Title: sub in the boot floor? suggestions/advice
Post by: cняis on 18 February 2008, 16:38

i have an unbranded bandpass sub box with 2 x 10" subs, which causes 2 problems:
1. its a large box and doesnt provide me with much shopping space in the boot.
2. it creates a LOT of bass, i.e. it will give you a headache but its not overly crisp/responsive (drones a bit!) - i think thats the nature of bandpass boxes.

as this is for the project golf, which will see limited milage, i can do away with the spare wheel. i'd like to make a false floor (mdf) in the boot and mount the a sub over the spare wheel well. will this:
a) sound ok?
b) need to be ported?
b) mean that the wheel well needs dynamat (or similar)?

im not after a show winner, and i would like to re-use what I have already. im just looking for value for money.

With any sort of build like this sound proofing is good idea and you would probably end up having to make a false boot floor to create enough space to fit the sub, I would try and find out how much space the subs you have need to try and get the best sound out of them. I have no idea what it would sound like and I wouldnt worry about porting it as the chances are you wont be able to make the space it'll be in completely air tight.

go for sealed as box size will be smaller.

sound proofing is a good idea.

sound quality can vary from so many factors so hard to say but should be ok ;)

Agreed. I'd also go for a fibreglass enclosure.

I'd initially thought about going this way and having one of those bottle repair kits instead of the spare. I've now gone against it and started a side panel moulding off. Bl00dy messy, but I'm hoping it'll be worth it. I'm going for a sealed rather than ported box to keep the bass tighter. :cool:

I would FG the spare wheel well, then keep going up with the false floor until you have the desired volume.

a lot cheaper solution would be two of these:

under drivers and passenger seat mounted flat

just an idea to save time and money
