I've got 2 13w7's going in the back of my is300. The problem is that I have no trunk...but worse is the fact that the back seat and rear deck are solid... All I have is a 8"x10" "ski port" and 2 6"x9" speakers in the rear deck. I'm concerned that my sound won't make it in the cab (as good as it should). Any suggestions, I hope I'm wrong. Fire away!

I've always had a blow thru in my mini or a hatch. So now I'm thinking if I point to the back I'll have hella rattles, or if I face to the front I can't show off the subs.....unless I use Lexan or Plexi for the rear of the box.... but the slot port will cover some of it. Delima's Also, I can't find any builds with the is300 on the net, CRAZY. There's a build for a tricycle and a Yugo, but not my car... Anyways, I'm also thinking of pulling the 6x9's (either way) and porting up, except that would be a pain to line up and figure port on, not to mention the potential for port noise. I can't wait to drop these two in this car! I've got a 1000/1 for each, should be quite loud (even for JL - for all the JL bashers) BTW I'm no JL fanboy, just a guy who got a "deal".

I dont know how in depth you wanna get with the install but heres an idea from a previous build.

most on here will give you the advice to get rid of your 6x9's and just go with a component set up front. I did in my car and unless i tell people they dont realize I dont have rear speakers.....

there are plenty of options

1) start cutting

2)build a regular box and always leave the port hole open

3) option 2+ remove rear speakers for more air flow, and get a nice strong front stage setup

4) port the box through the ski hole (i've never personally done this though, so you may want to ask more about this)

do not cut up an IS300. please, remove the rear speakers. it will sound and be just fine.

I've got a strong front stage, and I do plan on pulling the rear 6x9's. Although I do have a set of 6 1/2's I was thinking of finding a place for in the rear. I think the holes in the rear deack will help though... Now onto box design...

Here's a thread that contains pic's of how the bracing is on the backside of the seat and the rear deck. This is why I have the question on how to best get the bass/air movement to the front cab area. That's the tightest bracing I've ever seen!
