Does anyone have an aftermarket subwoofer mounted in the stock bose subwoofer holder/bracket?

If so how does it sound and what kind of sub do you have?

Thanks

 

anyone?

 

You can do this ( I almost did!!) but how it is achieved depends on the type of sub you use. Some subs WILL require a enclosure be built to house the sub, while others are open firing. Check the threads and you will even see the calculations done for the cubic feet needed for various size subs!

 

thanks

 

You will need a free air sub for it to sound right.

 

or a custom fitted fiber box w/ a bit of dynamat surrounding the outside...

 

I assume you have a convertable....i installed a sub in the bose hole. I just used a sub I had and it didn't fit perfect as the sub seemed alittle small for the opening, I almost didn't have enough meat for the mounting screws. If your hed unit does not have RCA outs, you have to buy a electronic unit (from a stereo installation shop) that taps into the rear speaker wires that has RCA outs so you can power the sub with an amp. YOu need to power the amp from the battery and get a signal wire to turn the amp on from your existing head unit when you turn the stereo on. Put your amp in the hole and adjust your gains before you install the sub. Cut out your stock plastic cover for the sub, and cover it with speaker cloth using a glue gun to attach the cloth. Done, and enjoy. Ok its not quite that simple but its worth it. Gord

 

Any pics of your install racenu?

 

Yup... I did this 3 years ago. Dynamat the insides and seal it with polyfoam spray. Cut an MDF board using the plate as a guide and bolt it in place of the OEM Bose plate.

I recently swapped my JL 10W3 V1 for a V3 and retuned my system. The bass is so deep I couldn't believe a 10" could do that. Ah don't forget... I used lots of silicone caulking to reduce air leaks. No noise!

 

I'll take some pics this aft and post em if I can figure out how, from what I was told all subs are free air?? if you build the enclosures and port em they will sound tighter but when you have the top down how good can it be? The only suggestion I would have is it would be nice to be able to adjust the gain on the sub from the drivers seat as some songs need more gain than others and I believe some amps allow you this feature with a remote gain adjuster? good luck, the biggest prob with this install is figureing out which wire from your head unit will remotely turn on your amp. I used a wrong wire from the head unit and it didn't put out 12 volts, so I was screwed up till i figured that out. Use a volt meter or a good test light to determine whether you have 12 volts to turn on you amp. ttyl gord

 

No, not all subs are free air, if you do not get a free air sub and it's not in an enclosure, you will not get the bass you wanted. Certain subs are made for certain size enclosures so check the specs before you decide on one.
If it's too muddy, you can tighten it up with fiberglass house insulation, you don't need much, just line a couple of the walls or just the back wall with it. Also, check some of the old posts, someone put his amp in the hole and actually put some long screws into the gas tank. Luckily he didn't have a fire, but be careful if you mount the amp down there.

 

well, remmeber free air doesnt mean the sub doesnt need an enclosure, it just means the enclsoure can be extremely large. its still important to make sure hte space infront of the sub is sealed off completely from the space BEHIND hte sub...

meaning, you cant just put a free air sub on the floor, sitting there, and expect it to be able to produce any bass

heres my attempt at attaching the photos, I'll have to do it a few times as I think the files are too big. This is by all means not a pro install, I have the amp tie wrapped in the hole just so it doesn't slide around. As someone else mentioned be very carefull drilling and screwing and I wouldn't recommend screwing or drilling a blind hole.

heres a pic of our car, it was a theft recovery from california, its new home is Canada...we added a spoiler, 19 inch rims and tires we love it, good luck with your install. I got alot of good info from this site with regards to taking the dash out plus tire and wheel selections, Gordon
