Hi!
I am currently in the process of building a 2.1 channel bluetooth boombox and am looking into using some form of active crossover to save weight/space/cost in giant passive crossover parts.
I have been looking into Sure/Wondoms Jab5 amplifier which specifically has a 2.1 channel mode which is potentially perfect.
My question is, is it possible to use this amplifier in a configuration where each stereo channel is split into a tweeter output and a woofer output with a separate subwoofer output? Obviously with the main goal trying to avoid using passive xover components, each driver will need to receive its own signal. I keep reading that one of its intentions of use is as an active xover amp but cant see how you would essentially wire the tweeters separately to the woofers.
If this is not possible then the other option is to use "Sure Electronics Audio Digital Signal Processor Kernal Board - ADAU1701" outputting to separate amplifiers. If I have to go down this route then is there a way to wire my amps directly to this board without the use of the "Sure Electronics 2 x In, 3 x Out Digital Signal Processor Extension Board"? Every example I have seen online uses this extension board but it only has 3 outputs which isnt enough. (Left tweetet + Right Tweeter + Left Woofer + Right Woofer + Subwoofer = 5 outputs)
I know this is a lot to ask but any guidance would be massively appreciated as im a bit stuck with understanding.
Thanks in advance!😀

For most boombox approach they are using 2.1, which is 2 full range speakers and 1 subwoofer. However most if these boards don't have frequencies which you can tune to your liking. In fact not even sure the subwoofer amp even has filters. Those that could would imply you are doing it for hifi. So best I can suggest is passive crossover for the woofer + tweeter and active for the sub. Otherwise go for the full range route.
Sorry can't help you anymore beyond that.
