I have an Alpine 12" Type-R 1242D subwoofer and I'm currently looking at an Alpine MRP M500 amplifier.

The sub puts out 500 watts RMS (dual voice coil, 4 ohms), and the amp puts out 500 watts at 2 ohms.

First, how do I bring the sub down to 2 ohms, like people say they do? Also, does the amp need to be more powerful? After measuring the power it can put out specifically, it came to around 600 watts. Is that too low or too high? I'm looking for a good, deep bass, mainly for rap, just for reference.

yeah it should work fine the amp is 500 rms at 2 ohm so i don't see why it would not and being alpine that is true rms. to bring the sub down to 2 ohm just hook both + togeather on the sub and do the same with the - and take the + end of the sub and run it to the + part of the amp and do the same with the - of the same and that should bring it down to 2 ohm since it is a mono block you should only have 1 channel and it should auto bridged it for you

Well that's awesome, thanks.

Could you link me to a good wiring kit?
