First what size is it and did anyone ever replace it with an aftermarket sub that was powered from the bose system?

 

its an 8", thats all i got

 

Oh ok so I guess it's defenitely replacable, just wondering if the factory amp can push an aftermarket sub?

 

it probably can but the sub wouldnt be operating at the power it's capable of

 

Thats what I was thinking too just wanted a second opinion, thanks.

 

I dont know if you have seen how the bose sub looks, but it is some odd inverted design and has the amp built in.

Oh my old ford, I ran an aftermarket sub off the factory sub. I had to hook up a line output converter to sub signal AFTER the amp because the in signal was too weak. But keep in mind, your sub will most likely be opperating between the frequency constraints of the bose sub since that is what the system was designed to provide a signal for.

 

Thanks for the advice I'll keep the system stock for now

 

Also, the BOSE sub is designed the way it is to function in the rear deck enclosure using the trunk as a kind of "box". I think an aftermarket sub in the same enclosure would sound like crap.

 

Unless someone knows of some very efficient free air sub?

 

Yeah I was thinking of replacing my Bose sub too. The sound is kinda funny. When the bass is turned up even a little, it sounds like theres some weird vibrations going on that arent just comin from the sub itself. It sounds horrible. I was wondering the same thing, if an aftermarket sub can just replace the bose one without having to modify the amp, enclosure, etc. I guess not.

 

One quick answer. no. the only sub that is reasonable free air was a image dynamics i think....8"....discontinued now. this was after about two months of looking. i ended up going with a box.... i was about to drop the money for an 8" W7 but that is not a free air/infinite box sub....also i would never power a aftermarket sub with that amp....also someone else already said it....the amp for the sub is inside, behind the magent of the sub....that black box is the 4 ch amp for the speakers.

 

Your problem seems to be the dreaded 5th gen rear deck rattle. We all have it and either put up with it, or fix it.
