Radio Turns off when Volume is too loud. Any Car Stereo.
Same thing happened when i used existing wires from a previous Car Stereo, to Hook up my New Car Stereo !!!!!!! BEFORE buying An Amp or Going Further, Please Just Verify All Wiring. If you do not have an Instruction Manual go online and search for wiring diagram, most manufactures of stereos post instruction manual and installation manuals. The verification of All Wiring is going to be the Major factor in the performance of your system. Do Not Assume former wiring is correct or is not compromised. Or if you did the wiring remove all covers and or under dash or under carpet etc. and Recheck for damage and Recheck all power & Ground and Speaker wires are All Perfect, somewhere a wire may of gotten crimped/cut etc. Keep It Simple. Take your Time and Go one by one and verify. Make sure the Accessory lead from Stereo is connected to a power wire that is only hot when in the Accessory mode and is an Accessory wire, Not a Battery Power Wire. To check an Accessory Wire turn key counterclockwise to Accessory and test wire you have chosen for this lead. Remember with Accessory Fuse is powering your unit, to check and double check in future that it is still not Popped or Blown. If an Accessory wire is not Apparent ? You can use the fuse to the accessory block say for the Horn, to wrap/loop the stripped end about 1 1/4" of wire IN A FIGURE 8 Pattern around the the 2 metal spades/prongs of the Fuse and push the fuse into its slot. Use A wire a little larger then your Stereo Accessory wire will work. 16 - 18 guage wire. Do Not leave too much bare wire exposed just so that the insulation of the wire does not keep the Plastic Head of the Fuse from securely being pushed into the fuse block. To check a Battery wire with key off this should be hot. If you have to Run a New wire to the battery ? Just do it as it will only be done so go for it. Find where the loom goes thru the fire wall and snake it thru. Then make sure the Battery wire is connected to a power wire from the Battery. Battery wire is only for memory of the unit, Not just Power. For Both Accessory and Battery Power Hot Wires, install an In Line Fuse, ( from Radio shack or other electronics store), install a 10Amp fuse inside. Keep these in line fuses easily available, do not push them up and tie off under dash after install where you can not get to them. Then Make sure that the Ground wire is Grounded to a Chassis/Body existing Bolt, (Bolts are better than Screws). Lot of bolts or screws up under dash that can be used as grounds. For ground connection use metal washers on each side of the electrical crimp connector you are going to use for the end of your Ground wire to assure a Perfect Ground. To test power and to find a good ground, use a simple Voltage Test Light ( an ice pick sharp probe on one end and in the handle a light, and at the handle end there is an attached wire with an alligator clip). The sharp tip is to push thru and into the insulation of the wire to the wire itself and the clip is attached to a bolt or screw that goes into the body/chasis for ground. If you are testing the bare End of the wire, use the Alligator Clip to connect to the Wire and the Sharp Point to push into the head of the bolt or screw. (the probe light can be used either way, all you are doing is making a proper connection at each end and the light will come On). Use this test light to verify either an Accessory or Battery Power wire that is used to attach to the wire you are verifying it is the correct power wire desired. Also will be used to find a Perfect Ground. Next verify all your Speaker wire is not compromised/scraped/crimped/cut or faded because of age. Go online if you do not have wiring diagram for your Stereo to verify If i did not verify my wiring first, i may of followed other advice here and bought an Amp and it Would Not of Solved the Problem of ....... Radio/Stereo turns off when Volume is tuned Up. It may seem at the time to use old or existing wiring without verification to save time, It rarely works out that way. Also you will have verified all wiring yourself and know where it goes and what it is connected to. Take your time and do it correctly.
