I just finished a fiberglass box for my wheelwell, but now I'm not sure what I want to do with my amp. It's too big for the back of the seat [and that would defeat the purpose of the pass-through which I wanted to keep]. The only thing I can think of is to mount it from the top of the trunk, either upside down with cooling fans, or right side up with an inch or so space for air [and perhaps with fans that way, too]. I have no welding abilities or eq what-so-ever, so I was hoping for ideas. Anyone?

Thanks,

What amp is this? Dimensions? Too big for the rear of the back seat? Amps can be mounted upside down, but if it's too big for the back seat, I don't think you'll find too much more room on a trunklid. Can you build up a little more for a false floor? You've already lost that spare...

 

Actually, I put the sub on the right side of the trunk, over the wheel well, all the way up to the end of the trunk. I might look into building down into the false wooden floor, but I'm not sure of the space, with the spare there. I don't think I want to put the amp on the trunk lid itself, that just seems like it would get jostled quite a bit every time you open or close the trunk. Rather I'll mount it to the top of the parcel [is that what it's called], between the parcel shelf and the trunk lid.

It's a Memphis Belle [MC1300d I believe]. It might barely fit on the two back seats, but again, I don't think I want to do that either.

Any ideas on how to mount it to the trunk ceiling?

Try L brackets and mdf to the back deck ceiling. Most amps in the directions tell you not to mount it upside down because it almost defeats the purpose of the heat sink; heat rises, etc,etc. Cooling fans with it mounted upside down might work but I wouldn't risk it, especially since it's summertime; that would be overheat city.

 

I would check with the manufacturer to see if it is ok to do this with your particular amplifier. Some of the amps I have owned had also stated not to do do this.

 

http://forum.elitecaraudio.com/showt...6&pagenumber=1 is a topic on just this. If you read it, pay special attention to the posts by Slick, as he's been running amps upside down in his daily driver for years. If you wouldn't be having big heat problems otherwise, I'd think it would be OK.

If you're still apprehensive to try it, I guess you could drop a shelf down from the rear deck and mount it normally, but I'd guess you'd be OK upside down if it's close to the old school Memphis Belle I used to own....the old 75 x 4 + 150 x 2 at 4 ohms (non class D), that thing was a beast and got warm at the worst for me.

 

i heard most amps will run better when mounter vertically opposed to flat aka horizontally. i really dont see how there is that much difference, but the heat sinc and runnin it upisde down makes good sense

 

I'm not too worried about running it upside down, putting fans on it should help either way. Any suggestions on how I mount brackets to the ceiling? Is there a liquid weld type substance I can get? It looks like it could be tough to get a nut between the sheets of metal to bolt it up. Any other suggestions?

Thanks,
