Looking at your mods I don't know what JL 6W0 means, can you clarify?

Other than that I don't see anything to warrant changing from the stock plug.

its a replacement subwoofer from JL Audio, had to mod the enclosure a little because of the larger magnet but a big improvement over the stocker once its fully broken in. The best sub suited for the stock enclosure/amp.....FACT.

you have to wreck the old sub though when you remove the plastic ring to use on the JL

I concur.
Not a single thing in his mods denote a need to stray from stock heat range plugs.

Lidio always recommend going to a one stage colder plug on his 93 octane tune along with a 180 t-stat at least that's what he told me when I was shopping around for my first tune years ago.

Whatever plug you get make sure you get the GMS coil connector plugs also while you're at it. If you order the plugs before installing them make sure they are gapped right, I believe TR55IX should be .052 gap, if one or more isn't don't install them yet until you get a correct one. Don't forget anti-seize and de-electric grease also.

Some may say Iridium plugs aren't worth getting but I don't feel like changing mine often. I had TR6IX (one step colder) plugs I think they were in for 70-80k miles and looked just how they were suppose to when I replaced them. They recommend if you daily drive your car or drive it gentle 100-120k miles, if you race it or have a heavy foot often 60-80k miles change interval.
