They also sell several brands of mobile security systems and a huge range of wiring and accessories. They also do professional-grade home theater with installation and it's a fella that I've known since we were 5 yrs old that does those installs.
The manager, a fella named Tony, is an absolutely great guy to deal with. He's not one of those kinda salemen that will try to get you to buy a ton of gear that you don't really need. When I first got introduced to Diamond Audio as a result of being in his establishment he wanted to sell me a DAT M6mkII 12" and I was a bit dubious about buying one at retail price. He explained to me about DAT's warranty and then let me have an M6 over the weekend to 'audition' in my car (where as we all know it won't sound the same as it did in the place that sold it to you) to make up my mind before dedicating myself to the purchase.
The installers are personable and professional and make it a point to make their appointments on time barring any extraordinary occurrences in any one install.
The prices aren't out of line with what you'd expect to pay retail and their installation fees (if you choose to have them do it rather than do it yourself) are more than reasonable.
Hard to beat the attitude and the service you'll receive here. Highly recommended!
