Question about Car Amplifiers
Hi. First post. I HAD an old Qwestar crappy Stereo/MP3 head unit hooked up to 4 decent Inifity speakers, a 200watt Kenwood AMP and one big 10 inch subwoofer in an enclosure in the trunk. One day, their is no power to the stereo at all. I tried everything (as far as pushing buttons/fiddling with the faceplate) but I could not get it to power on. FYI - when I took the faceplate off, the 'fake alarm red blinking light' was blinking - which is normal when taking off the faceplate. The CD tray would even accept cds but wouldn't play them. They would stay in there until I pushed eject. Well, I was tired of this Qwestar (Circuit City) POS (it was decent enough but the LED/LCD was flaking out and the MP3 navigation was SLOOOOOOOOWW) - so this was my excuse to tell the wife that I was off to buy a new stereo for the car. I searched high and low and wanted a unit that would at least play MP3s through a USB port. I settled on the Sony CDX-GT610UI. As far as I know, I have hooked up everything correctly. I have followed the instructions in the Sony box and also consulted a couple of different, thorough install sites (big thanks to www.installdr.com) - everything seems to be hooked up correctly. FYI - the old Qwestar - when it was installed, the installer (Circuit City) installed a standard wiring harness so it was really easy to match up the wires, etc. I have attached the RCA cables (red/white) to the back on the RCA IN holes on the back of the unit - however, the only thing (just my theory) that might point to a problem is a tiny wire running along the side of the RCA cables - I'm assuming this is a low voltage power wire? I have matched this up w/the AMP REM wire running from the Sony unit. Otherwise, all of the other wires matched up with the wiring harness. So... I turn on the key, no power/lights come on the Sony unit. HOWEVER, it will accept (auto load) a CD/disc and it will also eject it. But that's all the functions it will perform, given it's current configuration. I realize that the old Qwestar unit most likely suffered from the same problem and that I most likely didn't need to replace it afterall. Also, I have checked all the fuses (near the floorboard) and nothing has blown. Not sure if there are other fuses to check. Also, the amplifier is powered up through a direct connection to my battery. I guess that is all the information I have for now. ANY HELP WOULD BE MUCH APPRECIATED! I bet this is an EASY fix but I just don't know what else I can do. Something tells me it might have something to do with the grounding??? I'm stumped. Thanks in advance! Sorry for the long post!
The rca cables that thin littel wire u can use it to turn on your amp so it will go the redio amp rem wire and back to the rem for the amp.
