I have never heard of a wall being illegal. I've ran one in the Beretta GT, Chevy Astro, and soon to run one (hopefully) in a Crown Vic or Saturn Vue. And before it's asked. I have also painted the inside of my windows. Been driving like that for a few years now without any problems.

Deadener can raise or lower score. Depends on the install. I've heard of people losing 4dB by using the stuff. Others have gained that and possibly more by using it. I gained 1dB just by doing the very front of the cabin. 96cu.ft of deadener if I remember right.

I use a pair of side cutters. It takes a few tries with it, but works good. For crimping I use a screwdriver and a hammer. Then I drop some solder down inside the crimp just to try and make sure the connection is going to be good. And yea. You have to make sure the wire is placed where nothing can really rub against it. I just found out today that mine is rubbing against part of my steering. This causes me to sometimes not be able to turn the steering wheel all the way to the left. I'm gonna work on that during lunch tomorrow since it's getting to dark to work on things tonight. If you're gonna run a battery bank of any kind try to use either a buss bar or 4/0 between the batteries. Don't go to a lower gauge wire. Kind of help even out things a little (bigger the connection = more juice, of course). Be extremely careful if you put the 4/0 crimp lug on the back of an alternator. I did this once and had to tighten it up about every 4 or 5 days. I even tried doubling the nuts, but that didn't help. I would advise to put it on the battery instead (unless you're going to run a secondary alternator and don't have room for another battery under the hood).

I am using 4/0. Didn't get it from weldingsupply though. When I bought it the cost was $5 a foot. Easy to work with? Not really. It's flexible as hell but it'll still be hard to run in certain places. I've got mine run under the van right next to the frame. All intentions to one day run it through the frame. Expect one hell of a hump if ran under carpet.

3/4 to 1" square tube welded to make a frame for the enclosure. 2 layers, minimum, of 3/4" MDF for the enclosure. 3/4" all thread for even more bracing. It'll take one hell of a lot of welding for the sides, top, and back. It'll take even more to do the baffle. I'm talking framing in around the sub holes and joining those together. (picture a pair of sunglasses. Lens frame are the sub holes, nose piece is the joiner). That will make one hell of a stiff walled enclosure, IF done right.. I have actually thought about buying a welder and doing the Astro this way since the next build will be the last build for the van (going to probably get a crown vic walled)

Test tones provided by shizzzon there ya go

Hey Shizzzon, you got pics of said wall? I might have missed it, but what's it hitting right now? music or burp? I've done 148.2 on music with 4 15s and 4kwrms in an almost complete wall. Yea, I still want that 1.8db and think I'll get it with a little bit of playing and/or finding a better song. Wanna see my almost complete wall? Here it is. Can't remember the ft^3. I think it's around 20 before port and sub displacement. Tuned to 35Hz. Shakes the hell out of everything around it

I know this is a couple month old thread, but.. I'm surprised no one has mentioned this. Even though it looks better to have everything centered. aim the wall slightly toward where the meter usually goes. This may or may not give you a dB or 2. I gained 1.3dB by moving my wall passenger side back a bit. Keeping the drivers side of the wall in the same spot it was.

I probably should start a new topic, but figured I could jump in here with a quick question or two. Will a HDC318 or HDC318-A (Dvc2ohm) handle a SoundStream a SoundStream XXX-6500d at 1ohm on 18volts? What about a xxx-4000d at 1ohm at 18volts? These will probably be the determining factors on me investing in 8 to 10 of them.

Get a HO alternator and 3 batteries (minimum). 1 would replace your current starter, other 2 in the back. I've ran a xxx-4000d on a stock alt and 2 batteries. Voltage dipped lower than I liked when system at full tilt. Changed out to a 250amp alternator and voltage stays at 13.5 when system is at full tilt. Jumps to 14.5 when I bring the idle up a little. Hope that helps

19.2 volts will do just fine on a 16volt system. That is what my alternator was setup for when I had the 16volt setup. Scottie (powermaster) was the one who told me to run it at that.

