never had a SQ so i couldnt say on that.no i wont be selling it.im going to keep it for back up. just go on
ebay and get one for around 150 shipped if you dont get the sq.damping factor on the rub 1000 is 250 and 105 signal to ratio.it makes my d6 sing and sound good doing it.the ss rubs are overlooked a lot of the times but i have no complaints.just because it isnt a $500 amp doesnt mean it isnt any good lol..it is a little bit of a current hog though.had to put a big agm under the hood but i also have an under drive light weight crank pulley
