I recommend the Alpine IVA-205. When i bought this I heard nothing but good and im astounded with mine. It has 3 pre-amp outputs (2v) and the best search feature any DD HU has to offer. Go to http://www.alpine-usa.com/US-en/prod...model=IVA-W205 for more info. I strongly recommend it, you can find it some places for $600.00
