Well hello all! Just thought id chime in and say hello, im a relative n00b to all you people lol And im definately not loud I'm using a single BTL 18 and only doing a 155.3 in Prostock 601-1800, but wait till i get my other two amps hehehehehe As for 4kw's i sold one for $650 shipped a week ago Now im running a pair of Sundown SAZ-1500d's which are uy far the most solid amps ive ever run - just as a comparison i burped my 4kw @ .5 ohm and my pair of 1500's at .5 strapped (.25 per amp) and my 1500's are almost a full db louder than the 4kw O yea and I did a 153.0 in Streetbeat with the pair of 1500's strapped at 2 ohms (how i run them daily)
