yes it sure does....more capatence, more output devices, also looks to have a bigger power supply.

But with that said circut design plays a huge factor too...

jl 300/4: rated 75x4
rsd 300.4: rated 50x4
rsd 500.4: rated 75x4

Is it just me or does it look like the 500.4 has the same number of output transistors? In fact, they both look identical aside from a smaller power supply on the 300.4. Maybe the transistors on the 500.4 are bigger?

thats because the JL is regulated in and out also prob why the JL looks a lot more beefy. Simple is better IMO when running signal through an amp....which RSd seems to have the edge there.
