I just traded rides. I had a '95Trooper with Polk dB stuff throughout. Also, Phoenix Gold, Audiocontrol, Kenwood eXcelon.
My 2 Polk 10's were slot-loaded and driven by a Phoenix Gold PG2500, bench tested at about 650 Watts. My daughter is going to get the Trooper at college (she's happy).
But, I am considering splitting up the Polk 10's and putting one in each car. I am thinking about using the PG 2500 to drive the single Polk dB 10 in the new Envoy. It has the new Bose system in it ,which sounds amazingly good for a stock system.
What kind of enclosure would you recommend for good SQ. I am into accuracy of bass. I am thinking about slot-loading or down-firing the sub for sound quality AND to protect the sub in my SUV. Gotta have those golfclubs in there.
