Get a cap, your alternator isn't supplying enpugh voltage fast enough.
Do you mean the sub cuts out and stops playing (clips) or the amp cuts out on it?

He's got 1 sub and a 300 watt amp. He doesn't need a cap. It doesn't sound like clipping if he's got to turn it down to zero. What are your gains set at? Do you have a protection light? I'd lower the gains on the amp, and see if that changes anything.

sounds about right check the gains on the amp heres a process i heard somewhere, correct me if im wrong: Turn your amps gain all the way low, (higher voltage), then turn your head unit to 3/4 full volume, finally adjust your amps gain up (lower voltage) till its loud
or the easier way is find out your HU preamp Voltage and match the gain to that.
-finally if that doesn't work check all wiring, incuding the wires from amp to sub, inside box as well!
PS: (how do you have your sub wired to the amp)

This is my head unit...Dead Link Removed
If I'm correct it says 4V pre-amp output, how do I know what to set my gain at. I looked at my amp and it has a nob but no numbers to adjust gain.
It has a another nob for bass boost from 0dB to 12dB, what do you reccomend I put it to?
Alos, there is a switch for LPF, HPF, or off. I know its a filter, but that does it filter and what should I switch it to?
Thanks
Tim

Set the x-over to low pass filter, I think your gain should be set around a quarter. Set the bass boost until you like the sound.

I've heard that about what they said above with the gains and head-unit. But on my truck, if I do that I have to have the HU on full blast to get the bass hitting hard.
I use an MTX 2300x amp for my subs bridged so I have both gains up all the way along with the both eq's slightly down and both x-overs on the amp set to match the x-overs on my other amp for mids.
I know what the gains are for, but why do some people usually have them barely turned up? Is it just the kind of amp I'm using? Everyone I know w/ a system has their gains set to full as thats the really only way to have the bass hit hard.
1 thing I don't know is do the gains help prevent amps from over heating by controlling the power of the amp?

It's 9:30pm where I live, I'm gonna go get my flashlight and mess with my amps gains, see how it comes out, I've had them on full for 3yrs but I'll try to lower them and mess w/ my HU scince it can adjust my whole system. I'll see what happens, damn this is one borring night, just about everyone at my college (very small private college) is doing work or just chilling, what a night

The gain knob is not a volume control!!! It is to adjust the voltage correctly between your head unit and amplifier
i dont know if this was mentioned and dont care to read the other posts this time of the morning but here is my idea.....
your speakers are wired for too low of an impendence, this will usually play, but wont sustain high amounts of power, ive done this on occasion and it sounds like what is happening to you, take your amp and set it on top of the sub box or some place you can see it when you are in the drivers seat looking back...make sure you can see the green light and red light or whatever your amp uses to show the amp is working or not working....
turn the system on and turn it up loud.....if you turn it up loud and the protection light comes on then you have it wired incorrectly, rewire your subs (im guessing you probably have it bridged and its presenting too small of a load)
