Lets See. I just bought (2) Alpine Type R 12" speakers and a box to put em in. And, an Alpine MRD-M301 amp to push em. Now, I can listen to heavy stuff or bassy stuff with a system in my car that DESTROYS. Recent albums that sounded good in it:
Immolation: Harnessing Ruin
God Dethroned: Lair of the White Worm
Krisiun: Bloodshed
Also, a good Rap album was:
The Game: The Documentary
Mobb Deep: Amerikaz Nightmare
