actually i have the enclosure, sub and amp for sale, all almost brand new, less than a week of use. my engine is gone and i need to fix it,
the enclosure replaces the spare tire and uses the same screw that the spare uses to keep it down. i made it angled towards the frotn so you can really feel the bass and i can, my pants shake only at 1/4 way, it feels if someone is knocking on your head if i turn it half way, i dont want to turn it all the way becuae i really dont know what will happen, glass broken? battery exploding? lol.
but anyway, I love kicker becuase it really kicks, even the round ones are awesome as i built the enclosure for 12" round one. i was expecting to sell it so i didnt want to limit the options of subs to only kicker squares.
anyway, if you did fiber glass work before its really easy, you have alot of space to work with, the spare tire space is huge, and i even used more than that to make the bass tight and not shaky like 99% of systems are, especially the normal boxes like from best buy or ebay or that stuff. I built mine as a sealed box, its way nicer in my opinion. if you live in jax or would like to check it out i would love to let you hear it, it will make you start cursing only in 1/4 of the power, trust me, i have a friend who never spoke a bad word in her life (supposably) i just let her sit in my car, and the ohh sh** factor took over. she went insane after it, she kept begging me to build her something similar, lol.
anyway, last words, make it a sealed box, use as much of space as you can, the more air the tighter the bass if the sub is good. make it angled towards the front for two reasons, 1- you will feel it wayyyy more than if its flat in trunk, 2- non of that shaking under the car or wipers or any of that stuff, it will just shake the pedals under your feet, shake the seat and bang you on your head, lol.
finally, choose a good sub, i went with kicker CVR, the new 2005 model, its really nice and not as $$$ as JL which is the only other i like, and it looks much nicer (or ricer, lol) than JL black look.
i went with dual 4 ohm coils becuase i wired it down to a 1 ohm and 300 watts JBL amp is really enough, and thats not even half way. and best part is, it doesnt drain the battery, i am running A/C, 2 amps, 8 speakers and the Sub, headlights, electronics,...etc and no dimming, and dont need a cap or anything. if you want to go the extra step get a deep cycle battery like optima.
ahh, i always write too much. good luck with your project and let me know if you need any help.
