When you say it is "pumping continuous bass," is the "bass" you refer to part of the program material from your audio source, is it a continuous low tone, or is it a random popping or thumping with no correlation to whatever program material is being played by your audio source?
If it is bass from the program material you are playing, please further explain why this is a problem.
If it is a continuous tone, you have an open feed line or a defective amplifier.
If it is a random popping or thumping, it can be either a bad feed line, a bad amplifier, or a partially-burnt speaker voice coil.
disconnect the speaker wires from the amp, and check for power. there is no resetting, other than simply turning the amp off and back on. if it powers up fine without the speaker/sub(s) connected, check your wiring and check the ohms with a meter. if you do not find a problem there(should read within 1ohm of how you wired it) then check for dc voltage coming out of the speaker terminals on the amp. should also check that the amp is getting good power and ground. if wiring and speaker(s) check out okay, then the amp is damaged. if you get dc voltage from the speaker terminals, the output transistors are shorted out and it needs to be repaired by a tech.
When you say that the amp "pops" are you referring to the sound that is coming out of the speakers? This is most likely the speakers "bottoming out", i.e. moving as much as they can, and then slapping against the back of the speaker frame. Adding the remote bass knob (presumably increasing the signal to the amplifier) would make the problem a bit worse, which explains why the popping increases after you add the bass knob.
You can try decreasing the gain on your amplifier and running the system at a moderate volume. If there's no popping occurring, you can be reasonably sure that the subs/speakers are just being over-driven.
first disconnect one wire at a time, making sure the power is off. then connect power and check to see if your speakers are making the popping sound. when you do your speakers, make sure you disconnect both positive and negitive of each speaker at one time. when your amp goes out of protect mode you will have found your suspect wire. then trace to the issue. it could be as simple as crossed over possitive and negitive wires
Check RCA,s at the back of the head deck, make sure sub is set to low bass frequency, make sure gain is turned up on the amp and head deck has subwoofer enabled and bass on. If you are powering speakers make sure the balance on the head deck is set to 0. Make sure it's wired up properly.
if your subwoofers are buzzing, its a VERY simple solution... your amp doesnt have a good enough ground. if you change your ground and the problem still exists, scosche makes a product for that which connects to your audio wires going into your amp.
Reset the amplifier using the manufacturers specified method. Usually this is just power down briefly and then back up. I usually pull the amp fuse and make sure all LED's on the amp go out. Wait 10 seconds, and then put the fuse back in.
If the LED comes back on when you reconnect power, without the HU being on, you've got a bad amp.
If the LED does not come back on after reset, then check for short circuits on the speaker leads. Still leaving everything off, from the amp terminals, remove both wires to a specific speaker and check for shorts.
Sounds like there could be a short somewhere. Check to make sure that there aren't any (exposed/bare) wires touching each other or if there is a bare spot of wire touching something metal. Check both ends of all the wires. A speaker wire may have come lose and is shorting out against the frame or some other place. Usually if it goes straight into protection mode or you're popping fuses you have a short somewhere. I assume the capacitor you installed is somewhere on the power line, which would be for helping with noise. You can also try disconnecting your amp from your stereo and see what happens but leave the speakers connected, you don't want to run the amp with out a load on it (the speakers). If your amp doesn't go into protection mode when the stereo is disconnected, then you have a problem with the stereo and not the amp, assuming you already checked for any possible shorts first.
It sounds like you may have a speaker wire shorted to ground. This could trigger the protection circuit. Check all wiring including the area behind the 6x9s to make sure that nothing is shorted to metal/ground. If you can't see any shorts to ground, use an ohm meter to check the wires.
Disconnect the wires from the amp and measure the resistance between the speaker wires and chassis ground. Ideally, they should show infinite resistance. If you read anything other than infinite resistance, trace all wiring to find the short.
