In my life have owned many systems from jl, fosgate, to as cheap as Sony. When I left for the military I sold all my sound equipment therefor when I returned home I had no boom in the trunk. I started to look around on many different site but I found nothing that stuck out at me till I came across this bundle. I have owned mtx in the past and had great results from them so I decided to go with and I am pleased to say it is hands down the bet deal on the web!! Sounds great, looks nice, and is compleate in the package to be able to plug and go. For the money this can't be beat I promise you that! Also I want to give major kudos to sonicelectronix for fast accurate shipping, and excelent customer care. You have earned a lifetime customer and I WILL be back to buy from y'all!! THANKs GET THIS PACKAGE!

After shopping around for the exact speakers I wanted for my son's truck, I found them to be the lowest price at Sonic Electronix. With the fast shipping and great service, I am sure to be a return customer.
