I read an amp manual once that said you should change your battery ground to chassis wire to whatever size awg wire you used to install the amp.

keep in mind that the engineer who designed the wiring system in the vehicle did not take into account an xtra 800 watt, 20 to 30 amp draw on the electrical system, he designed it to handle the load on the devices installed by the factory, the big3 improves or eliminates your issue about 95% of the time, so just do it...

Try the cheapest and easiest fix 1st.........clean your battery terminals and report back.
