Sup dude,
Since everyone nowadays is basing price on ebay here it is:
JL 500/1 MONO BLOCK AMP.
~$350
JL 300/4 AMP.
~$350
JL W6V2 SUB.
~$800
JL 6X9's TR series.
~$90
JL 6.5's XR series.
~$100
JL 1's Noedium tweets XR series.
JL crossovers XR series.
Sorry bro, don't have pricing on the last two.
You would prob get more if you restocked the car.
Good luck and I hope this helped.
Peace
RIL
