Well I tried to just take the package tray off. It still shut off the amp. So now when I get the chance I am going to try what BlueShark said and get a thin board and cut the center out of it for air circulation. Also Im going to try adding a fan at the top that would blow the air under and over the amp and see how that goes.

 

what are the exact specs of your subs and amp?

 

you might just need a more powerful amp. it sounds like you are maxing out the power of your amp. you could try a one bigger amp or two smaller ones.

***edit***

are you running anything else off that amp?

 

Here are the specs:

AP California amp AP1000M
RMS Output Power (4 Ohms) - 310W x 1
RMS Output Power (2 Ohms) - 500W x 1
Peak Output Power (2 Ohms) - 1000W x 1
MOSFET Power Supply
Pre-Amp (RCA) Outputs
Signal / Noise Ratio - 103 dB

Infinity Reference 1030W 10" 4-ohm Component Subs
Power Handling - 250W RMS, 1000W Peak
Sensitivity @ 2.83V/1m - 88dB
Frequency Response - 25Hz to 400Hz
Impedance per Voice Coil - 4 ohms

I have the Subs wired to create a 2 Ohm load. I just have the subs running off the amp, nothing else.
