I'm not sure the actual terminology, ive never really experienced it until now... But if I push my system, the power cuts off, the stereo restarts when a loud sound hits. I dont often push it so I havent worried...until installing the new head unit.

I can lessen the issue by turning down the input device(phone)

system is not huge....

the Sony DSX-55 I Just put in.
running two Kenwood speakers.
Then, a JBL MA6004 one channel running two pioneers, the rear bridged for a 10 inch RF sub.

how would I go about troubleshooting that? I have had decent stereos before not had this issue........

i have power direct to battery, but ground through the boats ground... should I run a wire straight to battery negative? thinking out loud... I mean for the amp only....

Definitely ground your amp directly to battery that the amp draws power from. Also be sure your running a large enough Guage power and ground wire. That could be the problem as well or may not be big enough under heavy load.

This could also be the problem. Your running "2 pioneers to one channel". How are the pioneers wired? Series or Parallel? Those two could be dropping the ohms of your amp down, and therefore overheating the amp under heavy load
 
I think you mean the pioneers are on two channels? Like 1&2 running pioneers, and 3&4 bridged to sub

sorry. Im only half dumb. not that bad lol

theyre not linked. its a 4 channel amp. two pioneers using the front TWO channels. REAR is bridged to one sub. all well within spec.

well i needn't have typed reply, you saw through my 4th grade typing skills. lol

I'm thinking its the head unit... the amp doesnt seem to shut down independently. it's on its own DIRECT higher gauge fused wire to the battery. But the SONY is wired to the factory wiring... the ancient head unit i took out of there was definitely not knocking out that much wattage lol

but they share ground... so first Ill run a better gauge negative to the battery to eliminate that..

I feel like Ive been thinking incorrectly...the HEAD UNIT shuts down.. the amp only shuts down, im assuming now, because it loses its remote turn on lead? And, I dont think the amp losing power would affect the head unit...it would stay running just shut down the sub and pioneers...

so I'm going to try disconnecting the (non amplified) Kenwoods from the head unit, turn it up. see what happens. that should tell me immediately if its the OEM wiring. Or a short with those speakers... At least I would think.... because, It did this before with the Pioneer CD player i just took out. Just not as much.

If that's still the case, Would it be wise for the head unit to share power supply with amp? Or run another straight to the battery for the HU?

thanks for the replies... this is one of those fun problems to have... :)

The amp cutting out could indeed be from the head unit powering off. Head unit powers off which in turn cuts remote wire to amp which cuts amp. Easiest test would be disconnect amp and try head unit only on the Kenwood speakers. Turn it up. If it cuts out its the head unit. If not connect amp back, and test again.
Definitely one of those problems that's going to require trouble shooting. My guess is ground issue with amp or head unit. Or faulty head unit. I had a old head unit did that alot. Replaced unit and no more issues
 
Also wouldn't be a problem at all for the head unit and amp to share a power supply. Head unit doesn't draw alot of power anyway. So using like a distribution block can easily be done
 
disconnected kenwoods from head unit, it hits pretty hard, no shutdown. so ill clean up the wiring, maybe replace them and/or the speaker wire.. :)
 
update:

it was indeed a weak factory ground wire to the helm. they are NOW grounded together, I ran a heavier gauge wire and the thing bumps. I added baffles to the back of the Kenwoods too. protection and a little more low end.

thanks all.
