Hey guys I am installing my Alpine MRV-T320 amp under my passenger side seat in a 99 civic ex 4dr. I am wondering what type of screws I should use to anchor it to the foor?

Also is the seatbelt bolt point a good place to ground the amp with 8 gauge wire? I will, of course, scrape all the paint/primer off of the bare metal first before grounding it.

One other thing I might have issues with is the floor vent under the seat, during the winter time will the amp overheat if i have the foor vents on with the heat? If so i was thinking of blocking the vent off with some plastic and using some epoxy to attach it.


Thanks for the help!

 

You should use no screws to anchor it to the floor.

You should cut a piece of plywood or MDF slightly larger than the footprint of the amp, and secure that to the floor with Tec Screws or other self tappers.

Then, use a wood screw to anchor the amp to the plywood.

This is necessary to keep the chassis of the amp isolated from the car's body.

And yes, a seatbelt bolt is fine for a ground point if you clean away the paint.

Vent should not cause any problems, but you can indeed block it off if you want.

 

Ditto the above, although I would use a sub floor adhesive, [Ultragrip 4000 or the like] to mount the amp mounting board, I hate drilling/screwing holes in car floor pans if I don't need to.

I just duct tape up the under seat floor vent, it will just increase the air volume out of the other vent(s). 94

 

Well im glad I asked!

I will lift the carpet up, install the piece of wood(will MDF be ok or is plywood the best to use?) securing it to the floor(ill probably use the subfloor adhesive method) and the using wood scred to secure the amp to the wood.

 

Plywood is better, but MDF will work, just predrill the mounting holes if you use MDF. 94

 

I just used wood screws to mount my amp directly to the carpet, under the passenger seat. Not the best method, but it has stayed in place for 2 years without issue, and I autocross the car.

MDF is usually heavier than plywood, if that matters to you.
