Hey guys, I had this indash dvd player installed for sometime and its always worked great. I have a 100watt mono amp hooked up to a 8" sub. I just added a cb radio to my truck and it worked great with everything, I then added a amp to the cb radio and now I get a error code and the radio goes into safe mode. This only happens sometimes. the code is "miswiring dc offset" So this code only comes up when I talk on the cb. I wonder if the amp is drawing to much and causing the voltage to drop and the radio to go into safe mode? anyone have any ideas?

After hours of searching I think the problem is RF. Now I need to try and keep RF waves out of my indash. Anyone try noise filters?

I would try beefing up your grounds

 

Btw i would love to see pics!

Also overdriving your amp can make alot of rf problems

All the grounds are good. The linear amp is hard wired to the battery with #8syou the indash is factory wired with a plug and play harness. My power inverter and sub amp are wired to the battery with #4s. I hallve dual 1000ca batteries ... and on and on. Ill grab some pictures tonight.

Im a electrician so I like to wire stuff.

Great!, have tryed lowering your dead key into the amp?

[jonny72888]

Yes. I had the radio ( uniden pc68xl ) peaked and tweaked to 25 watts and the dead key raised. When I got the linear I had the dead key dropped. Its a nice setup I have a 1.3 at channel 1 and 1.1 at 20 and 1.2 and 40. Once I get some extra cash im going to get a sideband.

 

Connected by DROID on Verizon Wireless
