How to reset a alpine mrp-m350 - Alpine MRP-M350 Car Audio Amplifier

SOURCE: i haw alpine mrp-m350 amplifier how many sub can i

Hook up the MRP-M350 to one 4-ohm sub, and you get 200 watts RMS; connect a second 4-ohm subwoofer and the power output increases to 350 watts! All that juice means that your subs won't just be loud, they'll sound clean and thumping.

From the plus(+) of the speaker output on the amplifier run a cable to the plus(+) on the voice coil of the first subwoofer then follow thru with the same cable to the plus(+) of the other subwoofer.
From the minus(-) of the speaker output on the amplifier, run a cale to the minus(-) of the first subwoofer then follow thru with the same cable to the minus(-) of the other subwoofer.
This will make your amplifier run @ 2OHMS and provide you with 350 Watt RMS which will work fine even if you run your subwooffers free air(without a box))
hope this helps

You dont specify the model or RMS power of the subwoofers so i am not sure if that power is RMS or maximum.
If it is RMS, then a BiG no would be the answer. Even though the MRP-M350 will drive the subwoofers and will give you a fair sound as well, it not drive both of them effectivley. After all it's only 350WATT (the amp)RMS trying to push a 2500 RMS (the subs) target, so do the maths, is that a fair fight?
hope this helps.

Check the ground wire. If you have a bad ground, you will not have any speaker output. The ground should be solidly connected to the vehicle chassis in a paint-free location. Check the live power wire as well, it should be connected directly to the battery. Then check the speaker leads to the amp. They should not be in contact with the vehicle chassis, or (at the input slots on the amp) with each other.
