Little Audio Problems/Diagnosis

[djsk8r33]

long story short.

-truck came with crappy jvc headunit.
-put a friends alpine cde 9874 in.
[and it gives me hi temp and a weird error. when i turn volume up. past around 20+ it wont play and says 'disc' if its playing cd, or 'tuner' if its playing radio]
-today i bought a new alpine cde 9883
after installion(just switching out, sicne everything is already spliced and connected from the other alpine) i still get the same error msgs. its really quite annoying



is there something apparently wrong in the wiring? or something i dont know.

if you need any further info, LMK

I'd redo all of the wiring

Ditto. It sounds like the initial installation was bad. Actually, I'd try to get the original harness replaced, and use proper harnesses, just to avoid any issues in teh future. Metra sells the car replacement harnesses.

if there is a specific something i should know, thatd be great.

but i am going to do that. im going to re-splice evcerything and wire it back up.

it also does it in a buddy car that was wired professionally (do mine myself) with the alpine, but not his sony

That almost sounds like a speaker with a partially open coil. It's causing the unit to shut off, but maybe not. This one will be hard to troubleshoot over the 'net.

are you talking about the error when it wont go loud? how do i fix this? new speakers? i just got new ones for the back, but the old ones were completely blown so i guess that doesnt make a difference

Sort of. It may be just a universal error code, but when you try to go louder, you coax more excursion from the speakers. If one is partially open, it would reach that shorted point when you turned the volume up- causing the protection circuitry to kick in. It's kinda off-the-wall, but I've seen it more than once.
