hi i recently fitted a subwoofer and front speakers to my subaru im running the front speakers from an amp and also the subwoofer from an amp, everything was ok but one morning i got into my car and started playing the music but i could here the engine noise coming out of the speakers which was quite loud, what i cant undertand is though that there engine noise was not there for the first 2 weeks and then over night without me making any changes the engine noise started coming from the speakers, anyone have any ideas of what happened here?

If its not your earth (90% of the time it is) its your amp thats fooked, you can buy a suppresor(sp) thats supposed to eliminate this but rarely work, all from experience my friend lol

your picking interference from somewere then,

you can buy ground look isolators to surpress the noise, but usually the noise is there from the start,

how is the system wired and earthed?

Try making sure your power leads to the amp are down one side of the car,with the actual speaker wires down the other side.
Running them all together can pickup noise through the power lead.
