About The Designer
In High School I made the Who’s Who Among American High School Students for Electronics. Later I became DC-1A Theory certified in Electronics while working as an Electrician on Navy Ships. I have read car audio books, speaker building and design books and know the math formulas for determining capacitor and coil values for any frequency I choose. I have been in the custom stereo business since 1989 and know how to tune a box from 35-80 Hz for a 12 decibel boost in bass, and sound damping for a few more. My Integra has ten Tweeters, eight Mids, four 6.5 midbasses, two 10″ subs for bass, and three 12’s for subbass. I aim for loud, clean, and bright sound that will get heads turning.
