I'm selling the JL 6w3's mentioned in one of the previous posts. They're stout little drivers. If they don't sell one of them will be going in my dash...only require .15cubes each sealed. But that won't be until the spring...so for now they're still available.
my bros running a pair of m6's in his back door on 100wpc and they do pretty **** well. I figure 3 in an enclosure would be pretty good on the right power, wouldnt go over 500 watts
