Zapco DSPZ8 repair?

Post by LowBassSubs »

Hi all, I am looking to get my dsp z8 2012 version repaired.

It stays on even when the remote wire is disconnected. Because i cannot leave it connected when restoring power it takes like 20 mins give or take to connect to the computer. Meanwhile the speakers have a white noise sound. Then computer dings a notification sound of like when you connect something like a external hardrive. The speakers buzz like there is a switch being turned on. Then I have to load my preset to get it working.

Also it cuts out when I start driving. No issues elsewhere just the dsp. 14vdc when this happens. BYPASS the dsp and the amp plays. Makes a sucking pop sound like some warp speed kinda sound then stops playing. Tried to load and cycle power no luck. I did not have this issue prior to the dsp. All power is solid. Grounds to the frame and positive 0/1g to the battery.

Any help is greatly appreciated. I could make repairs myself, but am not sure what to look for. Any pointers?

Thank you for your time.

That sounds like a power supply problem. Pull the cover off and look for bad caps.
