99kustoms Posted July 18, 2013 Report Share Posted July 18, 2013 Hey guys, just got done trying to set up a Alpine MRV-F300 which is Alpines "mid-grade" 4 channel Class D. HU= older Pioneer but no clipping until MAX volume was hit. When I was agjusting the gain, I couldn't even nudge it off of minimum without the DD-1 showing clipping/distortion. Is this a common thing with the Class D full range amps now? I also tried a couple other full range Class D amps and still the same result. I then tried it on my T4000 Fosgate amp and it worked perfect so its not the DD-1... Quote Link to comment Share on other sites More sharing options...

RooTxBeeR Posted July 18, 2013 Report Share Posted July 18, 2013 class d amps are less efficient than other types. they also hit 1% distortion faster, so busy mess around with the amps. also do what snowdrifter said. you sure your using the rights tone tracks too?

99kustoms Posted July 18, 2013 Author Report Share Posted July 18, 2013 Using the 1k HZ with -5db I have been turnig down the radio and then tuning the gain but haven't had this problem until these Class Ds. Not to mention its rough when custy's turn their system up to max even when I tell them to not turn it past ** number or else your speakers will blow So basically just expect this with the full range class D?
