In my 92 Paseo, I have...
Alpine 7840
AudioControl THREE.1
Infinity Kappa 4" components in the front doors
Infinity Kappa 6½" coaxials in the rear deck
Kicker 10" 2ohm round Solobaric
Rockford Fosgate Punch 60 powering the Infinity Kappas
Kicker DX350 powering the Solobaric
647 total watts. Stock cold weather alternator. No cap. Sears Diehard Gold battery.
I rotated the stock front speaker mounting brackets so aim them more toward the front seats instead of under the dash. The tweeters are mounted in a PVC endcap which are bolted to an empty bolt hole from the rotation. Holes were drilled in the stock speaker grill to let the highs go through.
The rear Infinity Kappas are mounted directly to the metal rear deck via some brackets made from misc scrap metal pieces. Stock Paseo speaker grills are mounted on top of the rear deck cover.
Wiring is a medley of Stinger 4 guage, Stinger distribution T's, Rockford Fosgate fuse holders, Rockford Fosgate 8 guage, and some off brand 8 guage.
