I have a Bose Acoustimass 7 (I know, I know it’s Bose 😏but for the ease of having them mounted up high and the sub box behind a chair, it is practically invisible amd sounds amazing in my small 100 sq ft area. Plus I’ve had them for years so might as well use them ) in my pool house . And 2 Klipsch AW650’s outside. I want to be able to have a multi-zone amp to power them all at once with a “2” sub output. That way my Polk Audio 10” sub can suffice inside and I want to install an all weather sun outside to help the Klipsch gain some boom. So I’m thibanking a 7.2 or that range of channels. What’s out there to power the 85 rms klipsch and the 3 ch Bose with dual sub outs ? And a tight budget I must keep with …. Thanks
