I'm looking for some infomation. I'm thinking about adding 2 10" subs in my 95 STS. I was told by an installer that because the trunk is realy sealed on STS's that the bass will hardly come through out serious modification to the trunk. I think he is full of sh** but could use some input from other STS owners with systems.

Well look at your turnk and back seat. I know nothing about the STS, but if there is no space between the back seat and the trunk anywhere, and no where else for it to come through, then he is right to a certain extent. One thing that helps bass out here is you don't just hear it, you feel it :)

I would say he is correct. Straight from the factory the do what they can to minimize road noise. Ussually there is quite a bit of insulation on the floor of the trunk and also near the back panel or seat in the trunk also. They do have a think layer under the rear deck. All I did was cut a rectangle in the rear deck and then custome made a panel with some matching grille cloth. Helped with the bass and also helped with distortion of the rear speakers.

I took the 6x9 out (they only serve as woofers), leaving the holes covered with the original grills.
I have great bass.
Cadi 179's is an option I considered as well.

cadi197,

Do you have pictures? That sounds really cool.

Diablo, that's a really good idea. I would say that someone not wanting to do a lot of cutting, etc. should go that route.

Bass is going to go somewhere, if it were sealed you would be poping the 6x9s out of thier holes so the pressure could escape. Do what Diablo says it seems to be the best idea.

The only thing you need to do is to remove the 6x9's and the piece of lining that covers them. Best part? If you need to sell your car, it will take you 125 minutes to leave it exactly like it was.
