Pioneer DEH P7700MP Problem

[Haserfauld]

Hey guys,

I have a problem. I bought a P7700MP off eBay (it was new) a couple months ago, and installed it myself in my 1988 Civic. I got a set of 4 OZ speakers and installed them myself. I did the harness myself as well (used heatshrink and solder). Now, a few days ago while playing a CD, suddenly the sound stopped. All 4 speakers at once. I shut off the HU and turned it back on, and still nothing.

When I turn the HU on, I get a "CLICK" in the speakers, but nothing beyond that. The HU seems to function perfectly (display, ability to pick up radio stations and such), but no audio. I disconnected the harness and plugged in the old factory HU and it works fine. So basically, the problem is either my HU or the harness. Is there any scenario in which the harness would fail and cause all 4 speakers to cut out at once, but allow the HU to remain powered and all that?

Or, is it more likely my HU is busted?

Thanks for any help

have you tried to see if your speaker are grounded anywhere? i have a 93 civic and my sound use to go but come back when i hit a bump..try tapping around each speaker..if that dont work..try another head unit..and if that one is busted i'll give you 30 bucks for the face

ha i doubt a little tap is gunna fix that problem...pioneers are said to have grounding issues but something could have arched and blew the fuse on the back of HU. ive had it happen before.... the fuse on the headunit blow but it still had power? it was odd...
