Re: >>>Engine whine and ground loop fixes... take two
you just saved my radio and wallet. the old pioneer 4100ub thanks you. got a little ballsy today and ran my dual 1 sub in parallels on my q4.150 rears with the LPF. it didn't protect but in those 7 or 8 minutes my amp got hot as a ***** in heat so i cut everything off and let her cool off and ran every thing back to normal and as soon as i cut on my deck with volume at 00 i was getting awful engine and electrical squeals and whining. thought screwed my amp up back ran a 3.5mm to rcas from the iPhone and noise was gone. popped out the head unit and barely tapping the rcas could trigger the noise. grabbed a random piece of 18 gauge i had slid it between male and female rcas and as long as i physically touching the other end no noise at all. after reading this sticky i will be doing it correctly in the morning.
EVEN IF YOUR 2 OHM STABLE 4 CHANNEL WILL PUSH A SPEAKER AT .7OHM DON'T OR ELSE INCONVENIENCING ***** LIKE THIS HAPPENS. Lesson learned.
