Got My Sound System Almost done. I' using the stock Headunit and Infinity
7541a Amp 139 Watt x4 into 2 Ohm Infinity 6x9 and 6.5 Coaxial. Also replace the front tweeters with Rockford Fostage 3/4" 100 watt units. Also Infinity Basslink II 250 Watt Self powered 10" square Sub. And Sony mx-575? 10 Disc Changer MP3/CD (using PIE adapter from OEM Radio).
It sounds great, good tight bass and lots of trunk room left. I do get some "hiss" from the OEM radio at the quietest of setting. but I have it set up for alot of gain !!! I rigged a high/low 4PDT range switch to allow for Ultra quiet when parking/engine off. Check out Attached Pics. Rock On...
