siucsaluki11 Posted July 25, 2009 Report Share Posted July 25, 2009 Alright, well i got a friend who has an 01 shitsubishi (jk) mirage. It has a sony HU and a sony amp pushing a 12" L7. When the car is off, HU is off, voltage at amp reads 12.xx volts. When car is on with HU off. Its 14.0x Volts. As soon as the HU turns on the voltage drops to 7V. Where is the issue? They have been having problems with the amp cutting out, now im sure that is cuz the amp is going into protect because of the low voltage. Anyone got any suggestions or ideas as to what the problem could be? I took the amp out and put it in my car, it still works even though it is an explode Quote woman..cant live with em...cant shoot em...guess were all fucked You might be a Redneck if you use your leftover gutters for a speaker box port...

siucsaluki11 Posted July 25, 2009 Author Report Share Posted July 25, 2009 voltage at batt does not change when HU turns on, but voltage at amp drops to 7.xx Volts. Im confuzzled. Is there any chance something inside the amp is fuxored? The gains were maxed out, and the sub was wired to a final load of 8 ohms. Any and all help/thoughts/suggestions/whatever is much appreciated.

brsteinbach Posted July 25, 2009 Report Share Posted July 25, 2009 IDK but maybe wire the remote turn on to a fuse instead of the remote turn on wire from the HU. Just a guess.

siucsaluki11 Posted July 25, 2009 Author Report Share Posted July 25, 2009 ya, im workin on running a different remote. IT IS NOT MY CAR and I DID NOT INSTALL THIS. I tried swapping out my amp into it and as soon as the hu turned on, voltage dropped to 5-7v. And my gains are turned all the way down. Im beyond confused. Im gunna try running a diff remote (they had it off the remote for an amp of the HU, ill try the power antenna loop. Also, the HU heats up a SHITTON and still plays when the ground is disconnected. WTF is with that? Im thinkin they need a new HU but this is the first time ive really had to dig this far as far as trouble shooting a problem is concerned.

siucsaluki11 Posted July 25, 2009 Author Report Share Posted July 25, 2009 UPDATE+ If i touch the leads of my DMM to the power wire for the amp (its 4ga.) to the ground wire for the amp (also 4ga) when not connected to the amp i get a reading of 12.xxVolts, with the HU on or off. Now when i touch those 2 wires togeather, there is no arc, nothing.

Darksideofsound Posted July 25, 2009 Report Share Posted July 25, 2009 i think the HU is bad. try another HU. Quote Link to comment Share on other sites More sharing options...
sully Posted July 25, 2009 Report Share Posted July 25, 2009 check the head unit, if it does it with both your amp an his then the issue is with the remote wire or the head unit. With the head unit on what is the voltage at the back of the radio? or at the battery?

siucsaluki11 Posted July 26, 2009 Author Report Share Posted July 26, 2009 Problem was in the rem turn on wire. HU is a POS too. And the fuse holder had an issue. Its a shitty fuse type, it was an 80A fuse and it looked like the fuses in your cars fusebox or on your amp but on steroids. Well, one of the legs of the fuse was black, and there was some melting on the fuse holder. I told her tell her brother before he buys anything else, get a new fuse holder.
