subwoofer problem
 

i just bought a car, and it had an audioban sub already in it (i dunno the model, silver in color) my problem is that on sum bass notes it start clipping, and @ high volumes, what can i do to stop this. its on a rockford fosgate amp and its in a box

any suggestions?

specify the specs of both the sub and amp. U most probably need a capacitor

just took a part my sub box, i have an audiobahn alum12q and a rockford fosgate punch amp 250 rms @ 4ohms and the sub can apparently handle 1000W rms, i dunno if the set up is 2 or 4 ohms, but the clipping is friken annoying

sounds like you might be clipping the amp to make the sub do it's thing...

basically, yer pumping shyt into it = shyt is gonna come out of it

i din reely catch that...could you possibly elaborate...or tell me what i need to do to fix it?

thx

your amp will have a gain on it, that matches the output from the head unit, its not a volume adjustment

when the gain is properly matched to the head unit output the signal is clean (note: sine waves) but when you want more bass, some people turn up the gain figuring they can make it louder, but all it does is try and produce more wattage, from something that can't electronically produce, so the output becomes all distorted, and if you looked at it on an oscilliscope you would see it doens't look pretty, and can actually hurt the sub because it doens't allow 100% cooling with a smooth linear up/down motion

^ very nicely said.

that means to turn down the gain.
