I just installed the loc2sl. I have 2 10" subs hooked up to a 4000 watt amp when I hook both channels up it sounds weak so I unplug one rca & only 1 sub hits what do I hav 2 do 2 get both subs to hit

This is an indication that the MOSFETs are ok but the driver stages may have a problem. Get a schematic find the pre-amp stages and test the voltages levels there as compared to the schematic. I do believe that you will find the problem in the pre-driver pre-amp atages.

SOURCE: Stuck On Thermal Mode.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.


If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still remains in thermal protection, the amplifier likely has an internal fault and will need to be repaired.

you can **** yourself

SOURCE: amp cutting out when bass hits

make sure that all the connections to the power supply are tight. The protection circuit is doing this so that your amp do not burn up. The size of your amp also demand heavy wiring. Make sure you used the recommended size. Also you need to make sure that the battery and the alternator can keep up with its large demand. You may need an extra battery too. I know a single battery can deliver a lot of current, but a powerfull amp demands the current really fast, when the bass hits. You can use a large damping capacitor, they are extremely big, or you can add another battery. All these will also give your amp more thump, and make it operate at full efficiency. meaning even louder! If these do not solve the cutting out issue, you may have to turn down the gain down slightly. Every type of music do not deliver same amount of bass, hip hop music, and rap would require you to trim down the gain some. Bass is delivered at its best in moderation, too much and you end up with a rattle rather than solid bass. I have a 4,000 watts amp at home, I don't use it in my car. I got it rigged up as a house stereo. I bought it for a 100 bucks broken, and fixed it. I have worked with hundreds of car amps a before in a electronic shops, I also design small amps once in a while. I myself love those loud gadgets. Well hope it has been helfull. Goodluck.
