Hello all this is my first post and I am new to this whole forum thing. I just bought a 09 ram crewcab and want to put a pair of 12's under the back seat but not sure where I should get them from or if I should just have someone build them. Any information that I can get would be appreciated i.e. specs websites pics, or instructions. Thanks

 

If you want a prebuilt box, anything built for a quad cab from 03 up will work... MTX has them...

 

I was just making sure because I found a 08 crew cab box but it seemed like it didnt fit in their perfectly. Just was not completly sure if I should get that one or spend a couple extra bucks to get an 09 box. By the way has anyone purchased anything from brighstarcaraudio.com

 

just my 2 cents, but if you want to use 2 12's I would do a seat lift and build a fiberglass box the uses all airspace available.I did that in my 4th gen and sounds great

 

I was thinking that also.....someone also told me that rather than risk the 12's with the limited space I should get two 10's (cvt). Also should I dynamat the doors and rear?

 

Dynamat will make the stereo sound better and help with the rattle. Not to mention kill some road noise

 

Do you know how much dynamat would be needed

 

No I dont but you can use some stuff called fat mat. You can find it on e bay. Just a guess, 50sf should do the roof, doors, back wall and part of the floor.

 

Here is a pic of my first experience using fiberglass and resin. I used the carpet as a mold and then used 3/4 inch mdf to finish the top of the box. I also have a 1 1/4 seat lift. the seat lift is made from square tubing I bought from home depot.

 

So my foxbox from my 07 will work in my new 09?
