mrx-v60 issues.

[2007rustanggt 10+ year member]

Hi all first post. Anyway i have an mrx-v60 and it is my current mids and highs amp. Works great till i crank the volume up on some songs with extreme highs. Amp goes in to protection mode and im left listening to my subs only. I think maybe im having a voltage drop issue but not sure how to find out. Havent noticed any dimming or anything and the jetta doesnt have a volt gauge. Does anyone have any idea what would cause this? How to test drop if any? Hell any info would be greatly appreciated! Thanks yall

I have a dmm but do i put the leads on the power and ground of the amp or battery to test this? Sorry im still a rookie when it comes to electrical stuff. Thanks for your quick reply.

Umm... do i need to play a specific tone so i can witness the drop? Or should i be able to see it with music?

I mean u should see drop during normal play but if u feel like it throw in a 1k tone burst and put on repeat and then check voltage that will make it drop for sure.

Ok it was 13.2 at idle and when the amp shut off it briefly dropped to 12.6ish.

So is it the battery? Or is that acceptable and i have a differrent issue?

Have you considered that the amplifier components are simply overheating? How do you have it installed physically?

Can an amp overheat in 10-15 seconds from turn on? Right now both are mounted on top of the sub box in the trunk. I can put some spacers under it so it can car bottom air flow too and put a fan at the front so it gets more air flow...

Also the positive terminal on the battery is pretty corroded. I am going to clean it off today and see what happens

What causes over current protection to kick in? It deffinately is not a car side electrical issue that i can find.
