Trunk to small? Full JBL System

Just looking for suggestions on what to do with my trunk. I can't figure out a good layout. My current system isJVC MP3 CD Car Deck (KD-LH300) 2 x JBL 6-1/2" Car Speakers (GTO626)(Front)2 x JBL 6-1/2" Car Speakers (CS206) (Back)What I have to put in my trunk:2 x JBL 260W 2-Channel Amplifier (GTO75.2II)2 x JBL 600W Mono Amplifier (GTO 601.1II)4 x JBL 12" Subwoofer (GTO1202D)At the moment I only have 2 of the subs hooked up and only one of the 600W Amplifiers. I have a 1991 Honda Accord and trying to figure out how to put it all in. Fiberglassing is a option but I want to do as little of it as possible. At the moment I am thinking of having two subs behind the seat facing the back and the other two subs in the back right and left angle facing back. Then maybe trying a false floor and having the amps side by side in a grid. Haven't looked into it yet but powerwise my car going to be ok?Also one question. I have heard about cutting out a piece of your rear deck in your car sort of acting like a port from your trunk to the inside of the car. Anyone able to explain pros/cons of this?

yea my uncle and his friend have it like this, u cut out that piece behind the armrest, and create the box so that the armrest acts as a ported enclosure when it is down, and a semi sealed enclosure when up.  I dont think there are any cons to that install.  My uncles friend had his trunk sealed in the middle with plexiglass and had 2 12" kicker L7s and when that armrest was up, the bass was mellow and loud as love outside, could be heard for blocks.  When it was down damn I swear the hairs on my head and body were partying, they would ****ing move around and $**T lol.  I myself did not notice any cons, except that if u have 3 passengers in the back seat you need it as a sealed enclosure.  It is really cool.  I wish I could do it with my car cuz it is like 2 different boxes in 1!

your going to need a power cap for sure, youll love up your alternator, or just buy a bigger alternator, one of the 2
