im waiting for these bad boys to come in-i'll tell you right now they sound ten times better than W7's. i drove all the way to anderson sc to hear them and they blew my mind. i heard them in a 2004 silverado, (sealed-under rear seat) i'll never use another sub. they run at 600 rms but can handle 1200. best sq sub made period!!!! no comparison between the two.

2.DLS IRIDIUM 12"= QUICK-RESPONSIVE, DEEP, LOW MIDS, GOOD TONE, CAN GET LOUD- GOOD LOOKING
