OEM-1 makes it easy to upgrade a factory 'premium' system, such as a GM Delco/ BoseŽ or a Ford/ JBL. Whether replacing the factory radio or amplifier, the OEM-1 is your 'plug and play' solution.
I had been researching products for my car stereo system, and finally came upon this site. I thought that the price of the subwoofer that I was looking for was to good to be true. But I went ahead and placed my order. The package was shipped fast, and it was in perfect condition when I received it.
