Is it putting out 1800 probably not but it did blow out one of my 800watt maxx 450 rms subs out with the gain set low so it does have some power.

Many who consider themselves experts need to realize that the power supply in the vehicle may be inadequate. The CEA endorsed formula for RMS rating is: 14.4V x amps x amp efficiency % = RMS watts
To blast an amplifier without putting it on a test bench with a REAL power supply is just plain not fair. Clamp testing in a vehicle will tell you what YOU are really getting but not necessarily what the amp is truly capable of. You don't have 14.4 volts in the vehicle to start with, yet EVERY manufacturer uses 14.4 to calculate their RMS ratings. Next you have to consider the output of your alternator AT IDLE. If you don't load it down with an old-fashioned roll out load tester like a VAT40, you'll never know how many AMPS your alternator can really put out. These little handheld testers they use now cannot tell you that. The number of AMPS available is critical to amplifier output.
