F3RR3T

sweet as model! i was thinking of a box like that but angled in the back ( like the prefab boxes are) to make room for the 18" sub.

do 2 15's if you can. more cone area therfore louder (in most cases)

Just a question but, Why an 18" ?

i like the super low note an 18" can produce. and the "wow' factor you get when someone see's what just made thier drink come out there nose...lol

So what you think of this.

Did 141 DB sealed on the dash (mic was a audiocontrol about 138 DB on the termlab.

Guess your goin for SPL only & no SQ huh?

I have (1) 10 in a custom stealth with a Zapco 350i running it w/each channel to a voicecoil & it's loud as hell. Granted it doesn't shake my car like a SPL machine but it has a very nice tone & is plenty if your gonna be stayin in the car while it's on.

I used to do SPL & had my first car set-up with a single 15" Digital Design DVC sub on a 2200w amp then switch to a Kicker ZR1000(old school, LOL). It did 147 off the windshield & would play 19hrtz like no bodies business. Scott Shope built my set-up. He used to own the famous at the time knuckle dragger that was filled with 15" Vega Strokers.

that setup in my truck was a SQ setup. The system going in my camaro will be a bass race machine. but SQ for daily listening (15's can be turned off and the 8's in the sails can be turned on)

ahh, hidden 8's. I just used a great mid/high set with it's own amp to replace my stock speakers & then thru the single 10 in the back. I didn't think it would be enough but it has proven me wrong, LOL. I daily drive it so I didn't want to get too extreme. Plus I like to go to the track without having to remove a 200lb box first too. It's nice to bump all the way to the burnout box, LOL.

You'll probably get no more than a little over 3-3.5 cu.ft. , which isn't much space for a 18" sub. Have you thought about a rear seat enclosure?
That would give you a lot more room for a good sizes enclosure!
