i just installed a pioneer deck and subwoofers and amp in my blazer i never had any problems till then i was wondering if that could cause my dash lights and gauges to reset like i just started the truck if so what could cause that, the stereo is wired correctly with all the needed components for it please help. p.s. could it be the alternator, als i dont have a capacitor hooked up to it.

 

not sure what your question or your problem is, but you can get the alt tested at autozone or similar place. make sure that you have a solid ground for your amp and forget about the cap.

 

just had everything tested and it came up fine maybe its the computer, i dont know.
