hello, up tilll now i’ve been happy with my very basic setup but recently bought a second rockford fosgate amp and am now rethinking my mounting options. I currently have my single amp and my capacitor mounted to my sub box but am now looking at different options. I have never mounted a amp to the back of my seats cause it seems like it would stab a passanger. How did you guys mount your amps on your seats? I’d also like info on mounting the amps to the plastic surounding the trunk area. Pictures and suggestions will be greatly appreciated. Please also see my other thread on multi-amp hook up (I need help with that too 
)
I had my amps mounted to the back of my seats and there was no problem with the screws polking the back seat passangers, but I did notice that I would get shocked when I opened my doors( I dont realy know if that was conected)
I dont know if using the plastic trunk liner to mount your amps would be the best idea, it might not be strong enough to suport it.
I would make a false floor out of some 1/4 inch wood. Its not as hard as you might think, take the carpet out of the trunk and use it as a templat(sp) then go from there.
I am building a custom sub box and amp rack in my car and so far its going pretty smooth. I am using 1/4 inch peg board, because its light, and will hopefully let some air in for ventalation.
Ill post some pics when I take some.
i have a small amp mounted on the back seat with short thick screws… doesnt seem to stab anyone… i threw and pressed myself against it as hard as i could and didnt feel anything…
it works for me but then again its a small amp…
check the pictures in this thread to see how i mounted my two amps along with the cap in my old car.
Do you want to show this amp off or do you want it hidden?? If it’s a small amp and you want it hidden, put it under the front seat or right behind the center console on the floor pan.
If you want to show it off in the trunk, either design an amp rack by creating a false floor or if you don’t want that option, you could mount it into the side panelling or rear of the seat. I have had amps in all of the above locations and my two favorite solutions are making a false floor and mounting it in the side panelling.
Here’s the trick… Get a junked piece of panelling or recreate your’s using fiberglass (cover the panel in tin foil or tape and then cover it with resin… then use fiberglass cloth/mat and resin). It’s easier to get a junked panel…
Mount the amp to a piece of plywood or mdf and trim the sides of the piece of wood with 2x2s or some moldiing (you can use nailing strips too – 1x1 and cheap as all hell). Butt the wood up tight against the amp so as to ‘frame’ it perfectly on all 4 sides. Nail these pieces to the board temporarily and then cut a scrap piece of wood with either a router or jigsaw (you will have a piece of wood exactly the size of the amp (this will be used for the size of the hole to be cut in the panel afterwards).
Anyway… Cut another piece of wood 2" longer and wider than the one just cut (allows for connections and some air circulation). Create a frame around your new board (a nicer one this time though as it will be visible from the outside of the panel).
Now you have your amp mounted to a framed board… Take your piece of panelling (form the car) and cut out around that template we made earlier (make sure you decide exactly where you want the amp to be and ensure that there’s appropriate room behind it BEFORE YOU CUT).
Trace the inside of the cutout onto the car’s sheet sheet metal or board if you used one behind the panel to avoid drilling,etc.). Another good way to do this is to cover the OEM panel in plastic or something and give it a quick thin shot of black spray paint (this will show exactly where the framed enclosure needs to be mounted to be ‘visible’ through the panel. Either way, you’ll figure out what works best for you.
You will want to gague the depth of your trim pieces depending on how far the panel will stick out when covering your work. This is to ensure that the plexi window covering the amp will be flush with the surface of the panel (if it matters to you).
Well then… your amp is on the board… the board is on the car and it’s trimed with some wood in the exact proper location according to where the cut in the panel is. Take a 1/8"or 1/4" sheet of lexan or plexiglass (or any other cheap arse acrylic/polycarbonate) and glue it to the top of your trim pieces (screw it in if you want but be carefull to drill through masking tape or drill in reverse first to avoid cracking the plexi). Now you will have your amp in an enclosure covered with plexi and mounted to the car. Take your OEM panel and remount it in the stock location as usual. You may want to sand the edges of the cut in the plastic panel or polish the plexi, etc. If all goes well, your amp is now mounted in a custom enclosure in the side of the trunk!
Before everyone says to get fans in there… You may want to drill some holes in the trim pieces to allow airflow. If you have a really high current amp or your gains are jacked through the roof, you may want to connect a fan to a relay on your remote turn on for this amp. Because of the design of the side vents in our cars, a few holes in the trim pieces should be enough… the car’s rear vents should take care of any heat quite nicely. If this is an amp you need to constantly tune, you may not want to mount it this way as it will be inaccessible. This method works great for a crossover that has been perfectly tuned and you never want it touched ever again… lol…
Or you could just slap it to the seatback… or cut out the seatback’s metal frame and build a similar set up as above (this way it won’t stick out and will be built-in).

Do you have any pics NEEX? Even links that show a set-up simmilar to what you are describing would be helpful.
