Because standard ported boxes are easier to tune for Spl.

thats not a bad idea...i'll think about that.

Most of the space will be provided in the cabin-side of the box

I would very much like an Explorer (favorite car), but i couldn't afford the gas.

Damn. What woofers would be able to rival the output of the BTL's, while cutting down on weight? My goal is low frequency SPL.

looks like i need some balloons!!! Lol. Hmmm. The weight issue didn't occur to me. i know a stiffer suspension will raise capacity a little, but i would think it puts more stress on the car. I am prepared to make additions to my budget, within reason. $6000 for airride is wayyyy too much, out of the question at this point, not for my first system. My whole theory behind this system, is "do it right the first time, never do it again" (within reason) my first idea to lowering the weight is batteries. Are there lighter batteries that could feed the 4500D's? Also, are there lighter woods i could use in the box? Thanks for all the positive feedback, i am really looking forward to this!

Oh, this monster is going in a '99 VW bug

this is a great point. x2 How much does it cost for a suspension upgrade/airride for a 99' Beetle?

Alright. We all know i am always proposing new ideas for my future car. But I think I have my heart set on this. Money isn't really a problem, I am applying at a few local shops, and i have plenty of time to come up with my budget. My rough estimate is around $4000. Here goes: 4 - 12" BTL's 2 - Sundown 4500D's 4 - Powermaster D3100's 1/2 - HO alt's (Brand TBD) 4 - TB 6½" Speakers - Front/Back 2 pairs - Pioneer TS-T15 Tweets - A/B/C Pillars 1 - Sax 100.4 1 - Audiocontrol Epicenter Box: 8^3ft @ 30hz ________________________________________________________________ My biggest concern at this point, even with a proper enclosure, will 4 BTL's be able to breathe? My goal is high 140's to mid 150's. This car will be for shows (not big elaborate competitions, i am talking around-my-town shows.) I want to show Plainfield what Fi and Sundown have to offer. I can't manage to get the design right in paint (I need some time to mess with sketchup) but i'll try to describe it. The 12's will be in a 2x2 configuration, the baffle will slant from the rear deck to the platform (i will most likely be removing the seat, unless folding them down provides enough clearance.) The back part will be flush with the wall between the trunk and cabin. It will then have a rectangular part extending into the trunk, providing the appropriate airspace. Throw me some feedback, I'll sit down later tonight and try designing it on google. -Thanks,

Kewl...

Elaborate?

Damn!

Thanks for the quick repply, Fi subs in the UK are to pricy i want to buy from the US! I will not pay hyped prices we have in the UK , i can buy of your web site for 384usd and in the UK they are 806usd!!!!!!! ATB P.

huh-wuh?

idk what frequency it was, but these damn things couldn't drop low for anything. idk what it was. Thats why you have a sub...

No. A deep cycle battery is good if you intend on using it up, draining the battery before it gets recharged. It is designed to handle the stress better. A "wet" battery is simply a lead-acid battery, one of the most common found in most cars.

The port size is fine. However, i am pretty sure there would be some cancellation issues with mounthing the woofer that way.

Evil power/ground wire?

Technically it woulnt be a fiberglass box, glassing is just done for cosmetics and where every bit of space is needed. The large part of it, if not all of it would be MDF

Thanks for the info i will read up on it a little more, and see whether its worth trying it on my current battery.

Think a quick Google search could find me the right ratio... and how would i measure it?
