Is this digital or mosfet?

Yes if I know what their problem is and if not I'll let them know to reach out to stereo shop or a friend whose more knowledged as an Electrical engineer and stereo professional at competition level.

What gauge wiring will I need to connect this amp to my truck?

I would use at least 8gauge. Prefer 4 gauge

Thanks for your question. Power (watts/ch) 4 Ohm Stereo: 65 x 4 Power (watts/ch) 2 Ohm Stereo: 90 x 4 Power (watts/ch) 4 Ohm Mono: 180 x 2 World Wide Stereo – since 1979 – and a proud authorized Kicker dealer.

Will this amp work with 2 kicker cs 6x9 and 2 4x6 kicker ks?

This amp all work but its best to go with more powerful amp so you can keep the power gain down and still have power and the amp will never get hot as in 1 turned up for power with heat up. Kicker is the best amps on the market right now for reliability and true power!
