this is the case for my new subs
i own a dpx1851 amp 460 x1 4ohm and 860 rms at 2ohm. with the big 3 upgrade i still feel the car is stressed at 2ohms. so
i bought a set of new old stock wq2510d dvc 4ohm sub x2 i will be underpowering them by almost 50% so i was worried.
but got a good price at $75cnd each for them and put them in a bassworks ported box

im not going to win any spl but the bass for 2 10 is the best i have used in years. clean not muddy tight and loud imo super great value. i have own a ton of jl over the year and i would say these also sound alot like a w3 not wx or w0 or w1
for the cheap price these are a great set up.
i did install a set of these svc 12" in my buddy car with a tanturm 1200.1 so i thought they were going to blow up with how loud they were in a jetta. but a year later and they still rock
i have used focal 15spl,16k2", jl 10w7 12w6 jl 12w1v2 10wo 13.5 shallow jl, pg octane,rsdc,Alpine type r 10,rf punch 12,soundstream spl 10dvc,eathquake sws8" clarion sw1001 ect ect in the last couple of years.
it been a bit since i installed a set of subs that i really like with very little tuning ect
