pioneer amp problemo!

[chrisw91 10+ year member]

have a Pioneer Stage 4 PRS-D4200F 4-channel car amplifier — 75 watts RMS x 4 at Crutchfield.com in my truck and having some trouble diagnosing why it is cutting out. not sure what to blame here... have only the front channel hooked up to a set of components, and have another amp set up through the pre out rca's. when subs hit, the speakers from the pioneer cut out, but the other is still going. so i thought maybe vibration damage... but even when at low volumes without subs not playing, when i take a hard turn on the road they cut out, or even when braking hard. is it possible something is so loose in it that it is that sensitive? ground? but wondering, if that amp shut down, would the pre out still feed to the other amp? want some help here as it takes 3 hours to get to the amp... thanks

Check all your wiring connections. When it cuts out is the amplifier still on lit up? if so it could be a short in the speaker wire. If it turns off when it cuts out, its either a loose power or ground wire, or a loose turn on wire.

everything seems good! speakers are 4 ohms, ground is .3 ohms, lights stays on but after i heard them cut out i paused music real quick and i could here something in the amp clicking like its turning back on. but never saw the light turn off...
