Sony MEX-1GP getting warm

Hey, hello everybody!

I have a Sony MEX-1GP car player with 4 speakers (3-way 60 W), and around 20 minutes with a MP3 playing, it get too hot (can't neither touch the heatsink) making the sound volume decrease 'til no sound. Then if I turn off the radio, wait some minutes and turn it back on, the volume came back. What should be the problem?

Thanks!

Hello, pbabin! Thanks for answer!

I have to agree with your last comment... I should use an external amplifier to solve this problem... but by now, I will try to use only 2 internal channels (2 front speakers)... let's see if it works!

I have the same problem.

It's common for head units to run extremely hot when driving all 4 channels from the internal amplifier. If you can get some air flowing over the heatsink, it will help greatly. The smallest fan you can find will move enough air to reduce the temperature significantly (assuming it's placed where it can be effective).

A better option would be to use an external amplifier.
