I'm looking to pick up an 8W7 to see how it sounds, and I came across this garbage:
http://www.sonicelectronix.com/item_4198_JL+Audio+8W7-3.html#tabsOne of my friends had 2 of these subs in the trunk of his taurus, and he had two 800 watt jl amps to them, and he chalenged my friend with 1 Kicker comp 8" subwoofer connected to 1 250 watt Kicker amp and the Kicker blew the Jl away, one of the Jl 8's cone even started to fall apart so he had to put apoxy on it to fix it until he could afford another one, so if you want a good loud powerful 8 for way cheaper than this one get a Kicker
