When using this type of amplifier, especially to run subwoofers, you need to use a capacitor of at least 1F in value across the power input. Large capacitors counteract the effect of voltage drops caused by audio program elements such as heavy kick drum beats or other low-frequency spurious elements, and can save your car alternator from being damaged as well.

No you don't. You'll fry the amp. You need a low frequency processor to strip the mid and hi frequencies out of the signal applied to the subs or you'll have a full frequency sub that will sound cruddy. If your amp outputs 8 ohms the you'll have to wire 2 speakers in series or poof goes the amp. If the amp is only 16 ohms then you're out of luck unless you have 2 more speakers to connect in series to the 2 you aleady have.

If there is no reset button behind the faceplate (usually small and either black or sometimes red ) Press it and hold it down with the tip of an ink pin for at least ten seconds , when you release it it should have reset your unit. If you don't see the reset button , just disconnect the power wire (red) and 12 volt constant power (yellow) for about 10 seconds as well. That should do it ! Good luck !
