I just got a JBL GTX 10" 450 watt rms subwoofer from the local pawn shop for $20. ive never owed a jbl and know nothing about them. this seems to be an older model as i have only found it on some canadian auction site when i googled it and thats it. any one have any experience with these and/or know if theyre any good or if i good a good deal. the guy on the canadian auction site wanted $100 for his so i figure thats a good sign.


heres a pic i found online that lookes like the same one

Also i currently have a type r 12" hooked up would adding a 10" be a good idea for better SQ. my logic is that a 12" for deeper boomy bass and a 10" for tighter bass but idk i could be thinkin about it all wrong
