Either will work. Bridging the b54 as gann stated will give you a lot more room without potentially clipping the amp. If you contact LL247 here you could get the diamond audio micro 4v2 ( same basic amp as b54 with better build QC) and be very surprised on what the cost will be.

 

would bridging my amp help??? it would drop the motos down to 2 ohms...would that wake up these motos...my amp's birth certificate claims it rated at 389 watts...

 

Your amp can't run 2 ohm bridged. In 2 ohm stereo still same power as 4 ohm bridged. No getting around it. You need more power.

 

forgot to tell u that I have an aquatic av stereo in the bike....would that allow me to bridge the speakers and amp....

 

No. Source unit is irrelevant. No matter what scenario involving the pbr300 and the arc motos will work. You will never have enough power with that amp and those speakers. Sorry.

 

ok...I guess I will have to buy a Cerwin Vega...b54 or 52???

 

Also, bridging a 2 channel amp only allows you to run 1 speaker not the pair. True you could bridge and run the pair of speakers (theoretically) but why would you...you'd basically be right back where you started. To bridge you need a 4ch amp to run 1pr of speakers.

 

The Cerwin Vega amps are getting hard to find. I think they are getting phased out for the Diamond amps. However there are still vendors that have em in stock but they are going fast!! You want the B54 or the B52.

 

Update: I spoke directly with RF this afternoon and of coarse the rep told me "You will have no problem driving those speakers with that amp." He was convinced that the 300x2 would drive one set of 602 motos with no problem even though they are 4 ohm speakers....IDK I guess that is why I am here to find out from you fellas....

Again I am asking which CV amp would be recommended the 52 or 54?

 

If you think you may wanna run it in bridge mode OR add speakers later go with the B54.
