Luke is 100% correct. Sony is still fully in 12 volt (like it or not).
Dow Electronics on Adamo is the local wholesale distribution warehouse for the indie shops and they are fully stocked (rep just came by the shop two weeks ago with this years model spec sheets and brochures).
Their speakers do suck IMO and I really don't have a market for the amps. The HU's are okay as far as style, price, and features-but one of my installers had allot of return failures on them when he was slinging them in at Circuit City for 4 years. I prefer JVC for the price due to a lower defective rate and customers seem to like the style better overall (at my store anyway).
Panasonic on the other hand, out of 12 volt for 2009! I understand from another rep that Clarion is on the fence also for 2010 on the 12 volt. Clarion is more of a rumor though...
