[QUOTE="paulmarsh1222, post: 8490531, member: 669469"] The amp is rated for 450rms at a battery voltage of 14.4 volts. If you have a stock battery you only get 13.8. Manufacturers use 14.4 to boost their amp ratings a bit that's why I was giving you lower more realistic numbers. Since I'm not there and I can't see your wiring I can only assume the amp is getting hot because it is either drawing too much power, the ohms are wrong and are too low, and even if you were only pulling the max rms at the lowest allowed ohm bridged, the amp will naturally run hot. You can't prevent that. That's why when you use an amp to its max potential usually you must cool them down with external fans. What are the subs switched at? 2 or 8 ohm? Also, post a pic of your wiring. When you check the gain with the dmm, you're going to want to turn your headunit up to 3/4 of the way and turn the gain up until you get 56.5. This will give you about 800 watts rms if you successfully bridge the amp at 4 ohms. I know it says it can do 900 but like I said that's at 14.4 volts which is exaggerated so you want to be conservative and not fry an amp like yours. They're tough but overheating is a killer that can be avoided. [/QUOTE]
