Although I haven't worked with the equipment you mentioned, yes I believe everything will mesh together just fine.

Ohms. Before I can simplify it for you, I need to complicate it first. In DC (which is Direct Current) Ohms is a measurement of resistance. In AC (alternating current) Ohms is a measurement of impedance. The difference between the two, is that impedance incorporates frequency. As frequency changes, the impedance will change. Confused yet? Sound is alternating and is different based upon its frequency. Don't worry about any of this.

What you need to worry about is parallel or series. When you wire the speakers in series (the wires go to the first speaker, then from the first to the second speaker) you add the Ohms together. So you have two 4 Ohm speakers. If they were in series, 4+4=8 Ohms.

When you wire them in parallel (the wires go to both speakers at the same time, you'll see this referred to as bridged) you divide the Ohms by the amount of speakers you have, 4/2=2 Ohms. (This would be so much easier with pictures.)

To be able to get the amount of power you are supposed to get from the amp, the impedance of the speakers need to match the impedance of the amp. The B54 amp has 4 channels. So you will only have 1 speaker on each channel, you don't need to worry about series or parallel. Just make sure the number of Ohms of the speaker is the same as what the Amp is calling for. I believe from another post, it was confirmed to me that hooking up only 2 speakers (rather than all 4) will not cause any problems; you can add the other 2 later.

 

Running the speakers in parallel will get you more “power” but only if your amp is stable at two ohms otherwise you will run more current through it than it was designed to handle. The formula for running speakers of different impedance in parallel is a bit more complicated...but it should not be an issue here. Just ensure all the speakers are 4ohm and the amp is 2ohm stable, then you should be good.

I did the same on mine...replaced the 2 front speakers and added an amp. I have speakers and pods to go into the lowers later this year. My amp will handle a 2 ohm load so I am all set there.

 

"150W X 4 @ 2Ω, 80W X 4 @ 4Ω RMS Power"

So the above came off the CV website in the details for the B54, so does this mean it will handle a "2 ohm load"?

 

Yes it will.

As cantrider explained, you’re fine from a math perspective. You won’t need to do any series or parallel wiring because each speaker will have its own channel regardless of whether you start with 2 or 4 speakers. With that amp you can use 2 ohm or 4 ohm speakers as long as each is on its own channel. I’m not saying to mix and match, just that the amp is stable at both ohm ratings.

Power (watts) equates to volume going down the road. Keep your expectations in check, that amp only delivers 80W with 4 ohm speakers so it’s not going to get super loud.

What people tend to forget about on budget level components is how well they work together. Certain speakers sound good with certain amps and vice versa, others don’t and there’s no way to know unless you know someone with that exact setup and can hear it for yourself. That part of it has nothing to do with the math, it’s about the physical construction of the amp and speakers, your ability to tweak the amp to match the speaker, and of course your personal ear for music. That’s why so many guys change entry level components like underwear and many of us say buy once cry once. I’ve never heard that combo and don’t know how well they work together, just throwing it out there so your expectations are reasonable. The same applies to high end components, but to a lesser degree because better equipment can make up for weaknesses.

OK, that makes sense

Understood, I just don't have bundles of cash to drop on this.

So would 2 ohm speakers be louder of softer?

 

wow was i wrong!!! i thought "ohm" was something the DALLIE LAMA says when hes stoned ohm-ohm

 

Here are some pictures to help you understand the words above...

 

Also remember to wire the "+" jack from the amp to the "+" terminal on the speaker. Usually, the wires are coded so you can keep them straight. Speaker terminals are coded "+" and "-", make sure you wire them to the "+" and "-" on the amp. Usually, the "+" terminal is Red and the "-" is Black.

 

Or they will color code to keep the pairs together left pair is one color, right pair is another color, etc..


In that case the striped wire is ground.

 

I'm running the Kappas in my fairing and the lowers and a CV B54 amp pushing all four speakers and sounds really good. When it comes to the amount base for me it just depends on the song...
