I'm looking for opinions on a 10" sub for my 2000 Pontiac Formula. The enclosure will be a sealed stealthbox in the left side of the rear hatch and be approximately .6 cubic feet. I'm looking to power it with an audiopipe apsm-1500 or apsm-2000 @ 4 ohms. So that would be approximately 600 or 900 watts rms. I was looking at the re audio SE X v1 and also the psi platform 1. Any thoughts or opinions would be appreciated. 6.5" maximum mounting depth preferred. Budget no more than $300. I want a combination of sound quality and spl (sql?). Thanks.
