An amplifier wiring kit that gets the job done

The following review is for SK4681, which is a part of the bundle you are viewing.

Had everything I needed, including 2 larger sized (8ga - 12ga) butt connectors, which I ended up using.

I should noted that I did end up buying a separate Stinger 4-Channel RCA cable as well. I didn't require speaker wire as I was able to re-use my cars wiring.

Excellent product

The following review is for CDM, which is a part of the bundle you are viewing.

This is great material and is very easy to put on with a heat gun!

Great package deal value.

The following review is for CDM, which is a part of the bundle you are viewing.

I recieved this as part of a package deal. It is enough to cover the lid of my 98 Civic sedan trunk. This will clean up the sound of your lows by decreasing noise (rattles, distortion of sound, etc). This is the first step in noise reduction and everybody should start here.

I doubt it will create a noticable increase in sound from your speakers.

Very flexible, sticks like crazy! Easy to work with.

Great Price and Product

The following review is for CDM, which is a part of the bundle you are viewing.

I found the price great for the product I got. Installation was very easy, product sticks very well (Remember to clean/prep the surface). I noticed a difference right away in my music as well as overall noise level while driving on the highway (Doors done - trunk is next). Not the thickest sound dampening out there but it def. helps :)
