Just finished off my amp installation behind the driver's seat.
I positioned a piece of plywood between the firewall and the carpet, and the mounting screws go through the carpet and into the plywood to make the whole thing nice and sturdy.





The last thing I have to do with the stereo is to make my sub enclosure. I have all the materials, so I just need to find the time to do it.

Nice. Is the plywood secured or is it just held in by the carpet?

I was going to stick the plywood to the firewall somehow, but I decided that it was too tricky and not necessary. The plywood allows hardly any movement of the carpet, and the carpet is quite stiff anyway, so there's no way the carpet could ever fall out of place. It also allows the amp to move a few mm which should absorb vibrations on bumpy roads.

I put a bit of padding in between

Did you get this idea from me :)

With my audio background just share a few tips.
On MDF i have NEVER used screws to attach anything.
Use timber TTE NUTS that way you can use a small bolt to attach the amps.
This way you can remove any time , how many times and never thread the timber.
Also secure the MDF to the body by using SIKAFLEX 255 Top stuff.
Now if you mounted it under the seat you could use very thin MDF 6 mm glue it under the carpet with the TEE NUTS on the corners. Then add a couple of washers and have the amp suspended off the carpet.
Also tiny slit and have all the wires hidden.

Just a thought. Out of sight out of mind

Tee Nuts you can get at the bolt bloke or even Bunnings. Just make sure
a) Italian ones they are great , buy satin ones , if they a polished shiny stay away from them ,the spikes break easily. Then if your going to use 3/16 inch i recommend retaping the thread actually retap any one you get , you'll thank me latter :) Bed the TEE NUT into the timber by puting another spare piece of MDF with a drilled hole then a bolt with a big washer. DONT use the amp to bed the TEE NUT.
Second drill the hole in the MDF of your baffel with the shank size of the TEE NUT.Again you'll thank me latter :)
Use only thin MDF that way it wont raise the carpet too much then all you have to do is little holes in the carpet for the bolts.
The sikaflex is very strong. Thats why use thin MDF as the MDF will rip off the Sikaflex if you want to remove it latter but the Sikaflex will have to be cut off

I'm trying to decide how my sub enclosure will be fixed in position behind the passenger seat. I'm definitely putting it on top of the raised box behind the seat, and I'll definitely be building it out of MDF with black carpet wrapped around it, but I'm wondering how others have attached their enclosures behind the seat?

I've got a 10 inch pioneer slimline sub in an enclosure built to fit behind the passanger seat. I just used those adhesive velcro strips on the bottom and rear of the enclosure. Don't think the sub has moved an inch and it's been in there going on 2 years
