High pass filter is for the mids/highs speakers and its not under the sub settings. Its a regular audio settings option. The low pass (its not called that) is in the sub settings, its the option where u can select 50,80,125hz to be played to the sub.

yea there is a high pass filter on the audio setting of the d2. The low pass (not call that), is in the subwoofer settings under on/off and reverse/normal settings. The settings on the unit or amp arent the problem... the only thing i can think of is maybe the preamp output is bad... i was trying to see if anyone else has had this problem.

Yeah i can turn the sub on and off no problem through the d2. I've messed with all the options on the d2. THe hp is set at 80 and the LP on the sub settings is 80.

It's playing at 4 ohms. I've had that amp sub combo for 2 years, never a problem until i got the d2 a few weeks ago. Signal sense... no

Ok ive had the D2 for just a few weeks and i'm having issues with some sound to the subwoofer. Here is what i have: Pioneer avic-d2 Alpine mrd-m1005 Alpine swr-1521d Ive checked all the wiring inside the sub box and everything else i can see. I havent pulled out the d2. Basically the sub seems to cut in and out a low volumes and sometimes the bass rattles and just sounds terrible. Ive had the sub and amp checked and there's no issues there. I was wondering if anyone has had this problem or have heard of it? Any suggestions?
