First I would like to say this forum is dope and has helped me with alot of my problems. But i finally joined to ask this question.

Anyways sometime last week my headunit (Clarion DXZ745MP) just stopped outputting sound out of no where. However, everything like the lights, radio, etc still work. I take out the hu and the cd is still spinning inside. Sometimes when Im driving though sound comes out for a song or two then the sound just dies again. So obviously my question is.. wtf is up with my HU?

btw there are no external amps and Im running a set of Crystal CSC60s components for the front and lil pioneer 4x6s for the rear. Any kind of help would be appreciated.

My guess - blown speaker that's shorting out the amp in the deck. Start disconnecting one speaker at a time, see if the rest of them come back on.

I'm not sure, but I think some Preludes have a flaky amplified rear speaker system. If you're using stock wiring and a harness, you might have to try running new speaker wire to the rear speakers.

im going to try that after i come back home. it can be that since im running little 4x6s for the rear and comps for the front. any more help would be appreciated

just to clarify.. it has nothing to do with the internals of the hu right?

my hu does output sound but it puts out next to no sound at all.. i have my hu set at full volume and i can BARELY hear it.. i kno its there and every speaker is working but the sound is dead quiet.

Possibly factory amplified? What kind of car?

nope.. cant be factory amplified since my car is a 240sx base model so it didnt come with the amps found in the SE models

Have you tried trouble shooting by disconnecting the speakers one at a time yet? It's either that, or a bad amp in the deck (in which case, yes, and external amp would solve the issue by going through the pre-outs).

doesn't that deck have a feature where you can shut off the internal amp? maybe that got shut off.

i thought that was only on the alpine? it could be on this one also though.

according to sounddomain's description, the deck has an amplifier bypass circuit so i'm assuming that means you can shut off the internal amp. i wish pioneer had that feature :(
