33 Coupe Interior 28        9/25/04

The speakers that will be used in the rear are also made by Infinity. The model I bought is 9603i which are three way speakers and measure 6" X 9" which sounded great when I heard them. I had planned on using an amp to drive all of them but returned it along with the two wiring kits needed to hook them up with. The reason I took them back is because I don't think I'll be using this car for a long distance cruiser, plus the amp weighs a bunch. If it doesn't sound good enough to me, I can always go back and buy it again.
 

 

 

I had to make some minor adjustments to the speaker opening and then mounted them with some sheet metal screws. I planned on mounting these speakers like I did in the doors which means I'm going to mount them in the structure of the car and not the panel that gets covered with upholstery. In case your wondering, I have only one speaker grill installed just to see how it looked. 
 

 

 

This is what it looks like from the trunk side now that they're  installed. I'm going to need to cut the support that holds the floor a small amount because of the depth of the magnets. By cutting holes in the support, this will give me an area for the air that the speakers move a way to pass through between the floor of the trunk and bottom of the car. This area is tapered as it goes towards the rear of the car which should give me a good working system when I'm through. 
 

 

 

To make sure that I keep the noise to a minimum and the sound to a premium, I'm going to use this insulation on most of the car. This is made by B-Quite and is called Brown Bread (go figure). Brown Bread is a viscoelastic deadener with a bitumen based adhesive (looks like and gets you dirty like tar) and sticks like you wouldn't believe. With an aluminum constraining layer and a unique composition with suspended mineral particles it has been proven to be extremely efficient at the conversion of vibration to thermal energy. Brown Bread is extremely flexible which is very important as it allows it to properly adhere to a contoured panel. It can be installed anywhere including under the hood. Brown Bread is 1.6mm (63mil) thick, weighs 0.4lb/sq. ft. and comes in 2 foot wide rolls. The only problem is that the weight adds up fast so I'll have to be careful using it. It also came with a roller which is a hardwood roller that makes the installation of the material quick and easy and insures that it sticks properly. Once this stuff is stuck down, it's very hard to get it back off which is a good thing.....right?
