Sure 2x250 Amp build

Re: Sure 2x250 Amp build

probably should have got some 2wire plus shielding for the inputs. Is 14 gauge fine? I don't even think I could get that in the board. Holes are really small.
Any opinion on why I'm get a clicking sound from the right speaker?

If 14 on the outs is a little big, 16 is fine. Inputs need only be 24-20 AWG.

Shielding is desirable for the input stage, as that can be detrimental after it gets amplified. Once the signal is amplified, the voltage
output is less affected by any close noise generation.

Shield the inputs, standard large gauge the outputs.

Agree on that, though I was going to give you a warning about managing the loose shield wiring that was getting a bit too close to the terminals... :eek: But, you've gone ahead and replaced them.

Most small coax of that size is pretty small on the inner conductor, 18-20g, and for this size amp, bigger is better.
