I am looking to have speakers out by the pool and I have the Sonos Connect amp, a TIC GS50 passive sub and two Polk SAT30 speakers outside by the pool and looking to connect them to Sonos. But with the sub being a 125W RMS/250 peak with 8 ohm standard and 4 ohm with satellites, and the satellites being 8 ohm compatible 100 watt..... I am seeing that I need to get an external amp to power mainly the sub. Any help on how much of an amp I need ? I have found some external amps that can provide that are fairly inexpensive (under $100) and will automatically turn on and off....but just not sure how much of an amp I need.....?? I am assuming I only need the additional amp for the sub as the satellites would go directly to the Sonos Connect Amp. If the RMS for the sub is 125 W, and the Sonos Connect is 55 per channel, would I then only need 60 watts from the external amp ?
Not sure if it makes a difference for anything but the wires coming from the sun are L +- and R+- (so four wires).
Any help is appreciated !
