Looking for ground in 2003 corolla

[BROWNGUY]

I have a bad feedback noise coming through on my 2003 Toyota corolla. If there a good spot in the trunk to ground my system so it will eliminate this annoying noise. It only makes the noise when the car is started and not when off. It also gets louder as I hit the gas. If you know of a good location to ground please let me know and if you have a pic thats even better.

Thanks all....

My amps are grounded just underneath the rear seats. The seat pulls up easily, and you just have to sand a little bit to create a good contact.

I had it grounded there but I kept getting feedback coming through for whatever reason. I will try sanding it more and regrounding there. If you get a chance can you post a pic of where you have it ground cus Im all outta options and at the end of my rope with this feedback.

Ground loop issues need to be "tracked down". Experience helps. Hey! We have that kind of experience. Maybe you should come see us.

I know what the problem is and how to solve it what I wanted to know was a good location to ground without taking my trunk apart. Thanks for the help though.
