SentraGuy Posted January 15, 2011 Report Share Posted January 15, 2011 Let's see if you can figure this out, because I sure can't. Sorry about how long it is, I wanted to make sure I was thorough. Here's some background: -I drive a 2006 Nissan Sentra. -I have a Fi BL 12 powered by a SAE 1200d in the trunk. Sounds awesome... ----My car has the "premium" sound system installed from stock. This means that a small Rockford Fosgate amp in the trunk is powering the front speakers. It also means that the signal for everything but the sub is being double-amped. You would never know though, the highs are clear as they were before. (More on this later) On to the real problem.. I bought a Kenwood Excelon KDC-X794 to replace my stock head unit about 6 months ago. It looks and works just fine (When it does work). But about 3 months after I bought it, I kept blowing a small 10 amp fuse (Fuse #1, it says "ACC, Mirror" next to it) in the fuse box under the steering column, EVEN at LOW volume, and sometimes with no bass hitting. I called Crutchfield tech support (Awesome people, btw) and he first told me that I had not grounded the headunit right, because the stock harness in the car is not grounded, as this is what I used for a ground, and the headunit was trying to use the antenna for a ground as back up, and this is what was blowing the fuse. (Can you say run-on?) So I regrounded to a bolt behind the head unit, and then powered up the head unit with the antenna UNPLUGGED, so this must mean the ground is fine. Well, the fuse kept blowing. I called Crutchfield back, and talked to the same guy. He was baffled as well and told me to send the HU back, as it could be defective. And so I did. And they sent me another free of any charge. I installed the 'new' one, and couldn't have been happier. The fuse was not blowing, even at full tilt. This lasted a while. BUT, oddly enough, about 3 months after I installed that one (today), the same fuse blew again, at low volume. Here is what I think it MAY be: - Something to do with the signal being double-amped. Although I just have the small stock speakers up front. -Two of the times it blew, I was playing the same song (Mi Casa, Tu Casa) but one time the volume was only at about 10/35. This song may have been playing some of the other times, I don't remember) COULD be a coincidence. -Something wrong with how I wired the harness, although I repeated how I wired it to the Crutchfield guy, and he said I did it right. -The guy from Crutchfield said that fuse (#1 under the steering column) should normally pull less that 1 amp, so something must be going drastically wrong for it to spike to over 10 amps at random. If anyone can help me out at all, I will be very much appreciative. This is blowing my mind and I am running out of options. Quote Link to comment Share on other sites More sharing options...
zayres29 Posted January 15, 2011 Report Share Posted January 15, 2011 i would say trash that "premium" audio and replace it all i hate the factory radios are now with all the fancy nonsense Quote Btw that was the first person. Ever banned by me while dropping a deuce. Feel privileged Link to comment Share on other sites More sharing options...
Coolwazabi Posted January 15, 2011 Report Share Posted January 15, 2011 By no means i'm an expert here but maybe some of the wiring is exposed and touching either metal or other wires. From my experience this is what would happen. OR maybe that song is really clipped ?? idk does sound tricky. Quote Link to comment Share on other sites More sharing options...
C-Fizzy Posted January 15, 2011 Report Share Posted January 15, 2011 best bet is a short in the wire. did you heatshrink the exposed wires? Quote under construction I hate People with crappy primered cars rolling on hubcaps that are louder then me. u hate c-fizzy? Link to comment Share on other sites More sharing options...
SentraGuy Posted January 15, 2011 Author Report Share Posted January 15, 2011 i would say trash that "premium" audio and replace it all i hate the factory radios are now with all the fancy nonsense This is my plan. But, will be in the future since it will cost some $$ because I want it done right. No cheap junk. And having to rewire all the speakers to the HU frightens me to be honest.

SentraGuy Posted January 15, 2011 Author Report Share Posted January 15, 2011 best bet is a short in the wire. did you heatshrink the exposed wires? Yes. Electrical tape/heat shrink on all exposed wires. So, unlikely, but I will double check this when I pull the HU back out. Quote Link to comment Share on other sites More sharing options...
Rebel4055 Posted January 15, 2011 Report Share Posted January 15, 2011 Yikes, just electrical tape holding the wires together? Might want to solder them or crimp them... Quote Rest In Peace mother.

SentraGuy Posted January 15, 2011 Author Report Share Posted January 15, 2011 Yikes, just electrical tape holding the wires together? Might want to solder them or crimp them... Oh no no no. They are definitely soldered. With electrical tape covering the exposed wire. Quote Link to comment Share on other sites More sharing options...

They are definitely soldered. With electrical tape covering the exposed wire. Oh ok. double check and make sure there is no wire touching anything tho, a little slit in the wire could cause issues.
