I recently bought two Infinity Kappa Perfect 10.1's from a guy on craigslist. The guy told me they were practically brand new but I want to test them out to make sure. How can I test them out? I have a box for them.

 

ummmm hook them up and see if they work?

 

i test my kappa perfect with my Audio Video Receiver in the house. Since my receive outputs high and mid too, I just turn the volume really low, and feel if the sub is moving. I don't want to blow my sub.
The best way to test them is to connect to someone's car system.
But all my friends runs on stock.
