The Clarion M109 deck that I bought from Sonic is a great deck and a great buy! It is primarily designed for a marine environment and so has extra protection for the circuitry. I work in construction so even though there's no salt air I don't think so that extra protection can hurt.

I wanted a Clarion, because our trucks at work are prewired for Clarion, and I wanted the deck to be plug-and-play. This one was and it's an awesome deck, at an awesome price!

But what I really liked about this deal, was how slick it is to order from Sonic and have it shipped to Canada, with the duty, brokerage fees, all included in the final price. The overall ordering procedure for Canada was as good as it gets [PayPal availability also great] and because of that I've been back to order since.

I'm a very happy customer!!
