How do you match the amplifier to the sub? I have a 12" Rockford Fosgate Power Series 4 ohm and need a amp for it. It is 600 Wrms and 1200 Wpeak.

 

Is your sub a dual voice coil or single?

 

you want to over power the sub some what for it doesnt have to work as hard.

 

agreed plus you it will be more clear if you dont have the gain turned all the way up Check out the Kenwood 9102

 

very true. i have a 400RMs 800 max sub with a 1500 watt amp, bridged at 900 watts at 4 ohms only turned half way up.

 

If your sub is SVC I'd recommend somewhere between a 600x2 and 800x2 RMS amp. If it's DVC I'd recommend a mono 600-800 watt RMS amp. You can definitely go bigger if you have the budget for it, the bigger you go, the less you drive the amp and the clearer sound you will get, as the other guys said above. Definitely don't under-power it though, contrary to popular belief it's easier to blow a sub by under-powering it than over-powering it.

I have 2 500watt RMS subs pushed by a 1600 RMS amp, gain is set low and it will last forever....
