Wiring for sub

[Setty7 10+ year member]

If my sub is a dual voice coil 4 ohm, and is wired in series should I look for an amp with a rms at 400-500 watts at 4 ohms or 2 ohms or at 1 ohm?

Series = 8 ohm

parallel = 2 ohm

I'd get an amp rated for 1 ohm so you have room to grow.

Look for a 2ohm amp that pushes RMS that is above your subs RMS @2ohm and adjust the gain so you don't blow it up.

You can wire a dual 4ohm sub one of two ways explained in the diagram below.

2ohm would be your choice. What sub do you have anyways?

I have a 12" kicker cvr rms of 400. im looking at an alpine mrp-m500 500 watts at 2 ohms is that good?

also how do you know what to chose on the amp 1 ohm 2 ohm 4 ohm? My sub is 4 ohm so how do you change it to 2 ohm?

The m500 is a nice amp but honestly you'll wanna get a 1 ohm amp for future upgrading, a 2 ohm amp locks you into a limited amounts of options. Look to the future and not the now, say you wanna upgrade all you'll need to do is buy another sub and build a box, if you buy the m500 now and want to upgrade you'll have to buy a new or another m500 along with the sub and box and thats alot more than im sure you'll want to spend.

Most websites will have an amp's rated power listed.

Here's how you wire a 4 ohm dvc sub to 2 ohms.
