Here's a little video I did of converting a Kemper unpowered rack to a Kemper powered rack... if you do this you might well lose your warranty...
BTW its all on the video so please don't harass me with questions on here. If you want to do that then put them on the video on my channel...
Please note I did say the amp was a 290w unit which is incorrect... it is actually 2 x 90w in stereo or 180w bridged..
thanks
I Hope it helps someone but please note that the video remains my copyright...
Thanks.
