[QUOTE="Blackout67, post: 8893116, member: 683415"] Big three on a newer car isn't any different than and older one. You don't even have to replace the factory wires, just put the new ones over top. That's what I do. Maybe your factory headunit is grounding out somewhere causing it to malfunction. This could be where your issue lies cause it seems like you have it set up correctly. Could also be that your VRM just wasn't designed to take those up and down voltage spikes. They usually are designed to prevent that and aren't made in mind with a high power aftermarket audio system. Your DSP unit has a clip light and if you are setting it below clipping I can't see why that would be the reason. If I had to guess with the information that you've just given, it's likely an electrical issue up stream. Id check the voltage range on your VRM to make sure you aren't frying it with excessive jumps and falls in Voltage, next like I said earlier is also clean up all your grounds as well. If your amp or battery isn't making a solid connection to ground the voltage fluctuations will be more severe. You'll jump from 14v to below 13 from a small bass hit. If those don't work you might have to pull out your headunit and check out the wiring as best as you can.
