I've known Larry and his technicians for a couple years. Originally, Larry and David put together a custom top-notch audio and Alpine radio install in my Honda coupe. I've enjoyed my system tremendously. Additionally, when my high-end speakers started to physically warp, Larry helped me out by replacing them AFTER my warranty had expired at no charge. Larry has also installed Sirius satellite radio in my two other cars.
My latest install by Perzan is a Pioneer AVIC-D3 in-dash navigation unit with Sirius, iPod, and Bluetooth. This unit is amazing. Larry went above and beyond to activate my Sirius radio on my account for me, saving me a half an hour on the phone. He helped me to sync my BlackBerry along with its address book into the Bluetooth unit so that I can dial my contacts with a touch of the navigation screen. The installed unit, Bluetooth microphone, and navigation antenna have a factory look. I couldn't be happier.
There is nowhere else you should go for your car audio needs. Perzan's work is pristine, their pricing is fair, and most importantly, they support their products. I've had poor experiences with using cheaper shops and chain stores in the past. Perzan's shop is equipped with fabrication equipment to make any custom install perfect, and Larry is a master at sourcing foreign parts to put together installations not possible by other shops. If you care about your car and want the installation to be right, look nowhere else.
