I got a 600W Malibu low voltage transformer powering my landscape
lights. But some of the lights further from the transformer are not as
bright. I only have a single 12 gauge wire with all the lights
attached on it.

Can I attach another 300W transformer at the far end of the wire so
that the lights there will be brighter?

I cannot really run another wire from the 600W transformer, since much
of the wire run under concrete pathways and also my driveway.

Thanks

You don't specify the total connected wattage, but #12 is only good for 20
amps and a 600 watt transformer can handle up to 50 amps. You can't connect
another transformer to the existing wiring, but you can cut the existing
wiring in half as Paul Franklin suggested, and either connect the second
half to a new transformer, fed by a new underground line, or just run a new
underground line back to the 600 watt transformer, assuming it's large
enough
