has anyone heard of peripheral interfaces.

im having a hard time finding the swi pac ver 1.6.8 locally but have come across a similar unit made by peripheral

has anyone know anything about this company

if so do there units suppport voice controll.

The two companies appear to be affiliated but go with PAC to be sure. You should easily be able to find them. Google PAC SWI-PS and you will see several merchants that sell them. Once you decide who to order from, call them to make sure they are selling the 1.6.8 version.

They are the same company. They sell a number of brands of kits, harnesses, cable, sound deadening, install accessories, etc under different brand names
