Ok I have now bought a Sony HD stereo and a Biketronics kit to install it with so the auto volume will still work (even though I think the Hawg Wired install looks better and will wind up getting the mounting hardware from them). What brand and depth 6.5" speakers with adapter plates for the front and 5.25" speakers on the rear are recommended? This is for a 2000 Ultra if it makes any difference on mounting depth.
