    I upgraded the ground to 2 gauge and the power to 0 gauge and new 150 amp alternator and new optima battery , Im wondering if it possible to run more then 13.8 volts to the amp ,and if so how would I go about this I think that there isn't enough volts I know there is a temp sensor and a volt sensor on this amp it's not over heating if I could find a way to bypass the volt sensor it would stay thumping at least I think so lol Wolf0303802000@yahoo.com

Can i run two 2ohm subs off a amp that is no lower than 2ohm stable


Yes you can, but they must be wired in series only. This will give you a 4 ohm load. If you wire them in parallel it will give you a 1 ohm load which may be too low for your amp to support.

I have 2 Maaudio HK4000 and i whant to bridge toghater? i have 2 pioneer subwoofers and i have it come down in 2ohm thogater. How can i bridge it?? mvh Leif


What are the ohms of the subs? Are they single or dual voice coils??? But FYI you can bridge the amps together, You have to use them separate one sub on each one. You can't run one sub on 2 amps.

My ma audio hk 898 will power on but will not push subs at all what can i do


Hello 76firebirdfo,

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.

Hope this helps.

Subs dont beat like they should


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.

My ma audio hk 4000 amp is powered on no sound coming thru subs amps brand new


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.

MA Audio HK4000D please help me ?


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

Is it enough


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?

 

Let me know if you wish. Otherwise
