You can't beat the sound for this price--guaranteed. Anthony (I believe was his name) and Joe Rodriquez helped me with EVERY aspect of sound, explained every detail so that I could understand what would work BEST for my car's set up and audio limitations. I had a perfect experience other than it took a little longer than promised to install, but they gave me a discount for that since I was late to work because of it--very understanding and down to earth people. I paired TWO of these 10" Kicker subwoofers with just one Kicker 300i Amplifier, which isn't ideal but it works for now, and I plan to go back to Joe with questions about how to upgrade in the future. It sounds better than I could have ever imagined for the price that I paid.Truly thankful, these two, especially Joe, deserved a huge tip or bonus but I was cashless. Next time that I am in, I promise to bring something worth both tips my friends! Thank you again.
