85 rx7, 5.0 from a 95 stang, 289 hipo heads, hei dizzy, b cam, msd ignition, full roller motor, and a bunch of smaller things. Blast to drive, especially with the 3.93 gears(2nd gear launching goodness.) Isn't bad for hauling things too.
I got the sub and amp free and it stays low volume. Used that amp because it was the most efficient I had access to, and used the sub because I know if you aren't pushing it hard it doesn't sound horrible.
My front speakers are a decent set of components. I don't drive around blasting **** and the sub never sees anywhere near its max volume.
