See I keep hearing mixed reviews on the basslink....
Depends how you define "thump"... I want to feel the bass a little inside the car, definately don't want the car next to me feeling it though. The Mach 460 already sounds awesome too me, just want more bass... doesn't have to sound like im in a movie theater but at least be able to handle bass and feel it a bit.
I was thinking Basslink and a whole lotta dynamat. I went to best buy and the cheapest sub was a 12 Rockford, with amp and install and everything it was over $300... too much.
