Ok let me start of I'm zack and I just traded my 2004 Audi a6 for a 2004 g35 sedan. So far nothing but problems, and I've been searching for a few days. Not new to the forums jus this one.So here's my problems

Drove fine for first few days. Tried starting dead battery, jump started drove home. Again still no start to leave. I don't have factory radio I have a pioneer double din.

Second my fuse box/ junction box in front of battery has power on both sides of all fuses. Also the previous peer had a small single strand wire wrapped between the radio fuse to bypass the blown fuse, any idea why?

Any help would be greatly appreciated

 

Welcome to the forum Zack, sorry for the slow reactions to your post. Sounds like a new battery would be a good start for your main issue. Be aware that ours has the poles "reversed" from normal so you have to pay attention to what you buy. Here's an example (expensive though, there are other options):

It is never a good idea to use wire to bypass a fuse so you should look into that "mod" right away. Good thing you found it. The guys in the audio section here are great so jump in there to get answers on radio issues.
