Is the ZR1000.1D worth it for a first sub setup?

Yes, if you want a small, cheap mono amp to power one subwoofer. It is not the choice for big subs that need lots of clean power.

Can it power my door speakers too?

No. It is a single-channel amp, so it drives one subwoofer only. You need a separate amp or head unit power for the other speakers.

Start with the bass boost low and raise it gradually while listening. Too much boost can distort the sub and strain the amp.

Match the sub's impedance and power rating to the amp's rated output. A single moderate-power sub in a sealed or ported box is the typical fit.

Expect the amplifier and basic mounting hardware. Wiring kits and remote bass knobs are usually sold separately, so check before buying.
