Hi, I want to install 2 10" subs and a amp. The only thing is there isnt much room in the cab. I was thinking of doing the following:
Cut 2 holes in the rear wall of the cabin and placing the subs in there. On the outside of the cabin i will put 2 boxes covering the subs. Then u know fix it all up so it looks good. I was thinking of 2 aluminium boxes covering them lined with wood on the inside so its not a "tinny" noise

Tell me what you think and if anyone has some suggestions please let me no.
Thanks
Jack

i was thinking about doing the same thing but with a 12 inch sub. The problem i found is the "ripple" in the back wall will not seal easily and make for a reduced quality in sound.

I was thinking of building a sealed box in the back and then porting it through to the cabin.

I was going to weld a brace in the back aswell just to make sure i dont loose any structural rigidity.

Furthermore you could always use an Alpine Bass engine if you only want the vibration the subs make. will fit nicely under the seats.

Thanks for that. Anyone else got some ideas?

how badly do u need a sub or 2?
i too have a a ute and i too thort long and hard about a sub. in the end i think that a sub isnt neccessary in that small of a cab.
wot i did was got a 2 channel amp, alpine type X splits and run about 200wrms through each speaker. if you put hte tweaters up near the windscreen u will get a more even sound than if you have 2 subs in ur ear draining out your speakers donw in the door panel.
but if you really like to feel ur music, then a sub must be the go!
i thort about this, and i too came to the conclusion of putting them in the back wall, but u then have to fabricate a box, get an engineers cert coz u cut out metal from the chassis.
an alternative is to put the sub at the passengers feet. in the footwell. or, bcoz these things dont have entre consoles, u mite b able to squeeze one on there.
but i reckon that if u amplify a good set of splits, u will come out with better sound quality and less hassles

I agree with you that it would be easier without subs, but i recieved these as a gift and i will get them in somehow. I might fabricate a box behind the cabin and then cut the wall.

well if youre really keen on 10 inch subs then this is the only way to go. good luck. let us know how you go.

Cut a hole in the back wall about an inch larger than the correct size. Weld in thicker metal to fill in this extra inch, about 1-1.6mm thick so it sits dead flat with all the ridges in the back wall and build your box around that. Structual rigidy plus good sound. Its not hard to do.

What do u think i should put int the box that sits out the back so the sound sounds good. Cuse i belive the metal will just vibrate alot? Maybe foam or something

I would make a complete MDF box for behind the wall. And cut a hole the correct size in the metal ( no engineer needed as no chassis getting cut ). I would also make a MDF plate for inside on the back wall. I would mount the subs inside the cabin and screw through the inside wood, through the metal and then into the box. I would seal the inside wood and the box against the metal wall with sillicon.
You can cover the box anyway you want really.

Thanks alot for that good idea
