Im thinking of canceling my order for a Kicker 10" L7 & KX 600.1 Amp. This order was around $250. I could wait and save up and get a JL 12" W6v2 & 500/1 amp. I would have to wait some time because the JL system would be around $780.
i owned the 12w6v2 and its great for sq in a sealed. you will gain 3-6 decibals more in a ported and will sound nicer and give you more spl while doing it. However it will cost you alot more for it like you said.
for 250 bucks for the setup your looking at you cant beat it do that and save up for the jl while you have the kicker heck you might not need the jl amp with the w 6 if your desire is sq with the jl sub
