So my first thread became inaccessible? I has no permission to view. I own a 1995 Ford taurus with stock electrical. I'll only have this car for few more months. My setup was Alpine CDE-153BT; kicker Ks 6.5" Fronts; Kicker Ks 6x8s in the rear deck; and a Sony XM-GTX1852 bridged for my sub amp (rated at 400 watts @ 4ohms only, it is not 2/1 ohm stable). My old subs were 2 RF P1S2's in a sealed enclosure. Now for my question... I got rid of my subs for some extra holiday cash as my debit card inconveniently expired a few days ago. I get a new one on the 28th, and would like to order a Sundown sub. Ive become a fan of sundown after hearing that beast of an SA-12. I don't feel like Id have the power to make an SA play yet but idk for sure. Ive looked at the E 10/12 and Sa 10/12, in a vented enclosure. I has teh wood working skills and equipment to even do a horn ported if I wanted. But, ultimately? Which sub? Enclosure ideas? In trunk? Or back seat? I'm wanting to maximize SPL while still retaining decent musical SQ. I understand the lack of power but there's not alot I can do with this car. I'm not touching the electrical. I'm getting an 01 GMC JIMMY come tax returns, that ride is for the big boy pants build. Edit: Amp does truly push 400 RMS or very close to it.
