Installation was quick and straight forward. Fit is perfect. Sound is phenomenal. Only negative: The seatback will only fold down halfway, but since my amp is in the compartment behind it, I rarely need access to it anyway.
I use a Kenwood head unit with internal 200 watt amp set to highpass @ 150 hz. to feed 4 Kicker door speakers for mids and highs. I use a 200 watt Kicker amp set to lowpass @ 85 hz. to feed the Mtx sub.
