My Subwoofer configuration.

[Matt]

I have 2 MM120's wired in paralell to a rockford fosgate 500bd amp. How much gain and power can i deliver to these subs? Also, what is the surrounding on the sub? How much juice should i be givin these subs?

Matt,
The Rockford Fosgate 501bd has a power rating of 500 Watts
into a 2 Ohm load. I would recommend setting the gain on the amplifier to the 1 o'clock position and use very little or almost none of the "Punch Bass" EQ. This will help to prevent clipping the amplifier and reduce the chance of distortion when listening at high volume levels. The end result will be a clener, tighter bass response. We use rubber surrounds on the MM120's. Are you installing these subs into a sealed or bandpass enclosure?
