Amp rack necessary/desirable?

[skimo 10+ year member]

I'm installing an amp beneath my rear seats and the short self tapping screws that came with the amp won't reach through the thick insulation beneath the carpet. I'm wondering if I should just get longer screws, or should I mount to carpet covered piece of MDF and screw the MDF to the floor with long screws.

Is it a good idea to mount the amp to something solid - or does it matter?

Thanks

you could get longer screws and mount the amp to the frame under the seat. you dont really need wood to mount it to first if the surface under the seat is flat enough. self-tapping metal screws should work fine to hold it down.

I would personally go the wood route. First, you need to electrically isolate the amp chassis from ground. Second, were the amp to heat up you now have melted carpet. Screwing amps directly to the car is just not good install practice.
