Ohms

[Dr. Winn]

What exactly is ohms, i know its a measurement of resistance, but if i get two p1 should i get 4 or 8 ohm?

it depends how you want to wire them.but normaly 8ohm is home audio and 4ohm is car audio

It depends on a few things. Normally it is cheaper to run subs with lower ohms because the amp will do higher wattage at lower ohms.

To answer that question we kind of need to know what amp you're going to be running. The best bet is to choose the subs you want (in this case 2 p1's) and find an amp you want to use to power it that matches the RMS ratings. Then when you find the amp, find out what ohm load it puts out the power you want and order your subs coil config based on that. If you got the 4 ohm subs you could wire them in parallel for a 2 ohm load, almost any amp should be able to handle this. If for SOME reason you buy an amp that can only handle a 4 ohm load, then you will need to get the 8 ohm subs and wire them in parallel.

this is helpful, but it looks like i have found cheaper p2 12s at 2ohms. so an amp that can handle 2 ohms?

You could run 2 d2 p2's in a series-parallel config for a 2 ohm load, or if you want you could run 2 d4 p2's in a parallel config for a 1 ohm load. It will probably be cheaper to find am amp that puts out the power you want at 1 ohm vs 2 ohms.

if you wire them together you can get a 2 ohm load or if you wire them sepreatly you can only do 1 or 4 ohms each

[Dr. Winn]

well i think ima jsut use my 800 mono amp at 2ohms and bridge the subs.

[chapo123]

those are dual voice coil right? if not ignore my above post lol
