10 In Jbl Car Subwoofer I Need Some Car Audio Advice?

I need some car audio advice? - 10 in jbl car subwoofer

Currently I have 2 10 "subs and a dual 12" subwoofer JBL

I have connected to a Sony XM-280GTX Amp

There are three small adjustment buttons on the back of the amplifier, and wondered what would be the optimal settings for these are without prejudice to any of my computers. I'm sorry, I can not remember what any of them are marked, as I am stuck at work, but if someone could help me it would be nice.

Thank you!

Master Lock Change Code I Have An LG-TM250 Flip Phone And Can't For The Life Of Me Remember The Unlock Code. Anyone Know Of A Master?

I have an LG-TM250 flip phone and can't for the life of me remember the unlock code. Anyone know of a master? - master lock change code

It has 4 digits and it was changed 6 months ago. The problem is that I am leaving the country for 6 months and the phone are set to lock automatically when switched on so that it can not not see the code with the phone! The company said it would pay for and for the service or buying a new phone, but I'm sure there must be a master code or a combination of keys, which can override security ... Suggestions would be very grateful!
