Serious problem with my Car Audio System...

I have a Clarion DPH7500z Digital Sound Processor connected to my Clarion Pro Audio Head

Unit. I am running all CeNet wires. More frequently than not, my head unit will either go

silent or will splatter with noise. I've traced it back to the DSP because when I unplug the

DSP and plug it back in my head unit will do a system reset and then my sound comes back.

This happens almost every day now. It has progressively worsened with time. It has been

happening for at least a year now. My equipment is about 6 years old now but has never given

me a problem.

Equipment:
Head Unit - Clarion Pro Audio DRX9575Rz 4V CeNet
6-Disc CD Changer - Clarion CDC655z 4V CeNet
(4) 10" Orion Series3 Subwoofers (custom sealed box)
(4) A/D/S 5-1/2" Front/Rear Speakers
(2) Orion HCCA 225rR Amplifiers (each amp runs 2 subs)
(1) Soundstream Reference 200 Amp (runs front door speakers)
(1) Soundstream Rubicon Lil'Wonder Amp (runs back door speakers)
Direct Connector solid brass fuse boxes 60A Gold fuses
Rockford Fosgate RP1020B Wiring with a mixture of Phoenix Gold

Does anybody know what I should do?

Thank you very much for your help

Have you checked your power connections?

Installer1 is an unknown quantity at this point



voltage and grounds........75 % of most probs are lack of voltage or a bad ground. Those are some older pieces, and if I remember correctly, the dsp pulls its power through the din cable......so if there is low voltage at the radio then your dsp will lack lots of voltage. May be enough for a microprocessor to act funny.

Try using a relay with the direct power coming from the batt. and then try finding a good location for a ground, clean any paint away from the metal and tap.....

Another Question?

If my battery is getting old, would this cause the problems?
