At the moment I am running some mid quality MTX to show how good things can sound with out spending a lot of money.
I have in my subaru
TX6001 (Bi-Amped)
TC4004
TC4002
SLHT-TC712 loaded
Eclipse CD7000 headunit running in 3way mode.
In my nissan
MTX 7804
TXC.6 components
MTX7500 12"
Eclipse 3590 doubledin Nav
custom enclosure
Very simple but pure SQ.
Let me know because I can help you with the wires, speakers, sub box, and other things when you are interested. and the wires are Streetwire’s and you cant get better then that.
