Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3023 Registered: Oct-05 | i was driving, with my subs and box out of my car, cause i have been making a new one... so i was driving, and all of a suden, i heard a loud static noise, like for 2 seconds, and it was like as loud as i had my music. and when that happened my HU turned off, and so did my amp....... what the F@ck happened??????????????????????????????????? i turned on the car, and my HU and amp still wasnt turning on... i had my speaker wires from my amp hanging lose, so i think they might have touched, what could have happened??? |

Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3024 Registered: Oct-05 | yea. ok. i did a continuity test on my fuses on my amp, and the DMM beeped meaning that they are fine. so i can rule out that my fuses are fine, likely meaning my amp is fine too. i smelled my amp etc, and didnt smell any sort of smoke or anything, so i think my amp be ok. but how would i check my HU?? because its not coming on!!! isnt the HU supposed to have some sort of protection for if the speaker wires to touch?? |

Silver Member Username: TweekerPost Number: 351 Registered: May-06 | i thouht youre headunit and your amp worked when you turned the car on? connect your headunit straight to the battery see if it turns on jexx reccomended this to me when a headunit iinstalled was screwed... i dont know if you know how to do that thouggh, thats pretty much the only way i know how right now lol. |

Gold Member Username: James1115Ct Post Number: 6081 Registered: Dec-04 | well check the fuse in your fuse box for your radio it is prob blown. Does your amp light turn on when you turn on the ignition? I would bet on blown radio fuse. |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3029 Registered: Oct-05 | i checked the fuse behind the HU (10a fuse) and its not blown. but i havent checked on the one in my fuse box yet. and yes, my amp doesnt power on when i turn the key on, but for me, if my radio isnt on, my amp doesnt turn on, so thats why i think my amp is fine since the fuses are fine etc. how could (when the speaker wires touch) affect the HU in anyway? does it go through the REM wire or somthin?? i'll check my radio fuse |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3030 Registered: Oct-05 | and i just check the "radio" one, and the continuity is around 1.2. and the DMM beeps. anything else? |
|
Gold Member Username: James1115Ct Post Number: 6097 Registered: Dec-04 | yup it couls easily flow the radio fuse. Most good installers will add in a inline fuse to the remote wire. |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3032 Registered: Oct-05 | radio fuse isnt blown..... so what else is there to do? |

Gold Member Username: IlluminatorUSA Post Number: 4047 Registered: Apr-05 | You might want to try removing the head unit and hooking it up directly to the battery or another known working 12v source (only the yellow battery constant, red ignition, black ground) to see if it gets power. It might be worth opening the amp up to see if you can find anything that is physically damaged. Usually, when wires touch like that from the amp, the caps in the PSU blow. |

Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3034 Registered: Oct-05 | PSU? what are the steps for finding out if my HU or amp works... how do i hook it to the batt, for both amp or HU |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3035 Registered: Oct-05 | cause i have a feeling that my amp is fine, and that my HU is not, because my amp wont come on anyways if my HU isnt on soo.. |
|
Gold Member Username: IlluminatorUSA Post Number: 4049 Registered: Apr-05 | PSU=Power Supply Unit This is going to sound out of the ordinary, but it works...can you physically hook up your head unit to the amp's power and ground wires? Ah yeah, to test the amp, hook up the remote wire directly to the amp's power wire. It should turn on. If it doesn't, it's blown, if it does, try hooking up a portable CD player and see if you can get any sound out of it. This is all assuming your amp's power and ground wires are getting power. |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3036 Registered: Oct-05 | yea ok. i hooked the REM to the batt, and then all of a suden, my HU went on... thats weird i thought, because before the HU wasnt even turning on, hmmmm, and when i did that, the amp didnt turn on, so then i hooked the REM to the PW and the amp again didnt turn on... does this mean my amp is blown  |
|
Gold Member Username: IlluminatorUSA Post Number: 4051 Registered: Apr-05 | I wonder if the amp was shorting out the head unit because it was sending power back to it through the REM wire? Not entirely sure about that. Do all of the other functions on the head unit work? Do you know how to open the amp? I highly suggest you open it up to see if you can find anything bad before concluding that it is blown... |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3037 Registered: Oct-05 | ok. i will check that, and post it bak on here |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3040 Registered: Oct-05 | all the functions on the HU work fine... i opened up the amp and i dont see anything thats weird etc. i was looking for some black marks or somthin andi couldnt find anything. even if i blew the channels or somthin, the amp should still turn on.. could i maybe have a bad REM wire? shorted that out? and so thats why its not turning on?? -- i think that might be a good assumption |

