avic-x1

Sometimes there's an unnaturally large spike in power consumption by speakers, normally from bass, and when that spike happens, you can't control how much power goes through the feed wire. Try upgrading the power wire and fuse by running it independently from the car's power source. Use about 20 to 18 gauge wire with a 15 amp fuse, and you should't have any trouble. I figure that this might already have been suggested, but it's worth a try. Just closely watch how much power goes to the AVIC, as you don't want to fry it. Another thing to look at is the cutoff freq's for some of the EQ bands. If there's too much power for one band, you'll blow the fuse. But, just like I said, you don't wat too much power going to the system and fry the reciever. Something else to remember: if that car is a Euro design, it's power rates fluctuate drastically compared to US made vehicles (it looks that way b/c you're using an X1, the euro version). That power flux could fry wiring too, especially without the right wiring.
