Sell all the JL crap
I paid $250 for my 12w3v3-4
then I tried on of the VVME RD-12's for $55
I sold the 12w3 instantly.
There is better for less out there.
and most people on here will bash off brands, but you can find more for less.
I had a boss onyx nx159DC 15" and that thing was awesome for the $50 I paid for it.
just be careful with craigslist. most people are idiots on there.
I had one guy tell me he had a 15" and it was only hooked up to ONE voice coil, and the box was 1.5" SEALED...the thing was blown. I got a q-logic box and the bind posts or whatever out of it though...
Make sure you test the stuff first.
tl;dr JL is over priced, you can find more output in subs and amps for FAR less than JL
also, you MIGHT be able to get those 2 different sets of subs to work if you run each pair on a different amplifier. a 1 ohm stable amp for the DVC's, and 2 ohm stable amp for the SVC's. I can't say for sure, but if you just want to go the easiest POSSIBLE route, this MIGHT work. But I would just sell everything, and get matching.
