i have 2 polk 12's, a lanzar vibe 435 (i think thats right...?) 1000w amp. i had it in my blazer and got no engine noise (it was also with a much better cd player) and now we put them in my friends car and his engine noise is SO loud coming from the subs in the trunk.
what is causing this and how can i fix it?
