X2.. I personally wont run ANY amp on a weak electrical lol.. But if you do beef up your electrical that AQ is nice //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.. the old 3500 was rated 3500@ 1 but the new 3500D.1 is a bit more powerful. IMO its hard to beat AQ's quality/power for the price, being brand new from the manufacturer and warrantied..They are awesome amps.yeah, i wouldnt want to run a stetsom on a weak electrical...
