audiobahn is shiny, not much else, always have been a bottom row jensen type. I like soundstream, pheonix gold used to be great, but has been dilluted down by other companies buying and selling them, PPI is not bad, but again not the same company they used to be. Hi fonics are decent for the price (have their stuff in my bravada) powerbass is a good cheap brand, as is db drive, and fusion.
