[QUOTE="drpeeb, post: 5926298, member: 609183"] Just installed a PDX-5 amp (75Wx4 RMS + 300Wx1 RMS), one SWS-1043D sub (4 ohm DVC, 300W RMS/ 900W max), and a pair of Alpine SPS-600 coaxes. I'm running an iPod Nano straight into the amp via a mini-to-RCA cable with a splitter at the end of each of the L and R channels in order to feed both the front and sub channels. With the amp's gain at zero, I can't even get close to the speakers' distortion level ... They have plenty more power handling capability left in them. Cranking it nearly all the way, say 85%-90% on both the fronts and the sub, seems to be a good match between the iPod's volume range and the speakers, i.e. With the iPod's volume nearly all the way up, the speakers will be just approaching distortion. I'm guessing this means the iPod's output is under driving the amp? Will I hurt the amp with its gains set at 85-90%?? [/QUOTE]
