Kenwood X502-1 Class D Monoblock Power Amplifier X5021 (Renewed)

Nice little amp

I did not get a bass knob with my amp

This was a new refurb unit and played 1 note and quit. I have installed audio for over 25 years and this was disappointing. I did not install immediately and was told it was not under warranty.

I bought a "refurb" and the only issue I could find was a stripped screw... I bought a slightly larger screw and the amp has worked perfectly. Matched with a kenwood sub and couldn't be more pleased.

But really a NO!!! I had it professionally installed bass knob and all. It performs weak no matter what the shop tried. It was renewed but obviously NOT correctly. My return was approved by Amazon but the seller would not take it back because it had been installed??? Shady outfit I’m stuck with a paper weight in my closet now. I think it might work for one 8 inch sub rated at 150-200 watts. Maybe then it will sound okay and not go into protection mode? 🤬

I believe this refurbished item needs more refurbishment. No power I've got a 350 w rms @2 sound ordnance that makes it look horrible. Same set up speaker ,head unit ,ect. .. just put it in yesterday gonna take it back out and return it . Hopefully that works fine.

Good product should be able to push A 2ohm sub. I had a JL audio 10 inch 4ohm and was not that happy with power at 4 ohm. 2 ohms is 200 Rms high than 4.
