Did I make a mistake buying this amp? (CER-B4)
So in my haste on ebay I bought what I thought was a Cerwin Vega B54 amp. Turns out it's actually a CER-B4 amp, 2014 model. I have both manuals and they are the same size with mostly the same specs as far as output goes. Main differences are in some crossover settings.
Anyone have any experience with the B4 amp? See attached pics of specs, connections and settings.
Bought to maybe replace the RF-PBR300X4 amp I'm working with at the moment. I say maybe because that amp is all wired in and functioning OK. And as an add I tweaked on it yesterday and with that and the settings in the Kenwood amp I was able to get the Biketronics Titan 4" speakers to outright scream without distortion. The critical setting for that was putting the HPF on HU at 100hz. The RF amp on All Pass, I believe is 70hz and not adjustable.
Been a crap week with some family medical issues, and with work I haven't had time to finish getting the rear pods in. How everything sounds when I finally get those in will determine if I swap amps or not before I button up the fairing.
I haven't received the CV amp yet, but have discussed the typo issue with the seller and he was cool and accommodating. Saying if I didn't want to keep it I could return it for a refund. I probably won't tho. For $100 I am thinking it was still a good purchase. Since I can only put 4" speakers in my older vintage fairing, and 6'5" in the pods. I can only push em so much anyways.
Mainly just curious on the differences in the B4 vs the B54 amps.
Thoughts and Opinions?

That being said the RF is indeed 75x4. But the B4 is only 80x4. So in that regard what is the big difference.
As a note on previous comments, I do not need to bridge or run 2ohm. So in my case is there really much of a difference? Spoke too soon. See below.
