Need an amp for a SA E12 D2 (2 ohms)

[EC11]

Title says it all. Trying to keep this a budget build so what would a good amp be for the sub (only 1).

This is my daily driver so i'm trying to keep it close to the 400 rms rating of the sub. thanks in advance

We have the Precision Power i650.1 in stock and it's rated for 400W at 4 ohms. I have this amp in my car and it does a really good job, plus it's really small.

sorry, im new to this stuff, but the sub says 2 ohms, and the amp says 4 ohms. Does this matter? would it make a different rms figure? and how much is it?

The "D2" means dual 2 ohm voice coils. You can wire the sub to either 1 ohms or 4 ohms, depending on if it's parallel or series wiring. This doesn't change the power rating, but it makes an amplifier put out a different level of power in most cases. For example, the Precision Power i650.1 is rated for 400W at 4 ohms and 650W at 2 ohms.

Ohms is the resistance against current flow. Less ohms is less resistance against the flow, like water going through a hose. Bigger hose = lower resistance.

On the i650.1 this is how you should wire the sub to the amp:

Thank You! That was helpful. How much would the amp cost?
