ok i'll try to answer what i believe you said in the first post. first of all, how much $$ do you have to spend on the subs, second of all, im just making sure; you have a HO alternator right? because you cant push 3000w RMS w/o one.
a HO alternator is a "High Output" alternator. And Glasswolf THE audio man has informed us that since solo's are square, they have uneven stress points. There's alotta stuff you should know before you buy this stuff, IM me on AIM: blindc1rca.
a ho alternator is a high output alternator. it doesnt matter how powerful your amps are if your alternator is to weak to power them. with 3000 watts rms, wich is alot then you will need a powerful alternator and a good battery. the solobarics are loud vut the sound quality is not very good there are better subs for close to the same money tell me your price range and i will make recomondations also tell me how many subs you want.
