NSM; He probably isn't a tech.

Blake, these amps for the JBLs are not up to snuff IMO. The best thing
to do is to get an amp and feed it externally. I have a 112 and simply
feed it from the crossover of a speaker with a blown woofer. It is
great, the speaker and enclosure perform very well. I've had flat
response in this room below 30 for a long time, but this thing goes
even lower. I am very pleased with it.

Screw the amp, what's more get another one and use them on both sides.
Then you just hook them up with your exising speakers. If they are too
boomy get some crossovers for them. I wish I had room for two, I would
buy another fried out one to put on the right channel. I'd hook it up
the same way here, connected to the woofer output of a Boston Acoustics
A-150. It's funny, but the woofer in my right A-150 is actually
borrowed. So I could return it.

Actually you can get amps anywhere, but a superior speaker and
enclosure like this will work without the internal amp.
