Was setting input sensitvity and..

[osokrayzay 10+ year member]

Hello new to the forums. Was mainly a lurker. Now that i need help i decided to post and hopefully somone is able to help me.

My setup consists of Kenwood kvt-911, jl 1000/1, 450/4, 13w7 slot ported 2.5 cubes tuned at 30hz. Jl audio 5.25 rear and 6x9 doors.

I have had this setup playing nicely for a week. I decided to adjust the sensitivity after reading several thread here. Was following along the jlaudio guidline, I was never able to get past 8,9 volts and my target was 54.7 volts for 3ohms so i gave up and put every setting back the way i had it. Well now I have no output on both my amps, there is power going to them, Green light is on. If i turn it pretty high you can sort of hear it? I dont know what to do now. I checked the rca plugs, gorund wires, settings, im just man i dont know pissed. Please help.

I know its my first post coming in here and asking for help but pls do..

Do you have the correct sensitivity range selected on the amps? If you were only able to get 8.9V and you wanted 54 then that is where I would start. You also need a 0dB test tone playing while setting everything.

The senisitivity is on low. I was using a bassmekanik cd 50hz sine wave. I dont know if it was recorded at 0db. But my main issue i set everything back the way it was and no sounds from the speakers.

Well, without being there and able to fiddle with it personally, I'm at a loss.

Are you sure you are setting your multimeter to AC power and not DC?

 

[osokrayzay 10+ year member]

yup i have it on AC and V. I went outside to try againg now i ahve a reading of 0 //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif . But theres still power.

Same problem with both amps?

 

[osokrayzay 10+ year member]

yes sir. When I turn on the truck, you can hear a thump and then if i switch like to dvd or tv tuner and back to radio at each switch i can hear a thump.

 

[nweibley 10+ year member]

Go inside and measure your walls voltage. Is it reading like 115v? I'm not so sure your meter isnt a decimal point off, and you arent setting it to 83 volts if you are hearing the switch from source to source.... of course, that could be indicative of another problem.

Sounds like your HU went south on you...

Oh man. I just ran the 6x9 of the deck and not the amp and those works. So that means its prolly in the main unit not the HU. Hmmmm.

Well messed around with a little more and ran out of sunlight. Imma get up early in the morning and check fuses, wiring , etc, see what i can find. I e-mailed jl see what they say. If any of you guys have any suggetsion on what to do or check pls let me know thx.

Ok, but I still want to know if your multimeter if fubar, or if it is a component in your system is fubar. Did you get a wall socket measurement?

What HU are you running?

 

[osokrayzay 10+ year member]

New mutlimeter. Just bought it today. I dont know whats messed up, something is tho //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif. Wall socket read out 122. 4 volts. HU =kennwood Excelon KVT-911

If it is both of your amps, the problem has to be with the HU. Make sure you didn't mess something up in the settings (especially the odd ones) that would mute the RCA outputs.
