Sean Sinha Posted July 15, 2012 Report Share Posted July 15, 2012 really? i have my low pass filter on my amp at 80hz but does that mean i gotta set my it on my head unit at 80hz? i will try 120hz man You said your HPF was set to 80. If you have your HPF set to 80 and your LPF on an amp set to 80, that's not right. Set your HPF to 120 and your LPF to 80. You can do either. You can either disable the HPF/LPF setting on your HU and have your amps do it all, or you can set it by your HU and turn the crossovers on your amps off. This is especially helpful if you don't have test tones to set your crossovers on the amp correctly. To test, I'd disable the crossover on your amps and set your HPF to 120 on the HU and your LPF to 80 on the HU. See if this cleans up your speakers.

michigancapri92 Posted July 15, 2012 Report Share Posted July 15, 2012 Distortion isn't always clipping ... if you put to much power to speakers clipping or not it can distort them due to over excursion .... just what I think I could be wrong tho Quote Teamcapri.comThe TeamCapri 1992 Mercury Capri XR22012 FORD EDGE SQ BUILDOld build logMy FeedBack1992 Mercury capri XR2 Hyper LED Link to comment Share on other sites More sharing options...
