Im looking for a new HU. It's defiently going to be an Alpine. Im just not sure which model to get though. I want to be able to adjust my acoustics/bass to more of an extent, instead of just the regular bass/treble settings. A mp3 player would be a nice add-on, but it's not a necessity. Also, i dont really care for a wireless remote. Pricewise, I'll be looking at $100-400. Any help on what model to get would be great.
