So I took some time on the Thanksgiving day weekend to work on the audio in the S. After going to the local Tweeter store thats going out of business all I had a choice of picking up there were some JL Audio wiring kits and a bunch of Dynamat. Got the 4awg wiring kit for 30 bucks , original price was at like 195 and picked up the Dynamat trunk and door kits both for 70. Then went on to the Home Depot and bought some MDF for the box. On the way home , stopped by a hobby lobby store and bought a yard of leather/polyester for the box as well. Seeing as how I already had the amp and speakers , my buddy gave me his sub that he wasn't using and I went ahead and installed that. ( Excuse the mess , it started to rain and I had to bring everything in really quick ) I got the sub woofer box design from something I saw on ebay but would rather build myself. Its leather wrapped and I added like a staircase on it to mount the amplifier. The sound is amazing from both the speakers and the sub. Volume can be raised all the way and the sound is crisp and clear.

Man that amp is huge!

 

Ya , its pretty massive . Couldn't think of any other place to mount it. Gives 125 rms per channel tho , so its worth it.

 

HOLY COW!!.. I would never want to loose that much trunk space

little bit of excess power cable? hehe.

how often will you use all that 125W though?

I drove a set of infinity perfect 6.1 compents with 45W with JL amp and i was going deaf.

 

is it good to put the amp over the subwoofer?

I was told that the vibrations may damage the circuitry
