what I'm concerned about with the bass is that with 300 watts per channel (either with an additional 300/2 or a vga800.2) going to each Z6 up front, I need more bass in back to balance the sound.
So I'm open to suggestions on how to fix the bass issue -- I plan on a rear firing configuration, w/ bass venting through the rear deck speaker holes.
according Soundstream, and this was from Karl Cummings:
"We are NOT owned by DIRECTED audio, we are owned by EPSILON Inc., which happens to be the parent Company of POWER ACOUSTIK, KOLE AUDIO, FARENHEIT and SPL Electronics."
Yeah, I'm sure that's real comforting for you, coming from the corporation that offers all those great products, lol. I'd add another JL 300/2 to the components if anything, the newer Soundstream stuff is pretty much crap compared to what it used to be. The JL 500/1 may keep up, but it depends on how much bass you're wanting. You could eventually get an ID Max and JL 1000/1 (or other 1000W RMS amp), or two ID Maxes and an amp that will put out 2000W or close to it, that would definately keep up.
