I have a 10in W3V2 (version 2... the newest model) and a stealthbox that fits in the back trunk space for firebirds and cameros only. if you are a young buyer and just got into car audio this is a very good choice. i have had the box for about a year and it is in pristine condition and i ordered a brand new version 2 w3 10in sub from the factory. i have not used the sub at all since it has come back and i must tell you the version 2 are extremely great in firebirds and cameros. when i first bought it i thougt that it was not going to be that great but when i was installed i was surprised. many people thought i had 2 10's or an expensive system which i do have now since i upgraded some things in my car. if you are just thinkin to find the best bang for your buck in a box and sub this is it... brand new is around 450- 550 for the box and sub since it is the new version... I AM SELLING IT FOR $$$$350-375$$$$ i will talk down most likely in the price if you e-mail me... i got into a not to back wreck with my car so i really need the money.... if you would take this off my hands i would really appreciate it, Mitch ***my sn on aim is mak1671 if you are on for any reason for this***
