If you're going to believe those zealots at the car audio forums around the net, you would end with something like:
- For Speakers: Rainbow, Diamond Audio, Focal, CDT Audio and some.
- For Amps: Genesis, Sinfoni, DLS, Brax, McIntosh and other even more obscure brands.
As for myself, I began, like almost everyone else, with stock speakers an a Pioneer stereo and right now have three Genesis Amps and plan on buying a pair of Focal Poly Kevlar 165 K2P. For subs , two JL Audio 6W0s and the real fills.. well that's not yet decided.
