Ok on my 96 Bronco I just put in a new amp and it worked great for about 4 days, its a RF 1200W amp going to two pioneer 12" subs, and when i turn on the car they make this low humming sound and when i rev the engine the sound kind revs w/ it. Sometimes it will work great, sometimes it will do the buzzing real loud and i turn the cdplayer off. Can anybody tell me what might be going on so i can fix this.

check your grounds

Definately poor ground. It's best to run a ground block from the batt to the cab (8ga or so), then tap off for amps there.

i will keep you updated as to if it works

It sounds like one of your RCA cables is touching something metal. Check those as well as the ground.

also make sure your ground is as big as your power cable

Are your RCA cable running with your power wire. If so get them away from it. That would be where you are getting your interference. Installed stereos for 2 1/2 years back home and saw some stuff like this all the time. RCA's should alway be run seperatly if at all possible. It is ok to run the remote wire off of the CD player with the RCA's though. Also make sure you have sheilded RCA cables that will make a big difference.
