The resistors are pretty low..
But that is not your problem..
If you installed LEDs with out the Load reasistor you would be getting double flashing..

Since you install car stereos you might have the load resistor hanging around..

Try like 10 ohm 25 watt...
Used as a passive crossover..

Sorry but I did say 25 watt!!

couldn't you use 4 10ohm 1 watt resistors wired in parallel to make the equivilent of a 2.5 ohm 4 watt resistor? I don't know what you have lying around but I thought that might work if the 1 watts were just a little to small.

also, is there any difinitive answer of whether we should wire it in series with the light or as a load (parallel)? it would seem that the load would not dim the leds whatsoever while wiring it in series would.

Kits I have seen have two resistors.
One for each side.. I wonder if you could just use one at the flash relay itself..

BTW they sell non current sensing relays and adjustable relays too..
