I have many different comanies to go with. I can get Cyclone Audio, Crunch, Blitz Audio, Visonik, Kole Audio, SPL, Power Acoustik, Lanzar (Heritage,Vibe, and Optidrive), Pioneer, Pyle, Digital Audio, Profile, Linear,Phoenix Digital and Hifonics all at cost. I have been out of the car audio relm for 9 years and I remember some of the Companies out there. The bad thing is that I don't know squatt about these companies. All the input I can get will be great.
