I think i will use the memphis stuff since i have it already and it does sound pretty good.with the diamond audio stuff it should be what i need im thinking..thank you for your help

Two 12's would be awesome, I would put both in turn the gains down if you don't like it. I like my two 10's which I was advised against, glad I went with two 10's not one 12" can't beat the punch two give you.

As mentioned, i would do 1 -12, since you already have it, but 2-10's is what i'll be switching to. As for fronts, yet the 6.5" will fit, Also your amps should fit, under the hatch floor in front of the spare tire, once all the other stuff (if you have any) is removed.

do i create cutouts so the amps can get enough air to cool? im not really sure the spot u mean but il look

I highly doubt that those large amps are going to fit under the floor. Maybe if you remove the spare and build a amp rack that is the only way I see them fitting under there.

Check out my install pics, as to where i mean, and the amps i put there are big, both are 9-5/8 x 16-11/16 x 2-1/2. Thoughs Memphis amps are way narrower...

Whats the sound difference as to a up firing sub compared to a rear firing one?

Rear the sound has time to space out and become louder as it bounces off the rear and GOES FORWARD. As aposed to going up and than down.

Hey how do you like the sound of your sub, i just noticed its facing up..also do your amps stay cool enough covered and hidden like that? Awesome install by the way

Thanks, yeah the amps run fine, i resently did a 18.5 hour drive to Vegas stereo waaay passed half and no problems. The sub in a hatch wont have any real sound change like it would in a trunk. i'd say face it what ever makes sense for the install you want to do. I like the sound of it, but i'm used to more bass, so i'm going to change out the single 12 for 2 of the 10's, same series though. I have a single 10 version in my truck and it hammers!

In a small hatch the sound waves don't have the room to do anything, it wont matter faceing up or down, back or front. or are you talking about controling the movement? cause if you have enough power it will be tight and very controled no matter which way you face the sub.

ok thanks for the info
