I'm in a process of replacing the Bose sub with a 10" RockFord Fosgate Type R. I took out the Bose sub and put dynamate inside of it and when I tried to mount the Type R...it doesn't fit cuz of screws holes didn't match up with the cover. Any ideas on how to mount it?

Also, do u guys think it will sound better if I just buy a 10" box and mount it in there and put it behind my trunk instead of replacing the Bose sub?

Thanks

 

The Alpine Type-R subs require a sealed enclosure. Unless you go in and seal EVERYTHING in that space behind the drivers seat, it won't perform correctly, and it'll sound crappy.

Additionally, the space behind the seat is probably much larger than the optimal space for that sub. Look at the spec sheet for the sub and find the recomended volume for the box and either build one of buy one.

I have a 12" Type R in my trunk, and it sounds REALLY good. I've heard that putting them behind the drivers seat doesn't give them enough room. Try putting it in the trunk and pointing it at the glass of the hatch, and it'll improve the sound a LOT.

 

you could fill the excess space with sound insulation and make sure that all the holes are sealed and dynomated and it should be fine.

 

How are you going to power it?

 

You cannot power that sub with that junky/wimpy factory Bose sub amp (fits in the palm of your hand)--unless you want to blow the speaker. It will not supply the power needed to push that sub. Also, you will have to completely seal off that factory sub location for that sub, or use a freeair subwoofer. However, I have yet to hear a freeair sub in that location that did not sound like DOO-DOO.

Always remember--"no highs, no lows, must be a Bose"

 

I'm using a rockford fosgate amp to power the type R sub but when i tried to mount the typer R, the screw holes on the type R didn't match up with the cover of the box behind the driver's seat. I'm thinking about drilling holes to mount it. Any ideas of how to mount it?

 

youll have to drill the excess out of the holes on the sub (drilling so there is more room toward the rim of the sub). there simply isnt enough surface area of the stock sub enclosure to match up with the mounts on the sub. i know that these are expensive subs and you wont want to drill on it, but this is really your only option if you mount it properly (or as close as possible) in this location. if you do this youll have to use different mounting hardware than usual, or drill out the lip of the sub where you extended the holes. of course youll have to drill extra holes in the sub enclosure too, but it will work. if you want i'll post pics either today or tomorrow on how i did it.

 

ajk4, can u please post some pics so i can get a good idea of how u did it? Thanks!

 

this pic is totally out of focus, and the drilled hole hasnt been "cleaned up", but you should get the idea.

 

So how do you connect the aftermarket amp to the Bose system?

 

you could use an loc, but i would trash the bose hu, cause by far its the weakest link in the chain.

 

So can you or not replace components of the Bose system? Do you not have to replace the whole thing?

 

yes you can replace any component of the bose system while still using the bose hu. all you have to do is convert the signal from the hu using a line output converter so you can connect an aftermarket amp to power the speakers you are replacing the bose speakers with. however, you can use the bose hu and crappy amp(s) to power them but it wouldnt sound very good (if the replacement speakers are of the same ohm rating as the stock speakers). at first, i just replaced the stock sub, but soon grew tired of the audiopilot volume adjustment crap and ditched the hu altogether.

 

So then could I keep the entire Bose system intact and just add a sub and amp for powering the sub? how would I do this without changing any other part of the bose system?
