Summary: The factory refurbished 200 2.2 amp was as new and tested to be 224 RMS. A great buy. It has filters to deliver clean signal from oem radio speaker wires. You can then use the Kicker's rca outputs to be both the input/activate signals for the sub amp; giving it the same filtered signal.
Summary: This is by far the most powerful 200 watt amp I have owned. It is currently running my 6.5in kicker components in stereo as well as an infinity sub in a mono bridged setup. That is a lot to ask from an amp rated for only 200 watts. This amp will do it without clipping or overheating.
Summary: I bought the amp purely based on Kickers reputation as a leader in the car audio industry. What I received was way more than I expected. I installed the amp in my dad's truck as a Christmas gift, and he loves it.
