'04 Audio Upgrade/Sound Dampener

Hey all, back in 2013 I posted about doing some audio upgrades to my '04 CRV LX. First I'll touch base on those.

I installed these Kenwood components up front http://www.amazon.com/gp/product/B0037PH2CY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 and these Kenwood speakers in the rear doors http://www.amazon.com/gp/product/B00HZVJLKM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1. In hindsight I wouldn't have bothered with new speakers in the rear doors because I only use them as fill. To go along with these speakers I installed a new head unit. Ended up going with this guy right here http://www.crutchfield.com/S-6xerGJHvtGQ/p_113KMM100U/Kenwood-KMM-100U.html. I had this setup for a while and it did alright. After about 6 months I decided that the bass seemed to be lacking a bit so I started looking for subs.

Decided on going for the minimalist approach to save cargo space and bought this self powered Kenwood sub https://www.amazon.com/gp/product/B00BO8O9XQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1. I installed this sub under the passenger seat after removing the storage bin (which I had no idea existed until I was looking for places to mount this sub!!!). For the power line I was lazy and just used a micro-fuse tap on the rear auxiliary power socket from the inside fuse box. Grounded the amp on the passenger seat bolt and secured it with industrial strength velcro to the carpet. The handy remote that comes with it just sits on the middle tray for convenient volume adjustment. It isn't the most precise sub and doesn't hit anything lower than 55hz but it definitely rounded out the sound which is what I was looking for.

Now after another few months I want to make it even better. It seems to me that a lot of noise gets in the car, which seems to be the case for many others. Driving on the highway and talking on speaker phone is horrible and I have to turn my music way up. I thought sound deadening would be a great approach to take next. After researching for a while about different products and what's involved with sound deadening I came up with some ideas. First, I am not going to go crazy and do the whole vehicle, that is a lot of money and time which may not be necessary. I am just going to start with working on the front doors and the trunk wheel well if there is extra material. Secondly, I needed to decide on what products to get. This is what I landed on.

Reckhorn ABX http://www.amazon.com/Reckhorn-Self-adhesive-Deadener-Aluminium-Damping/dp/B005JRZPMM/ref=sr_1_1?ie=UTF8&qid=1432694104&sr=8-1&keywords=sound+deadening: This will be for vibration control
Neoprene foamhttp://www.amazon.com/Sponge-Neoprene-Thick-54-Wide/dp/B003IDDV70/ref=sr_1_1?ie=UTF8&qid=1432693500&sr=8-1&keywords=closed+cell+foam: This is closed-cell foam, which won't absorb moisture or odor, and it will help prevent sound from coming in. This is going to be applied on top of the Reckhorn ABX, with 3M super adhesive, within the door frame. I'm hoping it won't come in contact with the window, but I'm not worried since it is only 1/4" thick.

Any extra of the Reckhorn ABX will be applied to the wheel well in the trunk.
What do you all think of that plan and the materials selected?

I also have an MTX thunder240 2 channel amp 80rms/channel @4 ohms that I got for $10 off craigslist(still need to test to ensure functionality) which I want to use on my front speakers. Unfortunately my head unit doesn't have RCA hookups for it (just a sub) so I have to buy a new head unit as well. This probably won't happen for a while because I want a decent head unit with bluetooth and HD radio.

So that's my setup. Let me know what you think about my sound deadening plan.

Whenever I get enough money to do the project I'll post some pictures!

Whether you buy from Don or not, I feel the best noise control methods are the ones described in detail at Sound Deadener Showdown. I have used the products Don sells and they are top notch, so I would also recommend purchasing from SDS if you want to. In any case, IMO, these are the best methods for noise abatement.

There is definitely a lot of great information there. Looks like I have 2 of the 4 components required to extinguish sound. Thanks for the link!

Since I'm not looking for a professional job I'm gonna forth go sound deadener showdown (SDS) and purchase some similar materials for ideally a cheaper price. Obviously this means it won't be as good as SDS, but maybe I'm being presumptuous. So here is the list of materials I'll use for my doors and trunk.

My vibration control which will be applied directly to the inner and outer door metal. I'll only need to apply it in patches with at least 25% coverage, according to SDS.

Decoupler: This should prevent the mass loaded vinyl(MLV) from creating more vibrations. It is a 1/4" thick neoprene which is a little thicker than necessary, but it should fit fine and I will get it for a decent price. It has all the same qualities as sound deadener showdown except it's not vinyl so attaching it to the MLV may be an issue. I'm going to use 3m-77 to stick it and hope that works.

MLV: Decided to try a version home depot sells. Other reviews indicate people have used this for car sound deadening with success. This will be the last layer on top of the decoupler, within the inner door skin.

Finally, I'll put this inside the plastic door panel. It is 2" thick which should fit when squished together between it and the outer metal door frame. It is not hydrophobic however it dries quickly, is microbial resistant, and is fire retardant.

Any extra material I'm going to put into the trunk wheel well since it is easily accessible. If I have much material left, which shouldn't be the case, then I may invest time in ripping the interior out to do the floor. However, that will require more money which may not be necessary for my purposes.

In total it will cost me $184, including some other non-listed items like a roller, adhesive, and mechanics gloves to protect the hands. I'm saving up some money but it's tight right now since I just graduated from college and expenses are flying at me left and right. So I'll keep you guys updated.

Again, let me know what you think so I can make this project the best it can be!
