I'm going to get the iva-d310. mostly for it's ipod simplicity and the new alpine nav software coming out this summer. I already have an A/D/S/ PH15 (6ch 300w)and a couple of 8" JLs in a rear firing box from my 16v GTI. they are 10 or more years old but the A/D/S/ amp, i hear, should still be pretty good. I'm not trying to do this on a budget really, but i'll use the ph15 if it'll hold weight against other newer amps. Do you think this amp is ok for running a set of dynaudio components up front and the subs. i don't know if i'll put anything in the back seat yet, probably keep runnin the factory speakers for rear fill. I want a well rounded system. not insane bass and not too much highs either. I don't know, what advice do you have on my setup so far?
