Well been doing quite alot of reading on this forum and others and have it pretty much narrowed it down to getting either 1 or 2 av15's but not sure if its really worth it. what i mean is i have a 01 civic if i get 2 then im almost positive i have to knock out my backseat and just build a box in place of it cause from what ive been told i need for 2 about 3.5 cubes each and wanted to have them tuned to around 27hz. but if i go one i could prob still fit the one in the trunk no problem. my question is if i go 2 is going to really be worth the extra effort of losing the back seat ? i know this might be stupid but i have gone through many different subs and im tired of spending money and not being happy.
