Does anyone see a problem with this?

[Mickm]

Hello,
I am about completed with the install of the Hotchkis suspension but am awaiting return of the steering from FirmFeel so I decided to build a location platform for the amps and rear sub woofer between the rear seat the the trunk.
 
I have the platform suspended with a large cut-out in the plywood beneath both amps to allow air access. Everything is very snug and seems to fit properly.

I am just wondering if anyone, who know more than I do about stereo installation, sees any reason this shouldn't work.


This is the assembly out of the car and on the floor. It is quite easy to remove and re-install.


Here is the assembly with the amps and what-ever they are in place out of the car.


Here is the assembly installed in the car.


This is similar to what I have it mind for the trunk interior.

All input is appreciated

Cheers!

About the only thing I could see is air ventilation.  Maybe some 12v computer fans to circulate air through the enclosure.   Around here surplus stores sell them for a few bucks a piece.  You could even wire them to a thermo switch

Just thinking those amps throw a lot of heat,  is your sub in a ported box?  That may help with air circulation too

Hi Gyman98,  That is exactly why I asked this question.  The sub woofer is in it's own enclosure. It was longer on one side so I cut the box down so it would be symmetrical.
The computer fans are a great idea. I did leave room beneath the amps with an air cut out on the floor bottom but is this enough? Originally, the amps were mounted in the trunk on a board facing into
the trunk. Now they will be in an enclosed area  but I do plan to leave the wall in the trunk with two large openings with screen over them to allow air to get in. But, they are still in the enclosed trunk.
Thanks for the help.

Cheers!

Your Amps should have thermal protection but best to avoid that

What I meant is your sub box ported,  sealed, band pass etc?   If it's ported that will help with air circulation due to pressure/de pressure/pressure cycle of the enclosure

[Mickm]

Gyman98, I am obviously confused. You mean the amps are not what I need to worry about overheating (because they have built in protection)?
But rather the 12" speaker enclosure is where to be concerned? 


This is what it looked like when purchased from Kicker.


This is a photoshopped photo of what it looks like now.  I removed about 3" or so from the one side so as to make it symmetrical and look proper in the plan I have in my head.

The box is sealed (completely enclosed) with some form of thin padding inside.  Do I need to put air holes in the box for ventilation for the speaker?

Thanks for all the input, I am obviously lost in the world of electronic gadgets.

Cheers!

where are your groceries and golf clubs fitting hahahaha

[Mickm]

well wantone, you pose an excellent question!  Before, I could get mine and my wife's golf bags in the trunk but it was full, so that won't happen now.
I guess we'll have to take her SUV...............not cool..............!  lol

I think it will work...

But question is , was it a sealed. 12" sub enclosure ?   Or did you cut off the venting when you reduced its size?

Are you running  4 channel amp for the speakers and a single channel for the sub?


Are you looking for mild subwoofer bass ? Or here me down the street bass?


Framework looks nice so far

In my opinion the box should of stayed the size it was as that probably was the minimal size cu ft for that speaker.  Boxes are always designed to be properly sized for the specific speaker.  As far as ventilation if heat can escape at the back deck I think your ok.  I used to play with that stuff years ago.

Correct, those subwoofer boxes are (or should be) tuned to fit the bass element and by cutting it off you will be tuning the box to a different frequenzy that might not be ideal for that bass element, it might sound thin. If you are gonna mount a wall like that Camaro, you might not need a box at all, the trunk will be the box, but its a trial and error procedure to make it sound right. On the other hand, you might be lucky and it can sound good as is also.


I'm gonna do something similar when the time comes on my Challenger, I had a -05 Mustang with a big subwoofer box on one side of the trunk, a stock Shaker 1000 system, that sounded very nice. And didn't use too much space either.

[Mickm]

As an engineer I would believe the box was designed to work at it's best frequency with that speaker. The box was completely sealed before I cut it and it is sealed now. I could have left it as it was since it will  be covered with the partisan but the OCD in me wouldn't let that happen;
maybe a mistake.  I will leave it as is until I get it wired up and then I'll see if I like it or what I need to do.  I was most worried about the heat but with the amps not the speaker. Just shows you how little I  know about these things.

I am looking for a nice sounding system, I do like some bass but I don't want people to hear me coming before they see me either.

Thanks for all the input guys, it is greatly appreciated.

It will be fine,  subs in a sealed box usually come with a minimum box size but all you do is loose some performance with a smaller box.  Sealed boxes have the best sound in my opinion,  nice and tight.
