Can someone who's mounted an SUB in their parcel-shelf or whatever you want to call it give some feedback on sound quality?

I have sussed it out and there really isn't much clearance at all between it and the rear window. Usually it wouldn't matter but does having that much glass so close to the sub make any difference?

Thanks.

yea if you want to attract thieves

LOL

Putting it close to glass doesn't affect the operation but I would personally not consider it practical.

First point has already been covered by blkGT. The second is the hot summer sun. Glass wont keep the heat, but it will certainly let the heat through. Best to keep the amp in a nice dark cool place

Sorry dude... I was speaking from experience as I had mounted an AMP to the parcel-shelf of my last car (Nissan Sentra). No impact whatsoever to the sound quality because regardless where to put the amp - its output would remain the same. If you meaning sound escaping from the bootspace due to the mounting then again - depends on how big a hole you're making to mount it. I would say usually there is no difference unless you have the hearing of a hawk to distinguish a drop in dB.

On the plus - if you're simply placing the amp on the shelf, it would actually add weight to the damn thing so no more "thud" noises when you go over a road bump

nah, amps would run WORSE under hot conditions.

Shhhhhh.... you have to reply to the specifics. I've already said heat is not good for it!

the sound quality would be worse because of poor performance due to being in the sunlight

I so agree!!!! My Nissan sounded crap until someone told me what a dumb-@ss I was... then I said... "Yeh sweet... I'll put it in da boot" - and then it got nic'd

BTW blkGT : I read your post bro... sorry to hear what happened. Personally I would make the clown eat the amp then make him buy you a new one.... then hand him over to the cops.

Now what if you were to tint the windows, make a hole in the shelf so that the amp is sunk in, and then create a sleek cover for it so that it's not seen, nor directly hit by sunlight. What would you say to this idea? Would it help keep it cool, or would it make no difference?

Just mount it on the underside close to the seats so you add the least amount of weight to the shelf, its out of the sunlight, and out of the way.

Guys I would plan on mounting them onto the shelf then covering the whole thing so sunlight wouldn't really be an issue. I wasn't worried about rattling from the shelf I would reinforce it, just basically the angle the subs would be and whether that would affect sound. I've only really messed with big subs not car stuff, and they can be touchy with bad layouts..

send the subs backwords and your subs will pound regardless of where your amp is located - next time call the thread "how should i angle my subs"

Putting amp on top and covering is going to be bad for the amp as well.

Underside = less performance as well. Heat rises right? Then then heat would go out the top from the heatsinks and then back into the amp because its upside down.

My best suggestion is mounting on the back of the fold down seats (if thats the style your going for). Personally mine is in the middle of my trunk.

Ya heat rises but its a trunk not a freaking biosphere. The temp on the bottom of the trunk will be about the same as the top. Anywhere you put it in the trunk it will be cooled about the same.

But kamax putting it up top and covering it will probably make it over heat even worse. Its freakin hot in the back between the shelf and hatch lid. So ontop of the heat back there you'll be trapping the operating heat inside aswell. If your just gonna cover it then just put it somewhere else?

Sunlight will be an issue aslong as any is getting through the hatch window period. It doesnt matter if the amp is covered or not.

I made a custom shelf from 1 inch ply, cut the middle out, topped it with half inch and mounted the amp to the underside. it means i still have trunk space and the amp cannot be seen from the outside of the vehicle. (if link doesnt work just check my profile)

that = phat

Ya dude thats clean for sure and pretty much what I was thinking, just alot cooler

Goddamm maybe I should have named this thread "SUB(s) mounted in hatch shelf?, has anyone done this?"

In my retardedness I mistyped and wrote amp instead of sub at the top Hopefully that should clear some confusion up.



Fintan that is awesome, and something just like what I want to do.

If I didn't mind about using space up in my car I would just throw the subs in an enclosure in the back seat or boot, but I want to keep the car as usable as possible - that means being able to lay the seats down if I want, and having full boot space. Can anyone think of a better spot than the shelf? I could replace the rears with subs but I'd rather keep em. And building glass enclosures around the back corners is a cool idea, but you the jack space and stuff.

My Q has been answered in a roundabout way .... so thanks for that, but as I said I actually mean the subs, so obviously the heat won't make quiet so much difference as what you were all saying. Atm I am planning on mounting the subs in a similar type of shelf to Fintan, with the amps (1 for rears) under the front passenger seat.

Cheers man, glad u like it. I use my car every day for work and with the sub box mounted to the side it takes up hardly any room and i can still drop the rear seats. If you are looking to mount the sub in the rear shelf you would have to use a "free-air" sub unless you build a big ugly box hanging down into the trunk. they drop in just like a speaker and use the trunk space as an enclosure, but you will have to reinforce the shelf with ply or mdf, or better again make a whole new shelf!!!
If you were worried about people being able to see the sub through the rear window you could cut the hole in the shelf, mount the sub to the underside and then carpet the whole top with an acoustic felt. just remember to leave a few ribs in the cutout to support the felt otherwise it will collapse and to anyone looking in it would be a dead giveaway. hope this is of some use to you, best o luck.
