Amp Help

I have a concept 2400a powering a newer xxx 12. The clipping light flashes on the amp if I put the gain only half way and the sub sounds way underpowered. Any suggestions??

Are you positive?

set your gain to the preout voltage on your head unit first

i wouldnt ignore it... maybe theres another issue wrong instead of that. you may blow the sub after while if you leave it half way... set the gain with a dmm, if it still sounds underpowered, maybe the box is too big or small, or the settings on the hu are not right.

Remember that there is no such thing as "half way up"

Gain is a function of the output from your headunit. Set the inputs on the amp to absolute 0 (counter-clockwise , or all the way down) put in your "Bass that Ate the Earth" music of your choice. Turn the head unit up about 3/4ths of the way. If it reads volume with numbers and lets say it goes to 35, then turn it to 30. Now go and turn up the sub amps input until the sub actually sounds like it is clipping. Not the "clipping" light as that is just a input voltage sensor.

Also assuming that the amplifier can actually make 2400 watts the current draw will Be somewhere around 280 amps! So you ,of course , wired this car with 1/0 gauge wire (power AND ground),and beefed up your battery ground as well as adding an extra battery...RIGHT???

Don't add a cap as that won't help under-current issues. Caps are GREAT! Just don't do what most people think they do //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Does opening the trunk make any difference? A little? or a LOT??? Boomzilla hit the nail on the head. DMM (volt meter) got to have it to figure out what is REALLY going on.
