Hi, I notice when both my aftermarket radiator fan turns that my stereo is quiet for a sec and returns back to normal. The lites doesnt get dim and the head unit doesnt turn off. I'm running a DD headunit and a 10" sub powered by 1 amp. It doesnt happen when 1 fan is on but once the AC fan kicks on I can hear drop in vol and then returns back to normal. Will a capacitor solve this problem or is this something else?

 

that's not really a problem. it's not really a big deal electronically, you can add a cap if your want

 

it's just annoying that the volume gets lower everytime the 2nd fan kicks on. I really dont want to spend 100 dollars on something that wont solve the issue.

 

what amp do you have? do you have an aftermarket deck?
quickly I'd say check/redo the grounds on both the amp and deck(if aftermarket). more the deck though, we have ****ty grounds in the car's stereo wiring.
