XS power has been around for awhile. Great battery's, lots of choices, best small battery warranty at three years. I used to sell them when I worked at a car audion store...

I bought this one and installed in June of this year. So still have warranty.

Needforwings kit is great. I just like making my own things and saving $. tamamto/tamatoe

Selling because I have decided to start doing stereo competions again and need a huge battery (bigger than stock) for my needs. And it will be XS as well, great tech support and product knowledge..


I forgot to put that this is a xs - D680...

Good luck.
