Re: Amp question
Assuming the Radio is being played through the amp?...........Depending on the type audio output the radio has and how it is hooked up and/or type of amp., just powering the amp down, most likely will simply mute/kill any audio signal going into/out of it. Very few, in fact, none that I can even recall go into bypass by powering them down and would require that the input source HAS to be capable of driving speakers. Just simply here, if the radio is hooked to the amp solely via RCA outputs, It will not amplify ANY sound because the radio's RCA audio output's HAVE to have an amp to even squeak!!
So a bypass can be made and then YES about a switch, but, the switch would be most likely be a 4PDT on the speaker wires AND use the standby of the amp or just cut it's batt power(either way) AND you to have a type A or C radio (see below)

Go into standby and flip the switch.
So, step at a time,
Radio(not amp), it has audio output wires of course,
Some types of radios have two sets of audio output wires, 1) RCA jacks(circular plug like guys with coax wire, red and white usually) AND 2) Regular like wires that would go directly to speakers.(We'll call this duel output radio, type A).
Other radio's just have #1 type outputs as described above and have to have amps to be heard((we'll call this RCA jack only radio, type B)
While still again, another type of radio just has #2 outputs as described above of just having only speaker wires that can be hooked straight to speakers or amps(we'll call this speaker wire only radio, type C)
Do you know what type, A,B or C your radio is?
