QuestionHi. I have a jensen bp212 bandpass speaker box with two 12" subs inside that runs at 2 ohms but is wired in parallel internally (each sub is at 4 ohms but run parallel) and 4 speakers that run at 4 ohms each. I also have a 4 channel amp (jensen powerplus1304) that runs * 4 ohms: 117 watts x 4 chan.
* 2 ohms: 145 watts x 4 chan.
* Bridged, 4 ohms: 290 watts x 2 chan.
I want to get the most power out of my amp by hopefully bridging the bandpass box at 4 ohms to get the 290 watts. But there are two 4 ohm speakers inside that are wired in parallel to get 2 ohms. Is there any way i can wire them to 4 ohms for bridging?
And what is the best way to wire my four speakers to get them at 2 ohms for the maximum rms??
i want all of this to go into the 4 channel amp, using 2 channels for the speakers and the other 2 channels for the sub woofers.
..im rlly confused about all of this!
AnswerHi Josh,
I'd strongly suggest getting another amp to run all that, since you can't (reasonably) run 4 4ohm speakers on 2 channels unless you want to really lower the power, or run two speakers off of 1 channel bridged (even the non-subs).
If you choose to do that, all you can really do is:
Wire two speakers in parallel to 2 of the channels, giving you 2ohm circuits across two speakers, and then run the two subwoofers in series (keep the double coils in parallel) giving you 2x4 ohms across those circuits.
I would strongly suggest picking up a mono block amp to power the subwoofers, and then putting the 4 speakers on each channel on the amp, though.
