Basically, you just described my system
. Nothing fancy, bridged into one channel, and cheap
.
I couldn't find anything online for KW Surplus, and since I don't have a kitchener phone book - I'm useless to you. I do know they are a cheap operation - really dumpy, but they have good prices - that's all I cared about
.
Other than that - I really am kinda dumb when it comes to car audio. I had my brother install the system into the Cougar when I first got it, and then I basically duplicated the process onto the Marquis when it was time to switch.
Check out that CarAudioForums - some pretty bright people there, and some good articles.
Have fun
