alright most of u all know me. i used to have 2 12w6v2's runnin off a 1200.1 and now i have just all upgraded speakers amped up. Well honestly....i cant tell a HUGE difference between unamped and amped speakers...so im thinkin about using 2 channels on my amp for all 4 speakers and using the last 2 channels for a sub. I believe its possible to just bridge 2 channels right?? i dont want to bridge them all...just channel 3/4. If i bridge them...i get 340 watts at 4 ohm. So id be looking to get a sub that will run good off of 340 watts at 4 ohm. Obviously im not going for all out SPL here....since im only running 340 watts to 1 sub. Im looking for the best SQL sub out there for my situation. Also....I want to keep the cost as low as possible. I will look at any size sub...including 15's if ther is anything that iwll work good with that little power.
