After reading prior great customer reviews here, I decided to try Autobahn. I am a musician and a gadget guy, and want great sound and professional installation. Frank, who turned out to be a former percussion student, did the XM radio installation. It was wired so that no external wires are visible and he also re-wired my GPS to hide all wiring. I had the same installation done later the same day on my Jaguar and it also was perfect. In addition I had HID headlights installed on my Town Car. At first I tried new more intense bulbs, but wasn't impressed with the light output. Reza, the boss, gave me no hassle and full credit when I swapped the new bulbs for the HID Xenon lights the following day. Dominic did the light installation and I am extremely satisfied. I say "go for it" at Autobahn when looking to upgrade sound and lighting for your car.
