I install products for mobile audio about 1/3 of my time spent at work as an ASE certified auto tech. I've used Zapco Z series, JL Audio, Hybrid Audio, Focal, American Bass, Orion (old & new), Rockford fosgate (punch to power), Crossfire Audio, DB Drive Euphoria, and a million other brands. I use Audio Dynamics as much as possible now. I'm sorry, but it's true.... Buy a set and listen. I put a set of 4000 series 6.5" components on a Zapco Z series SP amp and we did back to back with another very similar sedan running legatia 8 inch components on a Rockford power series. Out of the 5 of us there 4 of us thought the AD setup sounded better. And it was damn near as loud. Guess what vehicle the person owned who didn't side with the rest of us?
I've installed about 8 sets of AD mid-ranges so far And I'm never disappointed.
I brought a customers car to another very high end shop here to get a sublet quote on fiberglass work as I don't do fiberglass. He heard the 2000 series 12" AD sub in the trunk and immediately asked me "who the fxck are these guys?" It was in a custom box I built to AD spec and it sounds damn good. I've seen allot of people bash the owner of AD. I speak with him fairly regularly. He's never hated on another brand to me on the phone, he's always been informative, punctual with call backs, and very attentive to detail. He wants to make good products. and..... Yes, I think he DOES want to beat up on giants that are caught resting on their name. AD listens to their customers, installers, and current trends.
Ive had some good systems in my time, and I'm impressed with AD, but when I show other installers that have been in this game decades these products, and I see the look on their face, that's how I know I'm on the right track with this company. You can put these speakers in a bowl of water for a half hour playing, take them out, and they still sound good. There's videos on YouTube of 3000 watts getting pushed through a pair of their 600 watt subs hitting crazy dB numbers. And still living on and sounding musical. AD is a solid brand, and deserves a little more respect and attention from the masses. I'm not part of this company and I don't get any incentive for this post. This is just the reality. Take it for what it's worth
