Hey everyone I just got a bunch of my audio parts in today and I am going to be putting a fiberglass enclosure in the back right corner of my boot for my new slimline sub.  The install includes the following list of items:

• (Refurb)Kenwood KDC-352U
• Boss Audio R1100M Mosfet 400watt Amp
• Rockford Fosgate R2 Ultra Shallow 10inch sub

​I already have speakers installed in the car with a 4 channel amp but I think I will be removing that amp and just letting the headunit power the speakers.  I put my first layer of fiberglass in today but it got too dark to take a picture of the laid first coat.  More pictures to come as I move forward.

 

Headunit:

Amp and Sub:

Half way through laying protective trash bag mechanism:

Completed protective coating:

Day 2!!!

 

So today I did a lot!!  I got pictures of as much as I could.  I put on another 1.5 - 2.5 coats of fiberglass resin on the mold today.  The shape is made though which is awesome!!  I will be trimming it a bit more once I start making the final shape.  I also lined the entirety of my mini's interior with B-Quiet sound dampening mat.  That marks the first layer of sound deadening complete.  Next will be jute mat across all the surfaces that are not visible.

Nice! I will be watching this, always fancied doing it in my mini. Wasn't worth it tho seen as the boot floor was rotten!

 

Will be a good "how to" though!

Thanks!! I would definitely recommend taking the boot lid off if you ever do decide to do this yourself.  It was a pain to work around.  Im really excited for this to get finished.

Day 3 Update!!

 

Today I took a step away from the fiberglass mold(because I ran out of fiberglass resin) and I moved on to do some rewiring in the car as well as finalizing some more sound proofing.  Take a look below!

Amp Conceled above the boot under parcel shelf and jute laid in the back:

 

And My 2 pack of rings for the sub enclosure:

Don't mount an amp face down...
It will over heat as the heat will have no where to go but back into itself...

You're being sarcastic right?  Hahaha I have mounted amps upside down many times.  You're original fiberglass build was actually the one that pushed me over the edge into doing this.  Thanks for the idea!!

He is right, to a degree. You would have to push the amp pretty hard to get hot enough for the heat to have an effect. 

 

Practical advice I would say is to check the temp of them after driving and using them for a reasonable period of time. If they do feel very hot or hotter than usual move them. If not they should be fine.

Nope.

That doesn't make any sense to me.  The cooling potential shouldn't be effected by the items orientation.  You computer wouldn't cool any less effectively if you flipped it upside down.

I could go on.

The problem is heatsoak, if you usr a fan to move the air away from the amp it's should be ok. But I wouldn't do it to be honest unless I had no other options.

I have Rockford Fosgate, DLS and Genesis manuals that all specifically state to never mount amps this way.

Thanks for the information that is really helpful.  What do you think about flipping it so its vertical on the back of my read seat?  Should I still worry?

A PC has active cooling, most amp are passive and uses the natural convection of heat to take heat up and away from the heat sinks. But if up is the heatsinks where will it go? It can't go anywhere so it builds up and up... heatsoak.
