no clue on the model numbers but believe me, he cant be overpowering the 2000 watt max subs with a 700 watt max amp.. and its all at the same ohms, the installer checked it and so did my friends dad...
just thought i would say, we never had any of the levels over half on the gain, bass boost, etc..
Edit: im a complete Newbie to car audio so all i know is what my friend told me
now i bet i could wire up multiple tvs with a live editing studio in a car
