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..

... Right now the level in the reciever for my right and left channells are both -10,the lowest it goes, should I set the levels to 0 and then turn down the amp more or is it better to leave the level in the reciever at -10 and turn up the gain on the amp to achieve the correct level. Or does it even matter. It sounds great but I was just wondering if there is a right and wrong way to do it ?????
I would like to know the answer to this too :bigsmile: (I just installed my Amp and will tweek this afternoon).

I think that to get the best out of the external amp the gain has to be in the full/open position or close to it :yes: (according to other post I read before) :bigsmile:
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.
:sad: .... I didn't have time to play with the toys; I had to cut the grass and do some cleaning on the backyard (I started around 5:00pm and ended arount 8:30pm) ... but I let you know as soon as I do it :praying:

I just started a new thread to get ideas of what happenend here

Amp gain is fully open ... AVR did the autocalibration, but when I tested manually the reading was "85.0db and 80.0db", I had to lower the volume to get 75.0db ... so my reference will be at -10.0db :yes:
I just bought another amp today to run my sub. I got a Crown XLS 402d for $185 off ebay. It does 1140w bridged at 4ohms so it should work well with my sub.:yay:
