I have some ****y headunit that was in my car when i bought it and im waiting to get a new headunit but right now my headunit will shut off if i play my speekers loud then it will come back on somtines its just for a second or sometimes it takes longer for it to come back on and i just put in 4 new alpine type r door speekers today and i havent even listen to it yet because my headunit wont come back on, so if you know what is wrong and if you could tell me how to fix it that would be really great thanks

 

welcome to the forum. check for loose wires in the connectors (may have backed out) be sure the fuse are good. and ground for the speakers are good & clean.

 

it sounds like a loose wire hitting metal recheck all your work i remember somebody with a similar problem it was the terminal on the speaker touching the frame.

 

If you are not able to find out the problem then its better to take your head unit to the mechanic and get it checked.

 

Well is the problem solved or still there.do tell us ,then we can guide you properly.
