just purely imo, but taking the rlp over the tc3000 is like saying you'll take a blazer over a escalade because your garage is slightly too short for comfort for the escalade even though they are the same price...
honestly man, the rlp is worth its price, and the sq is great and all but from a extra value stand point, the tc3k right now's sale is pretty crazy and being that they are the same price, i'd try some how to make it work in your set up, its a pretty deep sub but unless theres no way in hell to make it work, then get the rlp...
