The head unit is a Alpine CDA-7893. And the spekers are old aftermaket(Sound advice I think) 4x6 in the dash and the firebird premium setup in the sailpanels(Stock 4x6 and a 5.25). Just recently when I have been driving around. The Head unit would turn off for a second then come back on. It only dose it when I have the voulume at 25(I geuss that's high. The speakers sound like crap after that.) or higher For a few minutes. But it get's anoying. I cant hear the radio with the tops off and the exhust while I am crusing down the road. I don't what's going on. I hope you guys can help me. Thanks in advance for all the help! Adam :-)

 

Start by checking the wiring. How are the connections made? If it's twist-and-tape get under there and make then right.

 

Everything is still criped and heat srinked. It only dose it when I turn it up loud. I can drive allday with the volume turned down and it won't even hiccup. Thanks. Adam :-)

 

Got an ohm meter. Sound like one of the speakers may be crapping out. Check the resistance of all four speakers. Also don't forget to check the wiring behind the speakers.
