Better Bass

My current setup needs tweeking. I have 2 mm124, punch bd500.1, in a probox with .8 cub ft for each sub all in a reg cab 02 F-150. My goal is hard hitting, quick responsive, puchy bass. Is this possible with my current setup? I hear a lot of clipping and bottoming out of my subs. I think there are air leaks from my box. Is there a way to seal my box like fort knox?

    The problem may be youre underpowering those subs. The MM124 handles 500 watts and youre giving each 250. So in order to get good bass youve probably got your gain set too high and so youre amp is being pushed into clipping but since its clipping at 250 watts, its not hurting your subs, just your ears.

    You need to get another amp. Youre gonna need something along the lines of 900-1000 watt Class D amp. This Coustic would be a much better match to your subs or this MTX.

    You could also get something like this 4 channel MTX and bridge both front and rear.

    if you're hearing the subs bottom out, and you're running them in a sealed box, your gain is crazy high. i don't know how much bass you want, but the most you'll safely get from your subs will be found by doing this. here "safe" means that your subs will live longer.

    the easiest way i've found to seal a box is something like liquid nails - run a bead along each inside edge, then smooth it out with your finger, making sure it's all nice and pretty looking (cause this'll make it seal well, yah?). you very well may have leaks, so check by listening all around the box when the subs are on a very low (10-20 Hz) sine wave. then, you won't hear sound from the sub, but air leaks will be painfully obvious. if you have leaks around the sub itself, it may help to mount it on weather stripping (found in the windows section of your local hardware store). just stick the stripping around the cutout hole and mount the sub right on top of that.

    you should probably do it the other way round... set the remote gain all the way up, then tune according to that link using the gain on your amp. this way, you can turn the remote gain as you wish without fear of harming the subs; you can also turn it down at night, for different songs, etc.

    and try www.secondskinaudio.com for dampening.
