I was wondering if someone here can give me some, or some more, advice as to this amp. I know JBL makes some good stuff but I can get this amp for $150.00 and I was thinking of useing it for a subwoofer amp. I found out that it is high passed at 50hz and was wondering if it would be able to be adjusted down to 20hz. I do need a center channel amp so it might just be used for that but if it can be moded for a lower frequency easy enough I would use it for the sub. Also if any one has opinions about JBL amps in general I would love to hear them....Thanks....:scratchhead: Amp info..

I used a Crown K2 amp for 4 years, driving passive subs, got really good bass, but they were full range amps, with the HT receiver providing the low pass xo.

But with that setup you only get the normal bass frequencies, not the LFE track.

I would suggest getting a sub plate amp, I'm now using Bash digital plate amps (500w) and they deliver as much volume as the 1600w K2, more efficient.
The 300w Bash is $125 at parts express
and 500w Bash is $185
When I was using the Crown K2, I had the subs connected in various wiring setups.
One was I had my pair of 4 ohm JBL SUB1500s wired in parallel to one side of the amp and a pair of old 8 ohm L55, wired in series, to the other side. So one side was looking at 2 ohm load, the other 16 ohm load.
Each side had its own gain control.
You would think so but if I have my amp gain wide open I can not get the level down to 75db with the master set at 0db. Let me know how you ended up after making your adjustments with your new amp.
You set up your gear so you can get the 75db level. If you can't get it with the power amp all the way up, then turn it down so you can. The volume level has to be controled by the preamp.
Its like with my Bash sub amps, the receiver's sub out is at -10db, with the Bash volume control only about 1/3. And at that, the sub is about 5~6db hotter than the other channels, which is how I want it.
