Sony XPLOD overheating

[tareksnow]

Good day,

I have the below sound system in my car, however, it is always overheating after 30 minutes of use; the amplifier auto shutdowns, if you try and touch the amplifier, it would be extremely hot.

I am a real beginner so please bare with me.

I had a shop install it for me, however, he could not fix the overheating problem.

I was told it may be due to bad tuning.
Also, the amplifier is upside-down, but nothing is covering it.

because you are using a 4 channel amp to power a sub?

maybe think about getting a proper mono block amp to power it.

Never mount your amplifier upside down - heat sinks don't work as designed.

Upside down, although not preferred (and WILL cause it to run hotter), should not cause the issue you are experiencing- You could try to mount vertically to see if it makes a difference, but I doubt it will. That amp is allegedly configurable in a 3 channel setup, but I don't see a manual anywhere. There may be some info printed on the amp itself to ensure it is wired correctly.. Improperly configured the amp may see a much lower impedance (the OHMS) than the amp is built for, which could definitely be a possible cause of your symptoms. Barring that, I would concur that the right amp for the job is best...

never mind- found the manual here: https://docs.sony.com/release//XMGTR4A_EN_ES_FR.pdf

Make sure the sub is wired to L+ and R- ONLY..
And I would turn down the "Low Boost" since the specs read 800W max / 340W rated for the mono portion of the setup..

Good Luck!

With RCAs red is right so that makes black left. Your setup is 2 fronts, 1 sub. So the subs are getting left only and the front is right only? I also agree with removing the 40hz low boost. It looks like it's set to half way. Also the gain on that left side looks like it's either at MAX (bad) or at 3 volts which is ok. It's at max if you cannot turn it clockwise anymore which could explain why it's overheating. I suppose one quick thing you can do is disconnect the two black RCAs which runs your sub and try again. If it still overheats, you can turn down the gain on your fronts, let the amp cool and repeat. Don't be too worried about changing these settings. You took a picture so you can also dial things back.

I'm surprised that the place you took it to didn't see this. Seriously, even the females in my family know how to attach the right RCAs. I'd take it to another shop.
