine it's toasted. I'll try your suggestion, it just might work.

There is an amplifier inside radios and thats what you might have fried, anyway if you have a multimeter unplug the harness out of your radio and probe the positive test lead of the meter on a ground source and with meter set to contnuity test all 8 of your speaker wires and make sure that none of them are grounded out because if your lucky it might not be fried yet you might just have one of your speaker wires grounded out
