Recently purchased an 06 RTL. First things first, stock system has to go. Upgraded the head unit to a Kenwood X693. From my previous car, I have a RF Punch 600a5 (yes, old school!) that supposedly will hold 200 W rms to the sub channel at a 2 ohm load. Unfortunately my JL 10W3D4 sub won't fit behind the rear seat, so I'm looking at shallow mount subs. In searching ROC.com, I see a lot of people are buying the Elemental Designs SQ10 and, by and large, are very happy with the performance. Now, I know that a higher price doesn't necessarily mean higher quality, but the price of the SQ10 ($110 regularly, now $70 on sale) raises a bit of suspicion when I look at other 10" subs and the prices are $130 and up. Granted, those prices are from Crutchfield (convenient search) and they're a little inflated, but still, the ED SQ10 would land $15 cheaper than their least expensive shallow mount sub from their outlet. Sooooo, what's y'alls take on the SQ10? Is there a catch? How's the ED going to stack up when compared to the JL that I have? Does anybody have any suggestions for other subs that will outperform the SQ10 if I’m willing to spend a bit more (less than $200), or is the SQ10 the shiz in that price range? Thanks!
