I want to put the amp for my speakers under the driver seat. The problem is can I just drill through the carpet and through the floor of the car or do I need something inbetween. Then the problem becomes how do I secure the thing that's securing the amp.

Thx

I am not 100% sure on if there is anything run under the driver's seat, but go under the car and check there 1st to see if anything might get in the way. If not, cut slits in the carpet, then drill under the carpet there. Don't cut sections of carpet out so it looks cleaner and also if you take it out it wont look bad at all.

One last recommendation: since I have never done this, I am assuming you will want to use a silicon sealer in each of the holes. So drill them, get the screw in, remove the screw, fill hole with silicon, then put the amp on.

if you do drill through the floor board and silicone.

I suggest using pop rivet nuts.

Good idea!
But still seal it!!!

no worries about the carpet, just use a self tapping screw and go to work.

the screw will pop through the carpet, and through the sheet metal. there are no "things" under there, but there are some wires run to the seat, so make sure there are no wires in the way. easy enough to push your fingers through the existing slit and feel for anything.

you can put silicone around the screws if you want, and they WILL poke through your floorpan. its not a neccessity. (disclaimer: I live in california, so rust isnt a problem I have any experience with.)

something to watch out for: carpet is uneven, so if your mounting feet are plastic, dont overtorque the screws or else the plastic will break. if they are metal mounting tabs, screw it. you cant break that!

last thing, make sure your RCA cables and wiring is neatened up. I hate to imagine some rear passenger kicking at my wiring by mistake and screwing stuff up! best to protect yourself from such worries

Pull the carpet up on the side you wanna install your amp on. Get a 3/4 inch plywood slab that measures just wide enough to fill in the space between the seat brackets. Use silicone sealant or the epoxy used in fiberglass around the board to secure it to the floorpan. Then put the carpet back over the plywood and mount your amp on top of the carpet into the wood ensuring you don't use screws that are long enough to go into the metal of the car. This way when you get rid of the vehicle you can remove the wood and you will never have a problem with water getting inside the car, or having to seal the hole you drilled to prevent rusting.

My recommendation would be to get a small board (1/4" think should suffice, 1/2" even better), put some t-nuts on what will be the bottom of the board (to hold the bolts in place), put some short bolts through the t-nuts (just need to be long enough for a nut to thread on at the other end), put the board under your carpet, cut slits in the carpet for bolts to fit through, place amp on board, put nuts on bolts.

Not as secure as screwing right in to the vehicle, but having the bolts through the carpet should keep it pretty secure. And you won't have to screw into the vehicle

Think RUST!!

If you do decide to mount under there and it's kind of rainy/damp where you live can I recommend going under the car and spraying the tips of the screws with rubberized undercoating. Rust be gone...

I don't like underseat applications if they aren't absoloutely necessary. Make sure you have adequate space around the amp for cooling, as you don't want your amp going thermal on you if it can't cool properly. Mount it where th cooling apparatus (fans, fins, etc) are facing the most open space if possible. This will provide the most effective cooling of the amp. I like mounting a board in the car under the carpet replacing carpet and then screwing the amp to the board, as this will provide you with a uniform mounting surface, but could possibly provide some clearance problems. And I like the use of tee nuts in this type of application. Also, make sure you don't screw through the wires under there, or pinch them slightly in the process. The wood could protect them to some level. Another thing to consider is do you have a lot of erar seat passengers? If so, make sure to protect your wires/connections by mounting them away from the feet area.
