I have an alpine hu cda105 and i just installed 6 new infinity 6032cfs in my car + the 12'' infinity sub and amp, + 6 other speakers in just my trunk and for some reason unknown to me it keeps reading dc error which means theres a wire grounding out some where but... i just took all the doors and speakers out and everything is connected and fine. plus when the cars in acc power (engine not running) the speakers work fine and can go as loud as i feel but when the engine is running the speakers can only go for a while before a dc error is poping up... so my thoughts are 1. a new/bigger battery?? 2.bigger amp 3. shorted wire 4. just burn the dam thing and say it was stolen?? lol thanks for any help

have you checked the knock sensor? This is a common issue with the older models it will give a rough idle and reduced gas mileage.

In my case, the problem turned out to be the after-market radio which is on the same circuit as the interior lights and clock. Once it was changed, the problem was solved.

i would suggest disconnecting the battery for 30mns then connecting this some times clears the code othr wise replace the sensor

Ok, well I doubt very much that changing the engine would cure all of the faults. If say a piston had gone bad ( and they have been known to without warning) it would not cause all of the fault codes to read. I would start checking all of the wiring connections especially the earth wires as the early Subarus did not have very good wiring. Also check to make sure no water has got into the fusebox area.

Drop in to an Autozone, or Pep Boys, or similar big parts store & they will usually scan for codes free. This will hopefully eliminate all the guess work, or at least point everyone in right direction for better diagnosis. If not obvious from codes what the problem is, get back to us and we'll help you out.
Testimonial: "Thanks for the great suggestion . I'll have Autozone read the codes on Monday. Thanks again!"
