Some video

Thanks for clarifying on the carpentry end. Like I said, I was given bad information there and I'll correct that in future. The question here isn't what I know or don't know it's about the other person throwing an off handed jab at me regarding something about which he knows nothing. I in fact did some research and testing before I chose materials and methods, and as I said, the only people who are talking out their arse about using OSB are those who never tested it and never spoke to anyone who tested it. Quick to make ignorant comments and quick to run off when challenged on where they got their information.

Cool, I guess I was given incorrect specifics from the guy who recommended it to me. It doesn't change the fact that your buddy shitposted up my thread with his ignorant comment. Now do you have any useful experience or objective data regarding building walls, OSB, Particle board, or epoxy or are you just shitposting as well?

Anything that could be integrated via bluetooth with iPhone/iPad/iPod or android device would be a good selling point. People love using their portable devices... though I don't know how practical that would be.

Like more of the build log or more as it sits now? V1 and V2 come up for 500$ish on eBay here and there. Like I said, if you're not trying to drive 2 amps into 1 coil there's no need to strap with the non-invert output to a second, third, fourth, or 8th amp. In other news, after smoothing out the port some I metered 152.4 today. May or may not have more... I stopped rolling up the level when I got scared not because the meter stopped going up. I'm considering pulling the front seats out just to show a better number at the next competition up here as well... all my numbers so far are with the seats in and no special attention paid to position of interior pieces that may or may not alter metered output by a tenth or two. Sadly the build to beat in my area in my class is the blue T3 van so chasing 10ths really doesn't have much appeal to me.

I have no idea. For burps or high record levels the level on Ra never goes above halfway, though I need most of the dial to get max output from some older recordings. Gains on Minotaur is set about halfway mark for what that's worth. Frankly I don't put much stock into nitpicking that sort of thing. My motto is "if it sounds good it is good", and of course when I meter I just watch the meter and roll up the level on Ra until I'm happy... though I think this has a little more in it than I got my last time out. I'm trying to not break anything too quickly since I know Stephen will give me the "Son, I'm disappointed in you" lecture for running them at 2 ohms and fusing at 60A. That's OSB (Advantech flooring). Ooooooh, flexy. Have you actually done any testing with it? How many layers? How much eopxy or polyester resin did you use between layers? On the surfaces? When you built the identical box with whatever material you think is better what were the SPL numbers on each box? If you haven't used that material or done direct A to B comparison or at least talked to someone who has you should probably STFU when it comes to things about which you know nothing. Also this thread isn't to start a pissing contest aboutf lumber, but to show off my Zed amp build in the Zed sub-forum. Wow, that hit a nerve. lmao Notice he hasn't replied with any actual experience or objective data? I posted on SMD forum and it turned into 2 pages of shitstorm of people who are simply trying to justify the 100$ a sheet they paid for "Baltic" plywood or whatever. The guy who insisted that MDF was the end all-be all of enclosure material even has a youtube video comparing different materials.... which consisted of measuring thickness of the sheet and then weighing samples of them. Which is the same as implying that lead is stronger than Scandium/aluminum alloy because it's more dense. So yeah, bullshit, myths, and hearsay is a hot button for me. It's funny how all the forum know-it-alls run and hide when you ask them for proof or if they have any actual experience, yet the guys I know who have actually tested with particle board and OSB + resin have actual objective data and proven results. And this sort of thing extends way beyond just this topic.

That's OSB (Advantech flooring). The only 3/4" sheet that's OSHA approved for 24" studs as flooring. I laminated layers together with some thickened epoxy and painted everything with epoxy. The plan was to do the same with particle board, but local lumber yard had none.

Did some initial testing with the Crown amp. Unfortunatley I changed the port at the same time I switched to Minotaurs so I have no idea what direct swap gain would have been. Though I dropped tuning 4hz, sacrificed 42 square inches of port and am still up about .4dB. Geometry of the cargo area didn't allow my 5th battery on the Crown and voltage drop was severe. Minotaurs seem to run quite happily on this battery bank and have an audible improvement in sound.... I expect 8 amps vs. 1 has an edge in damping factor. One thing I really like is the ability to non-invert slave all the amps frorm one pre-amp so I can run 1 amp per coil without the trouble of trying to gain match every amp or having to dick around with strapping. Don't mind the dust on everything in the more recent pictures, I just did some work to the port and did a bunch of sanding. Baffle will be finished with something other than the black paint as soon as I think of something clever and have some time. Metered 151.9 a couple weeks ago before I smoothed out the port and played plenty of music really loud. Amps stay cool and are easy on the electrical. I have all my amps on 60A fuses and have yet to open one. I expect to get 152.0 with the port tightened up, and I expect I can find some more gains if I get ambitious. Also in here is Ra V2 feeding these amps and Leviathan under the back seat running my fronts. Also back seats fold up as normal for when I need the passanger space.

My SPL-Labs is as good as or better than the termlab I used to own. Definitely more user friendly IMO (thouhg I have wireless version and use Android app). I wouldn't waste my time and money on a TL again. If you got a bum unit, send it back and if you can, upgrade to the wireless one. I think you'll like it. Still not loud Sorry to hear that. Let me know if you want me to help you out with that.

No he is not making assumptions, Steve himself stated those amps only put out 45 watts. The man who built them spoke on the issue on multiple forums as well. This ^^^^ . I have used a bunch of these old Boss branded Zed amps in my own and in friend's cars. Stephen was very honest about actual output and I think was rather perturbed about Boss insisting on over-rating everything. ALL his amps prior to that had always been conservatively rated.

I really should change the name of this topic, as it is not really a group buy so much as it is more of a last chance on some quality 4 channels that are no longer made anymore, for a nutty price. These amps are already shipping, they are going out as the orders are coming in. We spoke with ZED last night and a bunch more shipped out yesterday. The quantity is getting low, so I would not wait too much longer. There are a couple of another model left that is similar to this model, but we won't put those up until all of the REV-665's are gone. We have a people buying these a fail safes, back up amps, quality amp for their girlfriend/wife's car, first amp for their kid, ZED collectors, or even some people who have bought them to use them as 2 channel amps for more power to their mids or mid-bass for a great price. I realize you may not want to spill the beans on the other amps just yet, but will there be any larger amps? I like savings the money. I bought the last of his BIG 4 channels about 4 years ago. I suspect he has some smaller ones and some 2 channels (also smaller). Of all of the old Boss amps, these are about the best. The larger one had an impractically large footprint IMO and wasn't nearly as pretty as these. If you could rub off the BOSS and rediculous power rating from the plexi on this it's a gorgeous amp.

I have used OLDER Stetsom 7Kd and 4K2D and really liked both. Made rated power, tiny footprint, and both would play music for hours without issue. That being said I have no experience with the small ones, and I have heard the big ones are real time bombs.

The BOSS branded Zed amps are grossly OVER RATED. These are rated 200X4 or something silly, they do around 45-50W per channel into 4 ohm. They are very nice looking (and sounding) amps. Small enough to get under a front seat in most import cars (did one in smaller Toyota and Hyundai). I have a few of these stashed here "just in case". I picked one of them up this winter as a souveneir when I went to visit Stephen at the shop. These were made in the days when he had 100 employees and were building 1000 of these a day. He told me he NEVER had one of these come back blown. They seem rock solid. @Aaron Take the damn plastic wrap off the top of that!
