I am upgrading my power on this sub from a Viper 1200, which already got it loud as piss, to a US Amps 07 model Merlin MD3D for daily street beating. How will the sub take the power? I have heard that in this power range in when the sub will really come to life. This won't be too much for daily will it? And what kind of increase in output can I expect? I know it may seem like a dumb question but any respones are welcome.

in my personal experience a Usamps I/S 4085 (4 channel) outperformed my viper 1200D like night and day during sub duty. it will get MUCH louder and sound a heckuvalot cleaner

Love the user name, but I have not played with that sub yet to know for sure.

It will shine with that kind of wattage, just be careful with the gains

What kind of power does that amp do? I'm running 2 HD's off of 2 1500D's strapped at 1.5ohms. It's more than enough for daily and quite musical with the gain turned down a little. Gotta love that remote gain knob...
