If you ask me JL Audio is over rated and over priced. I have a Pioneer Premier TS-W3004SPL which is basically the same as a W6 or W7 except I got it off ebay for $130 and I have an MTX Thunder 6500D amp which puts outs 775 watts at 2ohms. I only paid $160 for the amp off ebay. So if you ask me, JL Audio is a waste of money.
