agreed as well. With a good quality, relatively "hot" incoming signal, you'll need to definitely turn the input signal to high. On my 500/1 with a very clean and "hot" signal going in to the amp, it is definitely pushing the 500W rms it's capable of at about 1/4 gain.

you guys are DEF correct.. it is set to low, whats the diff i would have thought low would be better lol

what is clipping exactly? (ya i know imma nub)

i turned it down a bit and it stopped smelling.. but doesnt seem to be hitting as hard as it did with the older amp.

ohh and the subs are a few months old and the amp is a couple years old. First time the subs have seen this much power but not the first time they have been bumped hard.

running an old school panasonic deck that came with the car (Panasonic DF800U)

The overall gain range on a Slash series amp is 200mV - 8V. The low range is for 200mV to around 2V, the High range is for 2v-8V. Switch it to high and try at 1/2 gain. If it doesn't smell, turn it up a lil, if it does, turn it down a lil. The best way is to place on high then use the adjustment method in the manual. I'd think you could get away with around half gain on high setting.

A good signal has round peaks and dips, sub moves nicely up and down. When you clip the signal, the round peaks and dips flatten, which causes the sub to freeze at them flats which in turn burns the coil.

Keep it set to high and play with the gain. Your subs will survive. Good thing you asked early enough. Otherwise you would have baked a sub for sure.

No problem. If it is in a ported enclosure play around with the Xovers and "Q" control. Also JL has some recommended setting for their subs and amp combos. Try a couple of their recommended settings (click).

I'd set gain at half on high setting, infrasonic to around 30hz, LP filter 80hz, "Q" 1.1-1.6, center between 45-55hz, and boost around 3db. That should be a good start. You can fine tune from there.
