Better be careful on 64 with all the damn potholes and stuff you could end up airborne.
I have on 05 and got rid of my shaker 500 3 yrs ago.
Replaced the Shaker 500 head unit with a Pioneer AVICZ 920 bt.
All speakers subs and amps are Memphis Audio. Front door sub and speakers were replaced by a pair of MCC8 Midbass component speakers, the tweeters were removed and custom mounted where the door speakers used to be. The rear speakers are now a pair of MC 692 6x8 (or 9 can't remember). In the trunk, two 12 inch MCP12D4 subwoofers in a custom box. For the Amps I have a PR 4X50 and a PR 1X1000 mounted in the trunk in a false floor where the spare tire used to be.
The sound quality with the Memphis Audio gear is absolutely amazing.
