Question Car audio

[Johnsjos021]

After a while of playing music at a relatively high volume 25 of 35 on the head unit sometimes the speakers will sound a little disrupted and choppy, it goes away if I turn off the car and back on again. Any reason why this would happen ?

What's the make/model/year of the car? Is it all stock audio or any aftermarket?

It's a 2002 Nissan maxima, it has a kenwood kmmbtu 225u head unit with Rockford fosgate 6.5 door speakers in the front doors the back doors have 5 inch Rockford fosgate speakers, I also have a 10 inch all in one underseat subwoofer from Rockford as well

If it's time based it is either overheating or an alternator that can't keep up.

Likely the head unit internal amp is getting too warm. I assume the head unit is powering the small speakers, and the all-in-one has it's own amp, and you don't have any other amplifiers dedicated to the speakers or anything.
