I know you have more pics than that, man. Show me them ALL!!!

Before you install the rear fill, play with the sound. I bet you will get what you want without ever having to open their box. Matt will attest, Rear Fill is unnecessary

I disagree. Rear speakers are great for my passengers back there. With running only fronts the sound stage is where, at the front. My friends need some vocals back there and not just heart pounding bass in there chest. lol.

I agree with Andy to a certain extent. If you were running active then I'd say for sure you can pump enough volume into the cabin using front locations only. Even though you're running passive I'd still suggest trying it... you'd be surprised how little impact the rear speakers have even for the back seat passengers.

a few months back Matt told me to adjust the stock system so it was all coming from up front. I could hear a difference from the drivers seat, there was slightly less low end, but the overall sound sounded more focused.

I had it set like that for a while and had a car full of passengers some were music enthusiasts like mike self and some weren't. I asked how everything sounded and no one could tell me that there was anything missing. I adjusted it back to completely flat and all they said was it got louder ... then asked me to turn it down.

I'm just saying that with good EQing you can get pretty much the same desired sound without dropping money on rear fill.

Looks good dude. So you just used Roofing material for the membrane. That is an amazing idea. I never realized that they are basically the exact same thing.

It does the same job. With Dynamat they have kinds with a foil face which is prob good for doing the underside of the hood. But there's a site matt told me about and after reading there products the sound deadener membrane they market is just a Butyl adhesive base which is the same as many roofing and weather barrier membranes used in construction. If you do use a construction membrane just read what its made out of.

Asphalt Based= Not rated for high temp applications.
Rubber Based= Holds up better in higher temps.
Butyl Based= Tested up to 400 F, Perfect for doors
EPDM Based= Used on commercial roofs, Best IMO,thick

Like in my pix above under my amps I used a Butyl based membrane, the rest of the cargo area I used an asphalt based because I have 2 huge rolls of it and its being covered by the stock sound proofing. In the high heat with the asphalt based you might notice if you put ur hand on a cut edge the black stuff will get on your hands because it gets soft and its sticky. bad for vertical applications such as doors.

For my doors I have two rolls of peel and stick EPDM membrane used for roof seams and detailing around penetrations in roofs. The stuff is thick and made to be in direct sunlight and will not be effected by heat. Though it does have an adhesive/sticky back side its a good idea to use a primer or even a 3M spray glue for better adhesion.

The only reason I keep mentioning useing a construction membrane is cost, Dynamat and similar "car audio sound deadeners" are overpriced and marked up like 400%, where as construction membrane is sold in huge amounts every day so cost is much cheaper. Im an engineer in the construction field, mainly dealing with weather proofing designs and consulting so I get away with grabbing rolls of it off sites for "testing". lol. To test out in my car.......

Im getting really good at running wires now. Just did my rear doors and took me about 10 min a door. Pop off the weather stripping, pull the interior plastic away at the front seatbelts and the hole to the door is exposed. Pull the rubber boot off the connector on the car body and use an O-ring puller to pull down on the tabs of the plastic wireing connector. I clipped off the lower plastic tab and ran the wire in its place, then just fished the wire thru the boot into the door. I didnt even have to remove the other side of the rubber boot to do this. Then just install everything back.

Just have the head unit and speakers to install now, but its raining out a little. dam it.

Does the XR crossover allow for bi-amping? That would be nice.
