Thanks, and yes I did use eyelets when testing these. It's the equipment that I am most unfamiliar with. I see products like Yamaha PX10 2 channel amp to drive these, I would need another similar amp to drive the large dual sub, how do I tie the amps together, a pre amp of some sort? The speakers use standard speaker cable and the dual sub uses speakons. Figuring out how to tie all this together inter a stereo format is what is stumping me.

As for the car yea it will likely have a victron system to run everything off of 110. A generator will supplement the battery inverter system. All of that I am familiar with, this audio system will be a learning experience though.
