RCA's - the best way?

[Blados 10+ year member]

I have two amps, one for my sub and one for my component speakers. Is it best to use an rca cord for each amp, or can I just daisy-chain them (rca from input on one amp to output on the other amp)? Will one yield better results?

Depends on your headunit.

If the HU has built in features you would like to use (like dedicated sub output with built in crossover, level adjustment, on/off, etc), then it would be best to run a dedicated RCA to each amp from their respective RCA outputs on the headunit.

If you are only going to be using the amp's crossovers, and don't want to use any of the HU's built in features, then you can just daisy chain them.
