My stereo Install.
I got a Rockford trunk (i.e. sub & amp, which is a 300s -Pilot like remote punch bass-), A/D/S doors & dash (comprised of 5.25" & 4" 3-series components) which are powered by a 4ch PQ450 A/D/S amp (also in trunk) and then the Alpine 7893 up front. I really like the system. Cost a pretty penny, and took quite a while to assemble all the parts. But for an audiophile who likes to crank Maiden it's well worth it.
check yah later
Although as long as your completly flush the system you can use the newer coolant in older Audis.
