So heres my idea. I was looking at the plate the guy made just recently and he has his amp on the bottom of the plate. I was thinking, using the rezn8r box as a template, of building a box inside the sub box, extending the box up 1 1/2 inches to compensate for lost space and i wont have t-tops, putting a push and pull fan in the back where the speaker terminals are, and putting speaker terminals in the side. Does this make sense? It would be a box for amps inside a slighter larger box with fans to cool the amps. Think of a 8" by 16" by 16" box inside the box. Im not sure if the well is wide enough to still fit 2 12's but im thinkng it may, Im using smaller v power amps and think it would work. I see there's 40 inches on the top of teh box and there shoud be more on the bottom since the subs cone inward. I'll see if i can draw a sketch later.

anyone see a problem? The only problems i see coming is:
1. the box sitting above the well looking out of place
(may be solved by a slanted down top)

2. not enough room between the subs
(but i believe small amps could solve)

3. not enough smace for the subs
(raise the sides and back edge to increase space, may hide hatch light but dome light should be effiicent enough)

Is this a bit optimistic? I think i may need to just get a sheet of mdf and work this out. Maybe this weekend

alright i just did some math, think i did it right. I figured the box the way it is is 2.617 ft squared. putting in a 16x16x8 box brings it down to 1.432. Enough for 2 12's? Adding another 2'' to the back and sloping it down seems to make it 1.703 feet squared. SO for my app, could a alpine type r 12 be okay in a sealed .85 square foot box or worse case .72 square foot box?

wow, no response? Are you guys waiting for me to do it or has tehn been talked about and I not seen it or what? I would have thought with almost 50 views at least one response.

Anyway

well, i answered some of my own questions, an alpine type r 12 needs from .7-1 cubic feet in a sealed box so that should be fine, the amps will be small enough to fit in the box, and now im just waiting to get paid to buy myself a sheet of mdf. We'll see.

Any comments would be nice though

so i guess my only question now is,

how close can you put amps if you're running fans for cooling?

with the box how im thinking of making it, it will we about an inch from each other. One hovering over the other.

by the way, im hoping to be running 2 type r 12 @ 4 ohms with an mrd m1005 amp and the mrp f450 running alpine type r 6x9's and type r 5.25 components with the tweeters mounted in the pillars. Hopefully I dont run out of money before buying the mrd m1005. I may end up using my old v power amp until i can get it.

Umm well I guess ill be the first other one to post and say this sounds like an interesting idea still not sure exactly how you want to do it (its a box right so how are you going to have easy access to amps?) anyways it sounds like an awsome idea especally if you can pull it off, as far as how close the amps can be im sure i will be corrected if im wrong but they can be prity close (like an inch or so like you said should work) when your done get plenty of pictures though i want to see how you pull it off!

You have the subs and amp, you'll just have to see if it will fit. As long as it's not to big an amp it could fit. The only problem doing it this way is it not recommended to mount the amp tot he box. It can easily add to the likelihood of developing box sold connections it the amp. This is vary common, and more so with amps mounted to the box.

I would be concerned with vibration. any not so great solder in the am will be destroyed by the subs "THUMP".

From a technicians point of view having the amp right there absorbing all the vibrations from those speakers you are going to develop connection problems inside in the circuitry of the amp really,really fast.Like I said...from a technicians point of view...

b's90cam

Well, im pretty confident i can get them mounted. Im not worried about that. I am worried about vibration now though. Is there anyway to keep vibration out? Maybe dynamat the inside and outside of the box that will be holding the amps. Would this be enough to cut down the vibration?

tagta189 How long you been a Tech? What do you work on? I've been doing repairs on car audio for quite a few years now, worked on a lot of different stuff though.

b's90cam, you can try using rubber studs, but it's really best to just not mount the amp to the box. Keep in mind tons of people do this and by the time most of them has a problem with he amp, they are read to upgrade any way. But it is a gamble and depends on the amp. Do this with a Sony and good luck having an amp that works for more then a year or two. Then you also have to factor in the new LF (Led Free) solder every one must use. A lot of manufactures haven't quite got the hang of it yet. Time will tell what kind of affect this will have on how long connection hang together.

I've been a tech pretty much forever,worked on everything from audio stuff to high end video stuff.Like the man said,try using rubber mounts.Like the msd ignition boxes use,exactly for the same reason they use them.If you are not too worried about replacing the amp at maybe 2 years tops anyway then go for it.Good luck.

sorry guys, on my way to pick up the camaro i found a 98 z28 that was for sale and picked it up. So, ill be seeing you on ls1tech.
