Customer already had Alpine Type R's installed throughout the cars stock speaker locations.
He had to retain the stock JBL system though, to keep his OEM woofer in the rear.
Well, he picked up a Pioneer 4 Channel Amp as well as a Kenwood Mono Amp.
Goal was to get all the amps installed and mounted, as well as build a custom OEM-style box to fit in the stock location; all while housing (2) two 8" Digital Designs 308 woofers.
After the amps were wired up, I got started on the box...and with only minutes to spare, finished the install by closing time! Alot done for one day, but it sounded good and was worth the extra effort.
The woofers are getting about 250-ish watts rms a piece. They are more efficient in a ported box, but for the space we had, a sealed enclosure was all they were going to get.
Right now, the amp is turned down for break-in purposes, but in a few weeks we can turn it up a bit and let them hit.
Turned down as they are, they provided some pretty low notes, and the mid-bass was much better than the stock JBL system.
