i'm currently running clarion 6x9's in the front doors, nothing in the back doors, 3 - 10" clarion subs in a common sealed custom built enclosure being powered by a power series rockford fosgate 1500 bdmono amplifier running at 2.5 ohms

 

Xplod head unit with Xplod 6X9s. I like my music with little or no bass, and incredibly loud, so this works pretty good for my deaf-in-one-ear ***

 

I am running one 12 inch mach5 audio subwoofer with 700 watts 350 rms power from a alpine v series amp going to it, i also made my own fiberglass box, you can see pics of my system at http://www.cardomain.com/ride/2538209, i also have 6 inch subwoofers mach 5 audio in my door with alpine tweeters, running off of my alpine v 12 amp going to my alpine crossovers.

 

Head Unit- Pioneer 6900, hooked an external hard drive up to it in the glove box, 2,500 songs whenever you want
6x9 kickers in the front doors
5 1/4 kickers in the rear pillars
duel 10" kicker comp subs
kicker 4 channel amp for speakers
kicker 2 channel amp for subs

 

Box is looking good YJ. Ar you glassing the bottom of the box to seal it? Or are you building the bottom out MDF? Be sure to post some more pictures as you get closer to finishing it.

 

my head unit
speakers in front doors
speakers in back pannel
speakers wired to 4 ohm
crutchfield.com said the speakers wouldnt fit in the front doors but i didnt have to mod it at all and it was a perfect fit the first time

for my bass hopefully (well im 15 since dec 3 and i work at 7.40/hr so i dont have a huge income lol) soon in the next month i will be gettin these in a costom enclosre made by me.
amp (i want to make sure i have enough power for the subs im getting and any future subs i may get.)
subs (two of theese beasts.) (only goin with 8" because idk if i can get anything bigger than them in here)

ill try to get some pics of this stuff next time i get around to takin pics of my truck, maybe after it gets a lil warmer here in iowa.
but everything i have so far speakers and head unit is hooked up and works 100% and i love it so far no complanits but i do want a little bass for showin off lol.

 

The whole box will be MDF. the bottom is whats gonna take me some time as i'm gonna have to cut multiple panels to make up the bottom.
