[QUOTE="DRBOOM, post: 8765625, member: 676005"] 2 volts is not much but I also try this: Get a 3.5m jack to RCA and plug into your amp. See if you have the same issue. Secondly, you may need to take your subwoofer out to check if any wires are not loose or causing the clipping, by grounding. Also many amps are mixed ratings and specs, and even the days of testing power today is now calcuated at 14.4 volts, and not 12volts, ( which in my opinion provides more accurate specs) and also the signal to noise ratio on the amp is another factor to take into consideration. (My old PPI PC450 has a s/n at 110db and damping factor of over 500 but such details are not important with the new gear. Speaker sensitivity is another factor or if low voltage goes in from RCA's and speaker sensitivity is low, then you will have a lower output as well. If you are still not happy after all this, then maybe time to upgrade to a better head unit. I know for a fact old school gear had high voltage head units which provided stronger signal to the amps so the amps performed better with lower gain settings. Win-win situation. Good luck with it mate and let us know how you go. [/QUOTE]
