This amp is 2ohm stable, but if you use a dual sub setup and use both sets of output terminals it is automatically wired parallel at 2 ohms if you then have 2 subs that are dual voice coil and the voice coils of both are wired in parallel then the load become .5-1 ohm and the amp is unstable (solution) wire 2 dual voice coil subs individually one from each terminal, and then wire the voice coils in series rather than parallel

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts on either terminal when you drive the amp hard, you need to check the wiring feeding whichever line is dropping too low.

How do I connect my nitro 1000 watt amp to get thr most bass .i have two 15 vx kickers


If you have the Nitro bmw-482 running it at 2 ohms will give you the max output (its not 1ohm stable so don't run it that way). First run your two dvc speakers parallel (run both negative out puts together and both positive out puts together on each speaker). After this you should have 1 positive and 1 negative wire from each speaker (4 wires altogehter). This will give you a 1 ohm load which your amp can't handle, so you have to run the 4 wires in series to create a 2 ohm load. Now take the positive wire from 1 speaker and connect it to the negative wire from the opposite speaker. Thats how to run in series. Now you should have 1 positive wire from 1 speaker and 1 negative wire from the other speaker which is 2 ohm load. Your amp sould be bridgeable, so connect the positive wire into the correct terminal of your amp and the negative wire into the correct terminal of your amp according to where to bridge it (positive into left positive, negative into right negative) . That will give you a 2 ohm load bridged which is the most power you can get out of your amp 300 watts. Medium quality amps are over rated so you will never acheive the 1000 watts as advertised.

How do i wire a single sub at 4 ohms? which speaker terminals would i use?


If your single sub is a 4 ohm sub, you just connect + and - on the amp to the corresponding + and - terminals on the sub.
If it's a dual voice coil sub, it would have to be 2 ohms per voice coil or 8 ohms per voice coil to be able to achieve a 4 ohm load.

This will show you exactly how you'd need to do it:

How do I hook up my infinity 1600a at 2ohms with 2 4ohm speakers?


Placing the speakers next to each other face down, you will notice that the connection points run in sequence +- and +-. Now connect the - (negative) from the one speaker, to the + (positive) of the other speaker. Now connect the open + from the one speaker and the open - from the other speaker to your amp. Your amp should have a bridging indication. On the connection points of the amp, you should see a mark pointing to the first + and the last -. That will be your bridge and thus utilizing the full potential of your amplifier

When i turn the volume up my jl 1000/1 amp turns off then turns back on when the volume is low what can i do to fix this?


2 things, either your pushing too much power into the imputs (if using high inputs) and clipping the signal, or your running the ohms too low (lower then the amp can handle safely) by running multiple speakers of too low an ohm each. For example if your amp is 4 ohm stable and your running 2 4 ohm speakers in parallel that makes 2ohms and the amp can't handle a load that low. You can consult your manual and it will give you illistrations of wiring and ohm loads

Amp bass cuts out cuts back on


its a pretty simple principle...combine 2 speakers, and the ohm load gets cut in half. wire them in a series, and the ohm load doubles. for example, you have 2 subs that are 4 ohms a piece. if you combine both + and both - and put them to the amp, it cucts the load in half bringing it to 2 ohms. or, if you connect 1 + to the other speakers =, then run the remaining pair of wires to the amp, that doubles the load to 8 ohms. youll have to "double-ohm" it for dual voice coil subs. on each sub, you can do the same thing. either combine both + and both = into 1 wire to cut the rated load in half, or wire them in a series to double the load by connecting a + to the other coils =, and using the 2 remaining wires. once you have each sub wired the way you want it, then you can use the same rules when connecting multiple subs, by wiring in a series or parallel. it sounds confusing and its hard for me to put into works, but once you do it a few times its really easy. just remember the 1 rule...wire 2 coils parallel to cut the coils load in half, and wire it in a series to double it. hope it helps.

Speakers cut off when bass goes up


probably the amp going to safe or protect mode judging by the fact that you have 3 subs wired to it i would say it is not 1 ohm stable try disconnecting 1 sub and see if it still happens this will be running a 2 ohm load rather than 1 if it stops happening then you need to figure out a better wiring configuration that will work with your amp.

Cuts out at high volume.


and that's fine with the ohm load. But if you have them wired all together or in parrelel it changes the ohm load. You need to wire them all together in parreallel or in series to get the correct ohm load. Check the wiring diagram at www.the12volt.com to see what your options are. the mrp amps are at a 2 ohm load smallest stable so makesure they are wired above or right at

Amp Issues


1) Make sure a bridged load of no less than 4 ohms is applied.
2) make sure both the left & right channels are working.
