JL Audio makes a great Sub & Amp.

Biggest thing is to make sure the Amp's RMS matches the Sub's RMS at the right ohm. Probably 4 ohm.

I have a 300w RMS JL Audio Sub in a corner mounted sub box made of 100% fiberglass. You really don't need more than 300 watts RMS IMO, unless you are a bass head.

The other piece to the puzzle is getting mid-bass subs underneath the seats that play nice with your corner mounted sub

Right now i have the original JL w3, (yes version 1) it's good but wanting something little more bass.
Have you plugged it in w/ the amp? The fiberglass encasement makes for a tight & clean base. You could stuff the encasement, if it isn't.

What's the RMS on the older JL Audio sub & your amp?

Also, what are you running for underneath, seat subs?

Everything factory other than head unit (Eonon) jl sub in fiberglass (it's pollyfilled) amp JL rd500/1.
I think you will want to explore underneath sub options and have them play mid-base (80-90 - 250)

Then cross over your corner mounted sub at 80-90 down to 30
