I鈥檓 using it to power a pair of 10鈥 8ohm 50w Dean Markley guitar amp speakers in a homemade cabinet to use with my Positive Grid Spark Go 5w practice amp. I run an 1/8鈥 stereo out from the aux/headphone Jack to the stereo rca input. Powered by a small 12v power adapter it puts out some decent sound for the studio and small venues. Still need to mount the amp, wrap and put the grill on the cabinet but so far I鈥檓 thrilled with the results. Beats spending upwards of $300 on a brand name cabinet. Total investment including speakers, tolex, grill cloth, amp, power adapter and wood was less than $125
