I had never heard of boss before buying this. i'd always heard about kewwood jvc kicker etc but i saw these and figured i'd give it a shot,

amazing sub, hit really hard although it did end up blowing after 3 weeks cuz im an idiot...

don't push a 4000w on a 2500w sub ;) bad move there. none the less ordered another one because this sub is amazing!

my only advice is when getting a new sub follow the setup instructions to a t. make sure your grounds posi's leads and everything are 100% perfect don't half ass it you will regret it later (nearly had a car fire) and seeing as it's new equiptment make sure u kinda break it in. get like 10 hours on it just smooth light to medium bass before beating the hell out of it
