![]() My gain is set to the head unit which is 2v. I checked the rca's one at a time, and I took a grinder to the chassis and installed my ground with a 14 mm bolt. I have trouble shot it for a while and can"t seem to figure out what is wrong with my setup. I've been on multiple sites and checked everything that is usually wrong with wiring. I have checked everything to see if i have it wired right, and everything is a go. If my bass hits hard then it will go into protect mode. If you're unsure of the best way to set up the gain or Punch Bass controls on your amplifier, we recommend you seek the assistance and advice of your local Rockford Fosgate dealer.My amp will play just fine at normal volumes, but when I turn it past 25 or more on the head unit it will play maybe for a bit depending on the bass on the song. (The same goes for the Punch Bass control.) If the gain is set too low, the amp will still make full power, but it might not sound as loud as it should, and you'll think you aren't getting much volume. If you have the gain set too high, the amp will make full power right away, and you'll have problems with distortion and "clipping". Essentially, by dialing-in the gain control you're telling the amp how much signal you're putting into it so the amplifier will reproduce the signal accurately. The gain adjustment (or control) is a level-matching control that adjusts the amplifier to work with the electronic piece(s) used before the amplifier. The most obvious thing to check is your Gain and Punch Bass control settings. Once it gets too hot, it shuts down for protection. The amplifier then "sees" a low impedance and tries to keep up with it, but heats up due to the extra power it's trying to make. Most common is the use of two 4-Ohm woofers wired together in parallel for a 2-Ohm load, then bridging the amplifier to that load - but the amp is designed for 4-Ohms, not 2-Ohms. In the event you are using a woofer (or a combination of woofers) that results in a load that's lower than what the amplifier manufacturer recommends, the amp may shut down to protect itself. If your power cabling is set up correctly, then you'll have better overall performance from your amplifier. Your positive power cable should be attached directly to the vehicle's battery using a high-quality battery post adapter, and must be fused within 18" of the battery itself. Your ground cable should be less than 18" long, the same exact size as the power cable, bolted directly to a solid, thick steel part of the chassis which is scraped clean of any paint or primer for best possible grounding. You should be using at least 8-gauge power and ground cable to power each amplifier you use. If your power or ground cables are too small for the amplifier you're using, you may also experience thermal shutdown because the amplifier isn't getting the power it needs to make the output you want. When it does, it is a warning sign to check the trouble before continuing to use the amplifier. Because our amplifiers can play into a direct short for longer periods of time than other amplifiers on the market (Rockford's proprietary technology called NOMAD), the problem may go unnoticed for some time before the amplifier shuts down completely to protect itself. When it does, it "sees" a condition that makes it get hot quickly and eventually shut down. If you have a speaker that is "blown" or is grounded to the chassis of the vehicle, the amplifier will still try to put power to it. Four of the most common are: Blown/grounded speaker(s), poor power and/or ground connections, too low an impedance (load), or Gain/Punch Bass control settings too high. There are several different reasons that an amplifier will get hot and shut down.
