okay i got 2 JL 12w3v2 in a sealed box
and a 2 Channel Pioneer GM-5200T amp 380 rms if you bridge it . (i bridged it)

Everytime I listen to my music during a hot day the music isnt loud and my subs don't really hit, they are still on and they work but the sound is very weak.
I open my trunk and my amp is pretty hot.

Later on at night when it is cooler My system works perfect... it almost seem like my speakers all around sound better too...

I know that i need to replace my amp and it is underpowering my subs. But Is this just a crazy coincidence that when everything works better when its cooler? and is my over heated amp causing my speakers to not work as well?

This is pretty confusing.

 

Yes, the amp is in thermo protection. Look into getting a bigger amp that not under powered

 

Ditto the above^^^

Which 12W3v2 do you have, D2, D4 or D6 and how are they wired? 94

 

i have D4 and i wired them in series.
