Setting Gain for my Sub Through a bridged Amp??
|
Silver Member Username: AfroopuffPost Number: 484 Registered: Jan-06 | I have a Orion XTR375 powering my 4ohm JL W3v2. There are 2 phase settings and 2 gain settings. The phase settings can be a 0 or 180* for the right phase, or a 0, 180*, or mono for left phase. There are also 2 gains in which to set,a left and a right. I tried reading the bcae guide to bridging your amp, but to be honest it was a little over my head. I still am not sure how best to set the phase and the gains? Thanks  |

Gold Member Username: •cam•BC Canada Post Number: 1566 Registered: Nov-06 | So you know how to bridge it? Set the left phase switch to mono, and you can play with the other one later. Not sure what to do with 2 gain controls on a bridged 2 channel. Maybe the right overrides the left when it's bridged, like the phase does. Gain is just an input sensitivity adjustment. On 0, it will drive power to your sub, just not much. Oh, yeah. Phase. When you get everything set up, try listening to it with the phase switch at 0 degrees. Pay attention to the midbass and how easily you can tell that there are subs behind you. Now flip it to 180 degrees out, and see if it sounds more like the bass is coming from the front of the car. Obviously, you want to leave it wherever the bass sounds more like it's coming from in front of you. |

I assume you don't have the manual for the amp. Here it is. Page 30-31 http://www.orioncaraudio.com/Support/Manuals/Amplifiers/XTR%20Series/Orion%20XTR 375%20Owners%20Manual.pdf |
