Summary: These speakers hit hard!!! I put these subs with the jl1/1000 amp. But I put them in a very cheap box.. take my advise get the best box u can find.. I got my amp turned up about 1/4 and sounds like the box is about to blow up! I was told by the I installers I need a box twice the thickness.
Deep, unimaginable bass that you have to hear to believe

Summary: I have 2 of these bad boys in my car each on a jl 500/1 and they sound incredible! I rocked 2 12W3s for a couple years before I upgraded to these, and now I couldn't imagine looking back. One of these does what 2 W3s can do.
Conclusion: I paired this JL Audio SGR-12W6v2 sub/box combo with a JL Audio XD600/1 amp. I installed it rear facing in an MKV GTI. This thing hits so hard people in other cars think they have a sub too. Amazing sound quality. Crisp, clean, fast responding bass.
