mtxcivic07 Posted April 27, 2007 Report Share Posted April 27, 2007 I have had my input sensitivity on on my MTX 7801 Amp at 10x since I have owned it. I have an Alpine CDA-9847 CD player. On MTX's site it says to keep it at 1x when you have an aftermarket CD Player for sufficient voltage feed, but it is not loud at all when it is on 1x and when it is on 10x it over heats after about 10 minutes of play at full tilt.. what should I do? what do you guys keep yours at? 18's in a wall to come....Its not all about the posts....check the member #...

roscoe1129 Posted April 27, 2007 Report Share Posted April 27, 2007 well i am not sure what 1x and 10x is in regards to the input sensitivity cause most amps use a number ie .1 thru 5. volts for input sensitivity. Some people need a sympathetic pat... on the head...with my hammer Scientia est Vox "In Nomine Patris et Filii et Spiritus Sancti" DONT BE AFRAID TO USE THE SEARCH BUTTON!!!

Chris Posted April 27, 2007 Report Share Posted April 27, 2007 1x is 100mV-1V10x is 1V-10V Mine is the same way as you man, it's a lot quieter on 100mV than 1v+ 4 15" FI Q D2's in 12 cubes tuned to 32hz 1- T1000.1bd's 3 Maxx 29 deep cycles 4 runs of 1/0 gauge -Big 3 -Trunk sealed off from the cabin Custom 15.8 dual-volt switching MLA module All in a CAR.

roscoe1129 Posted April 27, 2007 Report Share Posted April 27, 2007 R those the only two levels for adjustment? I mean most amps have a variable knob adjustment that u can adjust anywhere in between those two points Some people need a sympathetic pat... on the head...with my hammer Scientia est Vox "In Nomine Patris et Filii et Spiritus Sancti" DONT BE AFRAID TO USE THE SEARCH BUTTON!!!

Chris Posted April 27, 2007 Report Share Posted April 27, 2007 How about the HU? Is there a menu to select line-output voltage/strength possibly? 4 15" FI Q D2's in 12 cubes tuned to 32hz 1- T1000.1bd's 3 Maxx 29 deep cycles 4 runs of 1/0 gauge -Big 3 -Trunk sealed off from the cabin Custom 15.8 dual-volt switching MLA module All in a CAR.

sean 371 Posted April 27, 2007 Report Share Posted April 27, 2007 You are supposed to match the input sensitivity to the voltage of the preouts on the h/u.
