www.inphaseaudio.co.uk, site isn't even working. And they call them frequency converters instead of voltage converters, haha. The 6-ch one at least is a little better documented, https://www.caraudiocentre.co.uk/pro...c6_p-27541.htm , "Max Speaker input 60 watts @ 4 Ohm". So assuming the SRCA Pro and SRCR Bass would be similarly spec'd if fully qualified, yes, definitely too much power on that Bose sub channel for them.
