After some advice really. I have a 1996 A4 and currently am just running some 5 1/4 Kenwood Dual Mag Comps in the front doors off of my HU which is an Alpine 7893 I think, which has the V drive built in. At the weekend I removed the rear panel speakers as they were blown. Now I need something to replace them with. Should I just stick some Co-ax's back in or is there another option? What about a sub for the boot? Would I still need some speakers on the rear shelf? I see JL do some 6.5 mid range / mid bass speakers could these be fitted in the rear deck or are these only for enclosures? Any ideas as Im not sure whats going to be best. By the way I listen mainly to house and techno so some punchy bass would be nice.
