Dash speaker the speaker is broken or it brumm when the radoi or cd is on

check fuse

recheck your speaker connections..you have 2 sets of two at least 2 front and 2 rear ..that should be 8 total..normally in matched colored pairs..the radoi colors may be different but you can figure out which is which..

your amp in the truck is probly the problem

Hello!
As others met as a problem and I as well, 1st contact spray the imput selector box in through every orifice you can(the can type box rear on the right side inside the amplifier), placing some paper towels in so that the excess spray with maybe dirt or oxide falls on them and not make a mess inside the amplifier(oily wet contact spray)! Afterwards restart the amplifier and select from first to last the sources and repeat the steps from the begining to here with the amplifier off for about four times! That should do! If not try cleaning the relays in the back middle after removing the cap with some sandpaper of the brumm that it has developed allong time! If that does not work 1st tighten at all ends the connections of the speaker cables(amplifier - speakers), and if not than maybe the transistors are burnt or cold solders are on the board! Good luck!

check the box under the hood for a fuse that says start or ign,, also check the starter relay

Hi,

There is a step by step guide with pictures throughout showing how to do this at this link.

Thanks for using FixYa. Please do leave a vote for the solution if it helps.

Put the fuses back in.

check for loose and worn out wires and fuses or fusible link and the wires connecting to the battery.

hey you probably got a short fuse somewhere check under your passenger side or your side on the floor there should be a fuse box check them out and replace te ones broken.

put a noise condenser on the radio power and use a different ground other than the factory ground for the radoi,use the fire wall behnd the dash.
