Ndnkobra Posted February 14, 2010 Report Share Posted February 14, 2010 Hey guys, i just went outside to put my subs back in, but i decided to check my gains to see how well they were the first time. I didnt use a multimeter the first time, and so i went outside this time and stuck the leads into the speaker outputs, threw a 50hz cd test tone from realmofexcursion into the deck, set my volume up to 30/40 and set all equalizers to 0. Now, i need 1200 watts @ 1ohm, which is about 34.6V. well...as soon as the test tone started playing, i saw my DMM jump to 54V. I nearly hit my head on the siding of my car when i saw that, and i immediatlely set the gains down to about 34.8V. I didnt know i was clipping that amp like a toe nail. I'm a little upset about it because 1. I thought i wasnt beating hard enough the first time, 2. i KNEW i heard something weird when i had my subs play, it didnt sound normal and 3. Now my system wont be as loud as it was before . I guess this explains why my amp killed the stock battery the first time, things should be better now. I'm surprised my subs took that much power like champions, they're still fine too. But for any input, my subs wont be as loud as they were before, correct? And any suggestions on how to make it louder without destroying my amp like i could've potentially done, and hopefully i was checking the gains right.

Toady Posted February 15, 2010 Report Share Posted February 15, 2010 having the gain higher just reaches the full potential of the amp quicker, which means anything over full potential is gonna clip. If you set the gains right on the subs, adjust the filter, and balance out your mids and highs, you can probably be able to turn the head-unit up more which means that you can use more amp power and get louder than previous results. Look at it this way, you wont be damaging your amp anymore, and you can always purchase things to get louder. Better electrical, Better wire, Eq's, Epicenters, Different Box, Etc.
