Good knob at an awesome price.
Had a few other brands of amps before switching over to SQ, and I always had to buy the remote knob, cause the previous owners never keep them. Same deal with my 4500, but I was very pleasantly surprised to see a 15 dollar price tag, vs the 40 dollars that some of the other brands charge... for what appears to be an identical item.
Anyways, This thing came quickly, and works exactly as advertised on my SQ4500 amp. Also, the green LED on the unit is quite a bit more comfortable for night time driving, vs the blue that other knobs use (which I always had to tape over).