|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3042 Registered: Oct-05 | thats the only thing i can think of, since my amp doesnt turn on, and nothing looks to be blown. jexx, what do you think? -- possibly bad REM wire? or Power Atenna? thats the only ting i can think of now |
|
Silver Member Username: TweekerPost Number: 360 Registered: May-06 | bassman you checked the fuse uder the hood im sure? somethmes they loked fine but they dont work change it and see wut happens cause in know its happened to me. get on aim real uick so i can tell you wut else to check for lol |
|
Bronze Member Username: OglejustPost Number: 20 Registered: Aug-06 | take a small piece of wire and connect it from the rem to the power on the amp. if it doesnt turn on than ur amp is probably f*cked. |
|
Gold Member Username: IlluminatorUSA Post Number: 4078 Registered: Apr-05 | ^Yep, check the fuse under the hood. If there is something else you can hook up to the power and ground wires for the amp that takes 12v, that would be a good way to test the wires. If the wires work, your amp is probably fried. |
|
Gold Member Username: IlluminatorUSA Post Number: 4079 Registered: Apr-05 | Didn't see justin's post haha. |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3043 Registered: Oct-05 | how do i test the fuse under the hook on my PW?? i have a DMM, do you know how i can check it? test it just like a reg fuse? -- doing a continuity test... and how would u know if they wires work by hooking them to a 12V source? -- Im just gonna use the batt BTW |
|
Gold Member Username: IlluminatorUSA Post Number: 4081 Registered: Apr-05 | Whatever you hook the wires up to...if it works, then the wires are good and none of the wiring has been fried. You're hooking up the amp direct to the batt? Sweet. Tell us how it goes. |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3044 Registered: Oct-05 | i already hooked the amp REM wire to the batt and the amp didnt come on. i checked the fuse under the hood and everything is fine... i just dont udnertstand how my amp would be fired if no fuses in my whole car aren't blown and i know, but how would u know if the wires work? |

Bronze Member Username: ToomuchsoundStaten island, N.y. Usa Post Number: 67 Registered: Feb-06 | the easiest way to save a headache pull everything out and put it in your friends car if they have a system jus hook your amp up in their car |

Bronze Member Username: ToomuchsoundStaten island, N.y. Usa Post Number: 68 Registered: Feb-06 | the easiest way to save a headache pull everything out and put it in your friends car if they have a system jus hook your amp up in their car do a swap test |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3045 Registered: Oct-05 | thats the same thing if i were to just hook my REM to a constant 12v source, and if my amp doesnt come on, its gone. i would be wasting my time if i do that, unless my REM wire screwed up?? |
|
Silver Member Username: Van_manBoston South, MA Post Number: 811 Registered: Mar-06 | Use the DMM to see if you have 12vlots to the amp, 4 or so on the rem, and ohm out the ground wire. That will tell you if its a power or amp problem. Quick and simply without removing stuff. |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3046 Registered: Oct-05 | what do i touch to what? for the ground... and for the rem.. and for the amp... thanks |
|
Silver Member Username: Van_manBoston South, MA Post Number: 816 Registered: Mar-06 | Disconnect wires from amp and take readings here.  |
|
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3065 Registered: Oct-05 | does that mean for the power wire you connect the PW to the + of batt? and what should that read about |
|
Silver Member Username: Van_manBoston South, MA Post Number: 819 Registered: Mar-06 | Huh? Ya, the power wire that feeds your amp should have 12 volts or so on it. The power wire is always hot,(Live), the rem wire should have 4 or so but only hot when the HU is on, and the ground wire should have a good connection. the way to tell is by using an ohm meter on the DMM, Gee, You should know this stuff by now. You messing or what? |
