I am installing a system in my 04 extended cab. It will only consist of factory head unit, Infinity Reference fronts and rears, Phoenix Gold PLD, EQ, 5 Channel amp powering fronts only and 10" Infinity Ref sub. I want it for sound quality, not loud but be able to play the low notes with control and maybe a little feel. I have just found out that by the time I fab a sub box (bottom fibreglass and rest MDF) that it will be lucky to be 1 cube. I don't want to use up the complete area under rear seat, am trying to leave passenger rear under seat empty for jack and kids stuff. EQ to be flush mounted into top middle of box and hoping amp to be behind rear seat. Not even sure if that thing will fit back there yet. Any ideas are apprectated, as well as dimensions and cubes of any boxes for new body style extended cab GM's.

 

I have pics of mine here...you could easily halve it above the tranny tunnel. You can get more than 1 cu ft if you fire the sub forward. Maybe like 1.5 if you go sealed.

Get an JlAudio stealth box and be done with it color matched and sounds awesome. You have kids it's hard to build a box when you have little ones running around.

 

i'm just running a custom fit 12" downfire box. under one side of the back seat. i need the other side for my nitrous bottle.

 

Made my own for one alpine type r 12.

 

here are pics of my box.

 

 

I have an infinity 10" under my rear seat on the drivers side. The box isnt a cube, but its damn close. If you built so the box was under one side of the seat and over the hump you could easily get a cube.

 

holly crap Holty, you did finally get that box done for them w7's, looking bad a$$ bro
