So I was driving down the road today, and I spotted a box with two circles on the top. Curious, as I was looking for a set of subs anyway, I pulled over and picked up the box with an amp on top. It's two 12" Kicker CVR's and a 1500 watt Boss amp. Is there an easy way to tell if they still work without setting up the wiring and all? I'm relatively new to the field of automobile electronics but I know that they are in decent condition. Thank you in advance.
