Major engine noise and feed back

[Macfadyen732]

ok so my sister is going to be taking over my car so i can get something more family oriented. have a 7/mo old girl and need something bigger.

Car is a 2009 Hyundai accent hatch

so today i took out my jensen flip up dvd screen to put in her pioneer h/u. after i get it all wired i test it. first thing my subs do when i turn the key is pop. then starting the car i get major alt. noise.

what is causing it. i had no noise with both the kenwood that i originally had and the jenson.

every time my volume goes from 1-0 the subs pop

if needed i can put up a vid from my cell.

You may have blown the pico fuse. It's a common problem with pioneers. Search it up. There is a band aid that involves wrapping bare wire around the RCA outputs and grounding them to the radio chassis.
