Yes I have but I am also in car audio and it is very much personal prefrence the brands I like suit my musical taste and are a little bit of a different breed in comparison to your products (example the Oz 3-way setup I just purchased to put in is a high end SQ set that retails for about a grand a set comes with tweet 4" mid and 6.5"mid/bass...other setups in different vehicles use BRAX, Morel, Blaupunkt Velocity and some others) I would love to use factory wiring to get the Arc amps I am planning on paring with these components running it would be stellar! plus that way I can amplifiy a proper three way component system keeping the excellent sonic placement of the dash mounted mid to keep the fron stage more on the dash instead of in the footwell if you have the plug and play hookups for this on the amp and on the speaker end I would be more than happy to purchase them along with the line output converters...
