ok i have 4 re se 15's powered by two aq2200ds strapped. the se's are taking maybe 3000 watts of the possible 4400 from the aq's. is it worth upgrading to better subs to maximize bass? my re se's just arent cutting it but, i dont want to spend too much money. also i want to wall it but thats impractical if its just behind the middle seats right?
