Depending on the model of RF 10 depends on both of your questions... For information on the fosgate subs go to www.rockfordfosgate.com

or basic break down is...

RFD2210- rms 500 watts, sealed min..375 max. 1.75 ------- ported 1.0

RFP3210 Rms 400 watts, sealed min. .375 max 1.75 ------- ported 1.0

RFP3810 rms 200 watts, sealed min. .625 max 1.5 --------- ported 1.0

RFP3110 Rms 1000 watts, sealed recommended .65 ------- ported 1.75

FRZ2410 rms 100 watts. no data on box size

FRZ2810 RMS 100 watts, No data on box size

RFZ3410 Rms 150 watts, sealed .75 -------ported 1.0

RFZ3810 Rms 150 watts, Sealed .75 -------Ported 1.0

In reality you cant have to many watts. normally speakers are blown because you dont have enough. when you dont have enough and you try to go loud you clip the amp causing severe distortion and that frys the coils. you can run gobs of power as long as its clean ( key word here ). I once had 2 polk audio 12s that had an rms of like 125 ors somthing really low like that i was hitting them with 500 watts rms apiece ( now there in my bed room ). now I have 2 audiobahn aluma 12s getting about 800 each sounds pretty good but I wish I had 3 image dynamics 10s that sounds so clean and load.

That VisionOrb dude is righton. If you don't have enough cash to get a big, good amp then look at the numbers that Prembird posted. I'd try to get an amp with AT LEAST 75% of the RMS power that a sub is rated at for maximum RMS power handling.

Do you know anything about the Rockford RFZ1810. It is not listed on there website. My buddy has a few of these laying around that I want to use. Thanks

Some good accurate info in this thread....

One more point to consider because it's another one of my "pet peeves" about stereo manufacturers:

Be sure to understand HOW they are rating the power of their amp! There are a lot of tricks they use to make a junk amp SEEM like it's powerful....like using PEAK power instead of RMS ratings...or spec'ing power at ONE frequency instead of the full 20-20,000Hz range.....or not specifying the ohm rating, or distortion level at their "rated" power output.

This is one of those times when buying a reputable "brand name" amp can be worthwhile.


1000 Watt amps for $100 don't exist....



Sounds like you are already asking the right questions though...! /forums/images/graemlins/thumb.gif

Good luck.
