Powerbass xa900

[Jason Myjak]

I own a xa900 class d mono amp..It is mono but 2 channels on it,basically 300 watts @ 4 ohms,600 watts @2 ohms, and 900 watts@ 1 ohm..My question is I've had amp for awhile, How do I wire 2 sub's down to 2 ohms or 1 ohms, since it is a 1 channel how do I use both channels correctly for amps full potential @ 1800 watts.. This is my 1st time using kind of amp,

You have a mono a amp meaning it only has one channel.

It's internally wired in parallel. It has two sets of speaker inputs for wiring ease only.

What are your subs, SVC or DVC? What ohm are they?

Powerbass 10" dual 4 ohm voice coil..right now each sub is wired directly to both inputs..So I can rewire them to drop down to 2 or 1 ohms???

This should help.

Also I don't know the power handling of your subs. But yes DVC 4 ohm can be wired down to 1 ohm

So I went onto site, when calculated, do I input 1 or 2 speakers, and I'm obviously gonna use both input terminals on amp??

You could run one woofer to each "channel" which is not a channel lol. Then just run your jumpers.

Why is it obvious? If you wire one 4 ohm dual voice coil in parallel, and then wire it to the amp as one connection the amp see 2ohm load.

If you wire the same 4ohm dual voice coil sub on both of the speaker connections on the amp it still sees a 2ohm load.

It's the same either way just ease of wiring.
