I have done a little research through the forums and have settled on the things below. Here is what I have already purchased: JVC HDR20 head unit (I know its more on the basic side) AQ1200D Amp Here is what I plan to buy unless there are any objections: 2 X Sundown Audio SA-12's Amp installation Kit from Knuconceptz (Which one should i get tho?) Dash Installation Kit and Wiring Harness Sound Ordnance Bass Bunker Sealed Box with 1.260cubic feet per chamber Do you guys think this is a good setup? I'm shooting for mostly SQ but wouldn't mind a little THUMP. So I have a few questions. 1) The amp i want runs 510X1 @ 4 ohm, 870X1 @ 2 ohm, 1200X1 @ 1 ohm. The subs I want are rated at 600 watts RMS with the option of dual 4 ohm coils or dual 2 ohm coils. Which would be better?
