Just installed a Alpine CDA-9835 headunit in my cobra. I spent a good amount of time researching a good head unit to match the interior color of the gauges and this thing is great. It has a feature, I personalize, which enables you to dial in the specs of the speaker system to get the best sound. Has anyone used this at all? Its asking if the stock Mach system has 2 or 3 way speakers? Who can help out? Thanks in advance.
