HU problem help if possible

[MDDrew 10+ year member]

I here what sounds like ignition noise thru my speakers, i recently had my kenwood mp828 stolen and i bought another kenwood and had it installed. now i didnt have this problem with the kenwood that got stolen but i did have this problem with the clarion before that deck, it was only and the tweeters now i believe its in all the speakers. could this be a ground problem?

also could it be the 4volt preouts vs the 5outs of the stolen kenwood?

its 3 deck total clarion= 4 volts kenwood = 5 volts and 2nd kenwood = 4 volts

Check your grounds, make sure all connections are secure and all fuses are good. My noise problem was because of a busted internal fuse in my HU.

The repair sheet I got back from Pioneer said "Fixed broken outgoing fuse" Speakers that were attached to the deck worked fine, but the pre-outs sent a lot of noise to the amps.
