POWER SUPPLY UPGRADES
This is a very important area that most people over look. Large amplifiers require large current demands.
Deep cycle batteries, like Optima’s are designed for continuous high current applications. They will also start and run your car much better, as well as lasting a lot longer.
Audio capacitors will also boost your battery power and increase the flow of current to your amplifiers. In many cases these items are not an option. They’re a must!
