I recently installed a new cd player and now when i turn it up to a mid-high level it blows the fuse under the hood. Its a 7.5 amp fuse and that is what is speced for the car so i dont think going to a 10 amp fuse would be key. Prior to the new cd player installed are 2 amps, 200w for the subs and 180w for the mids and highs. Everything was working fine before the new unit. Use to have a cd player along with an eq before they got stolen but now with just the cd player in alone i keep blowing fuses like i said at mid high range noise levels. I also already checked the wiring for shorts and found none.

any suggestions?

Since most CD players come with a 10 amp fuse in the back of them I don't think that 7.5 amp fuse is gonna feed both your cd player and whatever else is on the circuit. If it comes down to it run a dedicated power line from the ignition harness (with a fuse) to your cd player. Good luck

Bottom line is there is no way a 7.5amp fuse can run a head unit at full volume let alone a head unit and a pair of amps i suggest you inrease the fuse amperage to at least 40 amps and see.

Do what NowYaKnow suggested an run a designated power wire for these components. If you just keep increasing the amperage of the fuse on the same wire, you run the risk of a fire or melting the wiring that the components are attached to.

I seem to be missing something here,you said you have two amps and a eq on the original hook-up so therefore ,the fuse that is being blown is it coming off a main power wire that you installed to run the entire system or is it the factory installed fuse in that black box that also houses the headlamp fuses and relays.

check all of your speaker wire connections too. If they are out of phase that result in a blown fuse at high levels
