Hifonics amp seems to be hitting less? how to check..

[face_reality 10+ year member]

I have a hifonics amp and it seems to have dropped some... it just doesnt seem to be hitting as hard or as loud as it did a few months ago... how can I check to see if something has happened where its not pushing out the wattage it is suppose too... or is it the subs? did one of the voice coils go bad or something.

Anytime my sub ever went down in output it was a blown coil or torn tinsel lead, take a DMM to the terminals on your box and see what the ohm load is

I havent changed anything from when i installed it subs are at a 1 ohm load to the amp because the amp is 1 ohm stable...

You're getting less voltage now that it's warm out.

whats worn out the amp or the subs? whats the lifespan of each then? I might check the ohms maybe a voice coil went bad than would change the ohms if one of the coils go down wouldnt it?
