cool thanks for the tip on the metal bracket. might have to look into that for my new box build.

For the Aux and USB input i used a step-bit, or uni-bit, whatever you want to call it to drill the whole and with the usb i used a small drill bit and then filed the rest of the plastic away with a small file. Securing was pretty easy, there are plugs behind that piece which allow it to be centered easily then i just filled the plugs with hotglue, a ******on of hotglue, and that was it.

There is a curved metal plate under the seat for support...you will feel it about 6" or 7" from the front of your seat...someone on here has pics of how to cut it out for more room under your seat. And what did you use to cut out holes for the usb and mp3 input by the cig lighter? That looks real nice!

hey man, the metal plate under the seat, not sure exactly what bracket your talking about, but i can tell you that all i did was remove the jack and whatever into my toolbox, i did NOT remove any brackets or install a seat lift or anything. The box sticks out a little further than in that picture you commented on, but not much at all, barely comes passed the front of the seat. As far as the dimensions on the box, its a cheap box that i bought from supercrewsound.com, not too happy with it but it works and sounds alright. Im trying to find the time between class and work to fiberglass an enclosure to better match the subs.

They will fit though, the JL10w3v3's can fit under the seat. all i did to the supercrewsound box was cut a square in the top and nailed a piece of mdf over it so the magnet would fit... Seats still latch down, you just have to push on them a little, but not hard or anything. If you have any other questions though man just ask, im always willing to help someone out.
