Azzazel_99 Posted February 22, 2013 Report Share Posted February 22, 2013 probably gonna get flammed for this but im using the polk dxi 660A mainly only because when i got it i got 70% off their list pricing but so far im happy with it. Got it running 4 dxi 6500 bridged pushing 85 watts rms i believe and it sounds amazing. Link to comment Share on other sites More sharing options...
FeelDaBass Posted February 22, 2013 Report Share Posted February 22, 2013 If they are 3 ohm speakers...then I would NOT get the RF pbr 300x4 as that is only meant for 4 ohm loads. You can look at the average of 2 and 4 ohms on an amp and figure about thats how much your speakers would be seeing. Such as, the Rockford Fosgate p400x4 is rated at 50 watts rms x4 @ 4 ohms & 100 watts rms x4 @ 2 ohms. So if you were to use this amp, you can supply about 75 watts rms to 4 of these speakers. (Which is about what I would recommend, as long as you don't bring it into clipping) even though the PBR says 4ohm, it will run a 3ohm load speaker, I have it runinng on my wife with a 3ohm load, please dont talk if you dont know what your talking about. Is that because of impedance rise or just an awesome amp? My apologizes, have never owned that amp but assumed that it wouldn't be able to handle that. It looks like it would be pretty inefficient for the electrical though. Its average efficiency @ 4 ohms is 55%. Pricing is a little lower as it is on sale right now for $111 shipped on eBay right now too (the R300x4).

FeelDaBass Posted February 22, 2013 Report Share Posted February 22, 2013 Granted the amp is a little larger. Probably about twice as large.

naughtyca Posted February 22, 2013 Report Share Posted February 22, 2013 the PBR is one of the smallest footprint amp Link to comment Share on other sites More sharing options...
FeelDaBass Posted February 22, 2013 Report Share Posted February 22, 2013 If I had a small space to work with, then I'd give it a try as he^ knows more about that amp than I do.

Kranny Posted February 22, 2013 Report Share Posted February 22, 2013 probably just impedance rise making the pbr amp see more than 4 ohms. otherwise it would (hopefully) go into protect. Link to comment Share on other sites More sharing options...
