i already purchased the new alpine v 1000 amp. very clear sounds and i also have the 1023 a 923 and 2 723s. i dont have a budget in mind i just want the best sound i can get without being 2 outrageous. ive had a new pioneer with ipod connection they are good but have too many functions for the sounds.and the volume menu button goes funny i prefer alpines older units and sony. what do you power your audiobahns with?
