A few electrical questions

**synfullj187** · 10-06-2014

I have a 99 gtp.

My rear speaker's come and go like there's and connection issue. I was looking for a amp. But I've had no luck. I thought it was somewhere in trunk?

Also my HUD that displays my gauges on the window will come on for a bit then go away. Is there a module that controls this. If so where?

if you have a non bose and its a premium system it will be behind the glove box.Get a different amp and run the speakers off that if you have an aftermarket headunit.
