If there's no sound at all from the subs and you know they are good, there's probably no output from the amp. It's either wired incorrectly or it is defective.
If there's some sound but just not loud enough, then either the amp is not getting enough of an input signal from your head unit, or the amp settings are not adjusted properly. Adjust the crossover and gains for the best output to subs. LP filter on, crossover frequency at about 80-100Hz, and gain to maximum without distortion when head unit volume is at about 3/4 maximum.
you've spent alot of money on **** by the sounds of it!!. you should only ever run multiple subs the same brand, power and resistance you can just connect any old subs to a system you need to wire them depending on the load that the amp needs to see. first thing is to try the amp/s on a individual sub to check your amps still work once done check the subs 1 by 1.
If there is no protection light on, be sure the input is on. Some head units need to be turned on manually (factory set to OFF).
Verify the subwoofers are wired properly.
A list of your components would help to solve your problem.
If it is new, it should still be under warranty - worst case scenario output transistor(s) blown, or power supply bad.
Turn the system off and disconnect the speakers. Turn the system on. If the amp still goes into protection mode with no speakers connected, then most likely the output transistors are bad. If the protection light is off, hook up one sub at a time until you find the one that is causing the problem
Audiobahn subs are not too powerful and they can not handle too much continuous RMS, be careful they will heat up and tear off the voice coils off ur subs. run about 100 - 150 RMS at 75 HZ to each sub and keep the gains at about 3/4 this way you will avoid blowing out your subs. It also depends on the amp? What kind of amp is it?
hi, sounds like u have a problem with the remotebass connection socket. the socket has little pins inside, check to see if they arent touching each other. also try not using the bass control, then try one sub at a time. u may find that one of the subs or sub spk wires cub be faulty. cheers.