Quick question. How's the voltage holding up when the system is up? My Powermaster took a dump and thinking about replacing it with a Mechman one (or two) Van looks loud, wish I could hear it in person

what's happening with this build? more pics and info please

I Have dealt with him 2 times without a problem. Had a 180amp in the Beretta and have a 250amp in the Astro. He ships quick and will help you out with any problems you may have. Now..... Reliability is great. Alternator seems to do what it's supposed to. I have to keep my engine idled up to be able to keep my electrical at 14.6 while having the system turned up (4 soundstream splx 154 subs on 1 xxx-4000d amp @1ohm, on 2 batteries.. no where near enough batteries). If I do a normal idle with system up, the voltage goes down to about 13.2. Some have told me that his alternators are not good for huge car audio systems. I bought from him due to having other places money needed to go also. I am pretty happy with it and am pretty sure as soon as I ad more batteries things will be better. Then again.... I keep hearing a small voice in the background saying, "EA, EA, ya should've bought an EA alternator". Hope that helps

Need more pics. Been waiting and waiting it seems like for months. hehe Anxious to see what has been done

Can't wait to see this one. Always interested in Astro builds

Congrats on the new born. I pretty much know how you're feeling right now as mine was born 4-24-08 at 8:25pm.

I've heard different stories with those batteries. Some have said that one side, or the other, would never get fully charged. My team mate is currently testing 2 of them to see if they're all they are cracked up to be. So far they are doing great.

Just to give ya an idea of a 16volt system. This is mine. 1 - Powermaster 350amp alternator with variable regulator. 14 - 8 volt golf cart batteries 4/0 welding cable from alternator to batteries and from batteries to frame Alternator charges at 19.5volts. I had a brief discussion with Scottie Johnson (product manager and R&D for Powermaster, this is a quote from an e-mail from him: My batteries sit at 15.73volts when van is not running and system is not playing. With van runnning, at idle, they jump to 17volts. At 2krpm, the meter jumps to 19.5 volts. I have to keep the rpms at around 2k to keep the voltage up, since the xxx-6500d is a power hog.

If you can afford it, go with the bigger one.

There are certain things that fall within each class that try to even the playing field for everybody in that class. These are things like how many subs, what size, number of batteries, numbers of amplifiers, number of caps (ugh!, I hate that one, caps suck). Bass Race is completely different though. A 1500watt system can go against a 150,000watt system and win. It's all about control of your system (knowing your system). If you look at the rules, for any organization, you can see how they try to even the playing field. Doesn't always work though as you have those that have the need to cheat to accomplish anything.

Well, since we're talking about our first computers...... My mom bought the very first Tandy computer to ever hit the shelves. In the attic of her house we have a Model 1, II, and III, along with a coco and model 1000/sx. My first computer was a Ti-99/4a then I built a timex sinclair zx-80. It was a kit my dad bought for me to play with. Then I got into running a BBS on WWIV using a packard bell 286. Can't remember the exact specs, but it was so slow. Now.. I own 9 computers, half of which are currently running. Speeds range from 366mhz to 3.0ghz. All running linux, one distro or another. Main ones that are used everyday are running PCLinuxOS 2007. the daily used systems are: Mine: Intel 2.8ghz P4 with hyperthreading 1gig DDR ram ATI 9600 256meg vid card close to 1TB of usable drive space (200gig Western Digital, 300gig Western Digitial Rock external USB, 250gig Maxtor, generic 80gig external USb, and a 160gig Maxtor DVD burner 52x CD Burner Hers: AMD Athlon 2400+ 1gig DDR ram 160gig Maxtor DVD Burner Nvidia 128meg AGP vid card. The rest are either firewalls, ftp servers, LAN game servers, and network storage (like I really needed more space) Every computer here is built by me. The 366mhz system is actually a Abit BP6 with dual Celeron 366mhz processors. Believe it or not Damn, I've been into computers for far too long

Always good to see an Astro vid. Maybe one day I'll be able to see it in person. and you forgot about one person when naming some heavy hitters. Step Harris of Pure Pressure Audio (in Gainesville). 24 12s on 4 SS xxx-6500 amplifiers. But you are pretty much up there, from the looks of it, with all the heavy hitters here.

A teammates system. Not sure on box specs. 4 Fi Audio 15" BTL subs fully loaded running on 2 SoundStream XXX-6500 amps. I took this video last weekend and forgot all about it until now. Click here to watch 4-15--Fi-Audio-BTLs I should ask him about the box specs this weekend. Heard he's fixing to change up things a little bit though.
