i need some 6.5 comps for rear fill. my current set up is some s17 type rs. 87db sensitivity. i really don't mind if the back gets louder cuz its a civic coupe. i have an extra 400w to power them. also soundeadener, and just random stuff. maybe some 2/0 welding cable about 4 ft. some 16 gauge speaker wire only need about 10 feet. stuff like that.
