[QUOTE="Blackout67, post: 8893055, member: 683415"] Best way to be safe is to either get distortion detector (they are expensive tho, the DD-1 that is popular is like $120), buy an amp with a clip light so you are making sure you aren't trying pulling more amps than your electrical system can provide, or the cheapest way would be to use a voltmeter that you can splice into your power and ground so you can monitor it. They sell some on Amazon for like $25 that will plug into your cigarette lighter or some audio companies sell this little digital one that you wire in with your power and ground but you'd have to install it yourself. Unless you have some tiny pitiful amp, you should not be pulling enough power to fry a voltage regulator if everything is installed correctly. Especially at 4ohms. I'm assuming you have a class D and they are usually extremely efficient at 4 ohms. Both the amps I have are at least 90% at 4 ohms efficient meaning that 90 percent of the power pulled is being sent to the subwoofers and the other 10 percent is lost as heat. Id start with cleaning up the amp ground and the grounds to your battery. Next if you haven't already id upgrade the battery wires as well. You can pick up a 4 gauge upgrade kit for super cheap.
