Amp

[Spike0358]

I have a Pioneer gmdx 971 amplifier pushing 2 skar sdr 12 dual voice coils in the loaded ported box. All is at 1 ohm. They sound amazing until after I got them broke in good, now they play fine for about 10 minutes, then make a funny sound while they cut out. Then after a few seconds come back on again. They only do this at a high volume not max. My amplifier is going into protect mode when this happens. I called tech support, they said I need to use better power wire, got cheap stuff, or not grounded good. I also have it on a 2.0 capacitor with voltage readout, its staying above 14.v This is in a 2011 Silverado with a optima battery, with 4 guage cheap power and ground wire on a 150 amp circuit breaker. My stock alternator is 140 amp. Please whats going on? My head unit is pioneer 1400 nex. Is it the cheap power wire? I have it grounded on a bolt also. I do believe the amp is fine as it plays at low volume fine.

Get rid of the cap, switch to 1/0 ofc, check all grounds are tight and clean. Big 3 too

Ok Ive already done big 3, going use welding wire 2 guage, is that sufficient? Because looks like anything bigger than 2 guage wont fit in the terminals of the amp

Is it 2/0 Or 2 guage welding? 2 guage welding is the equivalent to 4 guage audio. Should be fine. You could also get reducers

Or would this be better

I would go with what’s cheaper. The knu Audio stuff may be more flexible But I’d you’re not doing figure 8’s and shit you’ll be fine. Remember that welding wire is what actual welders use so it’s not junk. 2awg welding eill be the same size as that knu 4 guage.

Ok Thanks

Bad ground, my voltage went from 14.4 to 15.6
