I've just installed the following Alpine equipment and I'm having a problem with the subwoofer missing the beats, and sounding a split second after it's supposed to.
Alpine 9833R head unit (no time correction applied, only some EQ adjustment)
Alpine MRPM650 mono amp
Alpine SWR1242D Type R 12" subwoofer
Power cables are 4awg.
Any suggestions what this might be? Perhaps Mr Coo can suggest something obvious... I did wonder if the sub having the wrong polarity wired could do this.
