Recently I had a 125.4 FSD amp go bad on me, terminals 1&2 went bad. Replaced that with a really nice zapco (about 1 month ago), hooked it up and up until 2 days ago I had no issues. Between vol 16 and 26 (26 is max I play at), channel 1 & 2 turn on and off, then it continues to ch 3 &4. Rear speakers still play but it sounds like someone is plugging and unplugging speakers. Bass does not skip a beat.
The last thing I did was rewire ch 3&4 thinking the wiring was the issue just before ch 1&2 on FSD took a dump. Since the recent issue, I pulled my HU (Pioneer NEX) and rewired highs & lows remote wire as it was 3 pieces in total. Re ground HU at chassis, clip and trim ch 1,2,3&4 on highs and open all 4 door speakers to make sure I have good connection.
ZAPCO 180x4 (forget model number)
saz1000.1
sundown shallow mount
2 ID xs69 in front
2 pioneer 6x9 5 ways in rear
Pioneer nex
XS D3100 under the hood
mechman HO alt 270
knukonceptz RCA for highs and lows.
Big 3
This is doing my brain in... anyone have any tips, recommendations or things to test/look at?
Much appreciated!!
