Probably your power is too short, increase your gauge wire, and your ground wire of the amplifier has to be shortly as possible, and the positive has to be enough to support peak power, you can also put a big capacitor on the positive wire to give some more power while the bass peak.

Amp pops randomly and gets worse with my remote bass knob hooked up any ideas ?


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.

The protection modes in these units ****. Most new units have them. What I do is turn down settings on deck and turn up amp as much as possible. Then the protection won't turn on because you won't have to turn it up as high.

Amp is on, but sub wont produce any bass


Make sure the subwoofer is set to low frequency, make sure subwoofer and bass are enabled on the headdeck. Make sure the gain is turned up on the amp, make sure the rcas haven't come out of the back of the head deck.

Frequencies


Hello again ronnieyannon,

It's probably best to allow the amp that is powering the subs to control the frequencies going to the sub(s). I would not use the lpf on both the head unit and the amp in any case. The control settings are not completely precise and you could end up with a lot of tweaking between the units to get the sound you want. I'd send full range to the amp and with it playing something with a lot of bass, set the 401s to "LP", the crossover slope to near maximum, and then adjust the frequency until it sounded best to me. Starting on page 11 of your manual are the Rockford-Fosgate recommended adjustment procedures, including setting the gains and the filter frequency.

Those numbers for the lpf on your head unit sounds like it allows you to decrease (-24dB), as well as increase (+6dB) the bass at the specific frequencies of 50, 63, 80 and 100Hz. You probably don't want to decrease the bass boost for subs. And the 401s will allow a boost up to 12dB and is variable from 50-250Hz.

Hope this helps.

Low ohms light flashes and bass distorts at high volume


Sounds like you need to invest in a capacitor. Those are used when subs receive a bass spike. You just a need a 1 Farat Capacitor (1,000 watts) ran between the head unit and the amplfiier to fix your issue. Also, try reducing the volume gain to half gain and low pass frequency to half gain; this will increase your clarity and make your amp less hot. This may fix it without a capacitor. Also find out what amprage your alternator is. Your alternator may not be designed to run the amplifier. Most alternators are 200 amps now if they are gold plated.

Hope this helps
