This is a complete blue thunder package, a complete pro-audio set up. Because off the way car audio used to be where all the tweeters and mids and bass was a package deal has to be hooked up in a suv or where you can drop the seats and have it aimed at you. This can even be hooked up in the house because the sound is the most amazing ive ever heard. This is a collectors set up so im gonna have it at a price that is worth it ive seen the 10" woofer alone go for $200 bigdwiz had these on his channel and talkes about the rarity in this mint condition. The price is firm or ill leep it in my collection. Cash sale final upon purchase. Also where you hook the speakers up in the back off the box are breadboards that pull out and have huge crossovers built in with glass fusing. Thanks for looking.
