… and I wouldn’t bother with rear speakers. all they do is muddy the image and fuck the soundstage, and cost you more money. ask anyone who heard my setup in the Z before I took the car apart for the cage, you still heard shit in a very “3D” way out of only front speakers…
i do it to be nice to my rear passengers, cause blose systems are know for the great sound, that and I melted a fuse wire to my rear speakers and did not feel like finding it so I amped them
add sub and a sub amp
if not enuff
add a 4ch amp for your stock mids and highs
if not enuff add a comp set or 2
or just go ahead from the start and get yourself a nice 5ch.
