I took off my old setup about four months ago. I had a piar of 12" Kicker CVR's in a ported box powered by two channel Performance Teknique amp. It was pretty cool but a little too much for me and waaay too heavy - 80+ lbs. So I had another Performance Teknique amp (ICBM-774) hooked up to a pair of Kicker components and a pair of some 50w pioneers (they were in the car when I bought it). Anyway, as I said, I've been driving around with that for four months BUT I had my old 12" S12L5 Kicker sub in a sealed 1ft^3 box laying around my room. So I said screw it, I want more base and decide to connect it to the current amp. I wired the sub in 2ohm (DVC 4ohm) and hooked it up to one channel (!!!) of the amp, so it's receiving about 150W rms right now and OMG!!! DOES THAT THING BUMP!!! The little crappy amp is worth every penny I paid for it! The Kicker rocks too! Not even sure if I want a separate amp for that woofer anymore

Just thought I'd share this

 

nice,....my lil bro just got a 93 celica so over the weekend I put my old Kicker 12" Solobaric(round)
in a 1.2 cu/ft box i had , and powered it by my old Soundstream SA120 (180 rms bridged) and it knocks!! Amazing how with lil power that thing got going- and because the car is so small the in cabin response is pretty insane
