I have this J&M Rokker XXR 330 unit and it is fantastic.I can speak from experience. Stay away from J&M.
I think that amp is for 4 ohm speakers only, capable of handling 100 watts/ channel , on 2 channels. If you plan to run four, 4 ohm speakers ,you run them in parallel on 2 channels achieving 2 ohm which the amp is capable of.The Kappas I have are 2ohm and when looking at the bt2180 i see where they plug in then there is a place for a set of 4ohm. So cant I power the 2 fairing speakers using the designated spot then run 2 4ohm in the parellel connection for lowers ? Or do I need to run 4 4ohm speakers?
Yup, I read that right after I posted. I was thinking BT2180 and a set of Hertz ECX 165.5 speakersI think that amp is for 4 ohm speakers only, capable of handling 100 watts/ channel , on 2 channels. If you plan to run four, 4 ohm speakers ,you run them in parallel on 2 channels achieving 2 ohm which the amp is capable of.
From my understanding of the literature. I'd call bt to be sure.
I'm really 99% on the 4180.14. Picked up my bike yesterday and ya, I can't hear my shit at speed barely. I will eventually get speakers in my lowers. So I'm going to get to 4 channel now. Expand later. I like the all plug and play.I have not heard much good about the J&M stuff but to be fair I have never actually HEARD it. Supposedly there is a lot better equipment out there for the money. Case in point, Biketronics or Arc Audio (if we are talking amps).
I have the BT4180.14 and love the simplicity of the system (no gains) and the warranty/customer service. You are not going to find a better warranty and resource for questions than Mike and Donna. If money were no object or I could start all over, I'd get the new BT4250 (so new it's not on their website yet). It is a 4 channel version of the 2250 and has some gain control adjustment. Spendy (I think it's $800-900) but, buy once cry once.
When you start getting the audio bug, there is no stopping. I am SO glad that I bought the 4 channel amp to begin with, even though I "just wanted a little upgrade to my fairing speakers". Ha!
Put an $800 J&M in my SG. Didn't sound good for me at all. I ended up putting an RF amp and Kappa speakers and was pleased with that much less expensive system.WHOA, really? DO you mind expanding? Our buddy the law abiding biker recommended the J & M system, not arguing or defending, just explaining why I'm asking.
With those choices, Biketronics. Actually there is no choice, Biketronics.
