I am eager to see the results of your "redo". Any pics of the new wall installed?

A couple of this year's fawns. I shot this pictures in my back yard

Make sure you check my numbers!!!!!!

Here are some graphs. Plotted are 2.75 cubes and 5 cubes both tuned to 45hz. 5 cubes has a higher peak at tuning. Xmax is controlled at tuning on 5k. If you play anything lower than 40hz on 5K you more than likely will mechanically damage the driver. As far as port area goes..... Since this is a burp box (it WILL sound like complete shit on music), I would go as big as possible. (2) 10" aero ports will need to be 35.5" long each or (1) 10" aero will need to be 14.6" long.

Shit just got nuts!

Model this in WinISD Sencheezy. 2.75 cunbes @ 45hz 4 cubes @ 45hz 5 cubes @ 45hz There is almost a 3db gain from 2.75 cubes to 5 cubes. Tuned at 45 hz, no matter what size enclsoure you SSF should be set no lower than 38hz@24db for 5kw (you didnt stae power but a couple dudes on here are running 5kw for burps). The ZCON is very peaky at tuning, no matter what he freq is or enlcosure size for that matter. Definitley a boom box driver, needs a large enclosure to get the most out of it.

First off 2.75 cubes for a ZCON is a little more than half of what that driver needs. Big volume and lots of power gets the ZCON loud. Easiest for corners are 45's. Flared ends internally and externally are a must with round ports. What freq does your Explorer peak at?

I think the material used is not as important as the enclosure design and build construction. Try to eliminate rough surfaces and use smooth rounded transitions in corner joints. Port entry inside the enclosure and port exit outside the enclosure should be designed for efficient airflow velocity for your enclosure design. That doesnt mean the biggest port possible. Bracing needs to be effectively used to not prohibit airflow to the port yet to eliminate enclosure flexing. Eventually weight will be an issue. Your vehicle has it's limitations. If you can find a void free birch plywood that is my choice. I know in my area all there is is C grade China crap

Thanks guys! I can see how these SPL comps can be addictive!

Sundown I assume. I am anxious to see what subs you are running. Are you waiting for the new NS to be released?

New car smell is overrated lol Enclsoure looks like a pro audio sub.

But who drives with their head in between their legs, or up in the windshield? Or in a globe lol

I demoed it a few times before the run and everybody thought I was close to 150. I think the "wow" factor of the 18" makes it deceptive. IASCA was there too. Maybe I should have went over there Doesnt matter much. I didnt design this system for SPL.

Just for fun I took my car to a local MECA event. The judges and organizers were extremely friendly and very helpful. Excellent group. I was placed in M4. I have a DD M3a and a single 18" Z.3. My enclosure is the complete opposite of an SPL enclosure. I can only imagine what it would do in the right enclosure. I managed a 142.87 @ 35hz. Not too bad I guess. I really thought I would be over 145 though.

Comps are a lot of fun, I am hooked! I am going to try a talk my wife into letting me use her car as a burp car

I enede up switching out my RS225's for Jl Audio ZR-800's. The midbass is very similair to the RS225's. I need to mofidy my enclosures to run these drivers IB. Went to my first MECA comp today just for shits and gigles. I pulled a 142.87 @35hz. My enclosure is no where near built for SPL so this score isnt too bad. Not as high as I thought it would be though. I am really anxious to get the dual 15" Z.3 in and the VFL-450.1

Sweet. Anxious to hear your thoughts on it

Aeros?

I see someone bought an amp from car audio classifieds

There are many active crossover options. I prefer active head units. Pioneer, among others, offer active h/u. I have a DEX-P99RS. The JBL MS8 is a popular processor and not seen often in the car audio the MiniDSP (very nice, highly expandable option). ....among many more.

After reading through this thread I am not sure that you know the differences between active and passive crossovers. This may help explain. http://firenzeaudio.50webs.com/tech_xover.htm Have you heard any newer component sets installed in factory locations? It is possible that you are looking for more than you need right now. Imaging and stage height will more than likely be compromised compared to am elaborate a-pillar install but maybe it will be good enough for you or atleast a good start.

Dang those amps are huge. 18+ & 18- WOW!!! Might be cheaper to run solid copper bus bars lol

I have an American Bass VFL-450.1 I will be swapping out my DD M3a soon. From my experience so far the customer service is great, shipping was fast and the amp is beastly I have not heard of issues with American Bass amps. They are known for making rated power.

An American Bass HD1500 would work well for them.
