Hey, im new to the g35. I have an 04 g35 sedan 6mt. I'm having problems with my audio and I cant figure it out. First i dont know if the amp is blown. My back speakers get no power and my front speakers seem like they dont get that much power. Its hard to hear the radio when i have my windows down and if the volume is to high everything just seems shot. So my question is my amp blown? Or is it my radio or speakers. Thanks

 

nope that's just the Bose
based on the age of the car though it could be either the amp, the headunit or the speakers.
first, fade to the rear and see if your rear speakers are working. that will tell you right away if the rear speakers are blown.
at a certain point on the headunit you'll get more highs less lows, this is the bass roll off point, where you can still hear the highs (which get drown out by the wind) but you can't hear the lows due to road and wind noise.
if your rear speakers are still working I'd suggest going with an aftermarket deck which will remedy most of your issues.
Take a look at the stickies in the audio section as per what you need to get it installed.
Also you can PM me and I can walk you through how to do it.

 

the speakers work, just the rear (subwoofer) doesnt work. I just noticed the amp was unplugged to i plugged it in.

 

just decided to go all out with it and go with the dd kit and a jensen touch screen head unit, with infinity speakers all around.

 

there ya go... but don't buy a crappy headunit. head unit is the most important part of your stereo, for current and future use - keep future stereo goals in mind

 

head unit is pretty good. did my research as i ve been doing with this whole process lol

 

And replace the Bose amp with something aftermarket.

 

How does the wiring work with the aftermarket amp?

 

Run RCA cables from the radio to the new amp and tap into the wire harness after the Bose amp to send the signal to the speakers.
