Sound deadening my jeep - pics & results

Hey, this is my first post but I've been a member for a few months. This site has been a tremendous resource for me, and I thank all of those who contribute.

I've always been a fan of proper sound deadening. I've deadened the last 3 vehicles I've owned and in all cases, the results were nothing short of phenomenal. My TJ however, posed a new challenge for me though... she's loud, clunky, and basically transparent to outside sounds in general. Like a lot of folks, I wanted to have quality audio, with the top down, at highway speeds. In an effort to keep this write-up on topic, I'm not going to touch much on the audio gear that I decided to go with but basically I firmly believe that you can get ultra high-end (high $) sound out of a decent setup if you deaden. It's MUCH cheaper to properly deaden, than to overcompensate acoustic challenges with high-end gear... much cheaper.

The product I chose to go with this round was RAAMmat BXT and Ensolite, both offered by Rick over at www.raamaudio.com. His customer service is unmatched and his products are great. Engine noise was a huge concern of mine and I asked Rick his opinion with regard to using a layer of BXT on the inside of my hood. He straight up told me that he doesn't endorse his products for the engine bay and suggested I go with Dynamat's hood liner. Of course, I didn't listen to Rick and ended up laying down a layer of BXT anyhow . I used the Dynamat hood liner on top of it. After nearly 1k miles, there is no peeling or weakening of the adhesive and at idle, I can barely hear a faint hummmm coming from the engine.

Ok, on with the pics:

Rear seats and carpet removed, area cleaned:




Shot of BXT down and then Ensolite, doubled the BXT in the very rear because this area will be facilitating two 10" Alpine Type-R subs:






Here is the rear door with a layer of BXT, then Ensolite:

Shot sequence of the door being treated. In this case I've got a layer of BXT followed up with Ensolite. I also took the time to give the door panel a good scrubbing and then treated it with McQuires "back to black" which is a plastic treatment intended to restore faded, black plastic but I've found it works great on all plastic.







Here you can see where I've utylized the 5.25" bracket adapters offered by 33 Engineering to mount a set of Alpine Type-Rs. Notice the deadening in the background. I also used a piece of BXT on the speaker cover, attention to detail like this really pays off in the form of zero rattles once everything is done.

Here, I ran up on some rust... I decided to treat it using Por-15. Fortunatley they have a starter kit for around $18 that was more than enough to treat this area. In the shots you can see, before > prepped > treated. The results was rock solid, this stuff is serious sheeeet.






These are various shots of the floorboard and inside firewall, ignore the wires hehe:

Here is the inside of the center console, notice the spot treatments of BXT:


And lastly, here is the hood I touched on in the beginning of the post:


We'll, the results far exceed my expectations! I've got a great sound stage that is retained even with the top down on the highway. The inside while running is quieter than my sisters 06 Scion TC... MUCH quieter. There are a ton of dynamics that come into play with sound deadening and how its advantageous but I HIGHLY recommend it and again, if you have any questions, post em up.

Thanks Adrian, I didn't do the inside door skins only because there are no speakers in the door panel. Deadening my doors really help a lot with tire roar and added a lot of depth to the audio, everything sounds really rich and full if you you know what I mean. I didn't baffle the front speakers, I thought about it but figured since I am running about 90w to each, they would do fine free-air and not get muddy. I have a set of type-r 6.25 behind the front seats as well using the quad-pod (2 speaker version). The sound bar, although still attatched, serves only to hold the interior console light ;o).

Are those front speakers -

Alpine SPR-13C 5-1/4" 2-way car speakers (power range: 2-90 watts RMS (270 watts peak power) ?

If so, do you like them and what amp are you using to power them.


I have the Polk db525's all around with the F250 Alpine AMP...and it just doesn't meet my need for volume. Quality stuff - by all means - but not enough volume for me with the top off.

Yeah, they are. I love them. I went with the alpine mrp-f550 which is rated at 90wx4 @ 4ohms. For the 2 type-r 10s in the back, I opted for the MRP-M850 which is rated at 800wx1 @ 2ohms. I got both amps and the 2 10s shipped for just over $700. It's THE MOST bang for the buck I've ever had concering audio gear and with the deadening it easily sounds like a multi-thousand dollar setup. Actually, my goal, was to spend no more than 1k TOTAL for the entire project, including deadening but I overshot that by about 400 bucks. That includes the custom box, all wires, etc.

Sorry, I forgot to include where I got my stuff. Most of it came from zigiboom.com (speakers & amps). I caught a sale on my deck at crutchfield believe it or not. The rest of the stuff (distro blocks, wiring, 1 farad cap, etc.) came from sonicelectronix.com. The deadening of course came from Rick over at www.raamaudio.com

How much "stuff" did you need to do the sound deadening? Can you post a supply list and total cost?
