I was thinking of getting 2 8 inch subs and puting them in the stock locations of the 6 1/2s. I could dremel out the rest of the hole, and put these in using the stock wires, and an aftermarket amp to get the necessary power. Right now I have alpine door speakers, and a pioneer head unit.

If you think this would work, which subs should I get. I dont want to add a sub somewhere, but I am tired of the 6 1/2s limited travel!! Thanks.

Feel free to say it is stupid, because I know nothing about speakers, and stereo. :haha:

 

i dont know if an 8" would fit in the hole... there are 6.5" subs too, but i am not sure how you would do an enclosure.. (i looked and atleast the rockford fosgate 6.5s are not free-air..)

 

I am talking about making the hole larger. I measure the stock one, and it measures almost exactly 8 inches in diameter in the embossed area that the subs are in now.

 

the problem would be depth... whats the depth available?

the 8" rockford fosgate has almost a 4" mounting depth... my 6.5s are less than 3"..

another thing to think about is that most subs require an enclosure.. that would probably be the most challenging part to do.. it would almost surely have to be fiberglass and custom. it probably can be done, but it would be difficult.

 

Yes, it can be done. I asked about it at a local car audio store in my town. Would have been a GIGANTIC pain in the *** though. Totally coustom fiberglass encloser, lots of fabricating, lot's of money, and it won't even sound as good as if the subs were in the very back.

 

Has been done many times, You just need some free air 8's, if you can find some Jl 8ib4's they will fit without a problem.

 

Hey, Camaro SS... I've installed a pretty substantial system in my T/A, and I flush-mounted a processor in the passenger-side sail panel location, so I've ripped apart that area of the car. my site: http://www.snootch420.freewebspace.com/ Stock, there is a 6.5" speaker mounted directly to the metal. behind that, there is a large hollow cavity above the fenderwell leading into the inside of the body panel. There are two ways of getting 8"s in there. Solution #1:

Get a sawzall, and cut a 8" square hole around the stock speaker opening. Cut a 9"-10" square panel (with one corner cut off to allow for the wheelwell) out of MDF, with a 8" mounting hole for a Infinite-Baffle type of subwoofer cut into the middle of it. Seal the baffle to the metal of the car using RTV and screws. You might want to sound deaden the inside of the cavity, and the metal surface as well. Very important: Use a IB type subwoofer for this! if you use a regular type of woofer, the suspension of the speaker will bottom out, because the enclosure made from the body of the car isn't sealed airtight. IB subwoofers have stiff suspensions to compensate for this.

Solution #2:

Get a sawzall, and cut a 8" square hole around the stock speaker opening. Get some Great stuff spray foam and fill all the metal seams with that. Then, paint the cured foam with some house paint or something to seal the foam, and keep the fiberglass resin from melting it.When the paint is dry, Layer 3 or 4 layers of fiberglass on the inside of the cavity, making sure that every surface is covered well. Mount a plate as described above in the IB install, and fiberglass onto the inside of the plate. Make sure that all the fiberglass is thick and strong. Mount any 8" subwoofer to the MDF plate. The enclosure should be airtight.

As you can see, the easiest install is the IB install. If you find some good IB woofers, at least a 100wx2 amp, it should sound fine.

 

Damn I am sooo lost! What is a IB Subwoofer? :haha:

 

i believe he's talking about a sub designed specifically to be free air... it doesnt have to have an enclosure

 

I was told that free air subs suck, and don't hit as hard or sound as deep as one in an enclosure.

 

Yes that's an unfortunate trade-off of not having an enclosure.
