Help needed on cooling fan/solution

Hey gang,

I have an Alpine PDX5 installed in the stock driver side location in the trunk, powering upgraded speakers in the car via Technik's pnp harness. When I play a very high volumes for a few minutes, the amp goes into thermal protection shutdown.

I'd like to avoid this scenario, and of course play my music loud, so I'm thinking of cutting some cooling slots into the plastic cover of the amp recess. But I'm wondering if passive cooling slots are sufficient, and was wondering if someone could advise on the matter.

If I should buy a fan, what's the smallest, simplest and most reliable recommendation from the collective?

Or am I simply overdriving the thing, and I should turn it down a notch?

Many thanks, appreciate your thoughts...
