well, i've liked two brands, and that is pioneer and sony. before you rag me on the sony let me just say the f7715x is one of the best hu's you can get for the money EVER and there is NO debating that. 24bit burr brown dac, 3 4volt preouts, great sq, pause function, plenty of MP3 settings, looks great. And will last through WW3. Fantastic HU. probably the best they ever built, best anyone ever built for the MONEY. i miss it already. (i can see it fright now if i turn my head right and look up)
And my plenty of pioneers. Let me also add, the only reason they broke down is because of my many wrecks. I remember one paticular wreck (with my 4600) the cd player shot out and was only saved by its wiring harness, it lived to play for a long time. When i finally dropped the face plate enought times on concrete (atleast a dozen times) the lcd broke and i couldn't see shit. but it still played just the same as before. Fantastic units.
