Screw the trunk, go all out HondaEtr style.
Just find out what kind of volume the subs require, and work with that. Its best to have a bit of a bigger box then what would fit: AND have great sound... then only go for a VERY small box, and have to deal with very shallow and poor sounding bass, as the box is too small for the subs. Thankfully Kicker subs typically require small boxes, so go with a small sealed. I'd recommend about .7 ft3, which is (I'm pretty sure) along the lines of what Kicker recommends, as for a sealed, they recommend .5 to 1.0 on the sealed boxes for their 10's. Just dont forget to find out the NET internal box volume, exluding the thickness of the wood, and the volume loss from the subwoofer itself.
Yeah poly fill works wonders. I have 12's in mine and I didnt want some huge box taking up my trunk So I got a really nice, small, sealed dual chambered box , fillled about half way with poly fill, screwed on my CVR's and voila. Boom she goes. And you dont necessarily have to buy poly fill from an audio store. I was in a fix so I bought poly fill for less than $5 from the arts and crafts section of Wal-mart. Its really just the stuff they use to fill pillows. But good luck man hope everyones info helps!:tup:If you do accidentally end up with too small of a volume of box, you can always use poly fill to simulate a bigger box.
I put the amp ( as well as other signal processing equipment) on a rack that hangs underneath the rear shelf itself, suspended upside down for easy acess. I also installed 12volt fans (from a computer) on a seperate rack made of 1/2" aluminum bars that cool the equipment, as hanging upside down in a closed air enviroment isn't too good for 2500 watt RMS amps too cool themselves.
It worked great though, Just crawl upside down (facing the rear shelf) in the trunk and everything is there. [fizzle]ing PITA to install though... URRGHH!!! Wont do that again.
too bad our trunks leakshallow mount woofers have gotten a lot better since they came out. An enclosure in the spare tire well with a grate over it can sound amazing. Plus, it evens out some of the weight of the car and it's east to slap loads of dynamat in the spare tire well to prevent vibrations. Keep a car of fix a flat in the back seat and a AAA card in the glove compartment. With the right amp and box, one of those will be enough, and in some cases more than two in a different set up. You cal even sell one for the extra cash to put up for a quality enclosure
Actually mine is now watertight, PM me for detailstoo bad our trunks leak
I had the wires running to a home style stereo output jack on other other "cubby hole" of the trunk, and ran the wires from that jack to the speaker box. Great for swapping out subs, as I did that all the time.
