Can i hook this amp to a 2 channle out put stereo?

If the subs you have are 2 ohm DVCs, that usually means each voice coil is 2 ohms. Putting the DVCs in parallel will make the sub 1 ohm, which is beyond the capability of the amp (which is only stable down to 2 ohms per channel). Putting each subs DVCs in series (for a total of 4 ohms per channel) will at least allow the amp to operate properly, even though you will not be able to maximize the output power.

Check your ground

Look on amp for a dial or button that says GAIN or LEVEL try adjusting

you have 2 0r 4 channles put your +wire in the first channel and your - wire in the last channel -with both speakers wired together

just press menu the go 2 channel edit and away u go put ur codes

Pretty Straight Forward get a 8 or 4 gauge amp wiring kit.

Run your hot wire to the +12V from the battery make sure to install the supplied inline fuse near the battery don't connect to the battery until installation is complete.

Run the REM to your stereo power ant. Wire. if available.

Run the GND to Metal Chassis Ground keep it as short as possible.

Run the RCA Cable from the back of the Stereo to the RCA Inputs or Low Level on the amp.

This amp is 2 Ohm Stereo Stable which means you can connect 2 (4 ohm) speakers in parallel to each channel or 1 (4 ohm) speaker on each channel or you can connect 1 (4 ohm) Speaker in bridged mode.

There are other speaker configurations you could use but you cannot drop the load below 2 Ohm in stereo mode and no lower than 4 ohm in bridged mode.

Hope this helps

Hi,

On teh back there's a mode switch, you can put this one on stereo. Then you have a normal stereo amp.

With your multimeter set to DC volts, the black meter probe on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red probe alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

Let me know if you have any other questions.

Hook up the battery, (the negative post) and then put the fuse in. This is the best choice because if you put in the fuse and then put the negative post back in and the wires slip when putting in the negative post, the fuse might blow due to the sparks. You will then need to get another fuse, which also mean sending more money.

YES ! This is usually ok, the speaker cabinet should contain a high pass filter or crossover on the tweeter to decouple it from the low frequency signals. My Linn Index speakers are wired like this.
