From the amount of time i spend in the ice section on CS i should really know this.

I'll tell u what i've got and u tell me what i can get!

AMP = PG 4x75RMS @ 4ohms
Comps = Inf Ref 90RMS @ 4ohms

I got 2 channels running my componant speakers.
This gives me 2 channels to spare (2x75RMS).

Now, i've read my amp's manual and it says:
4x75RMS
2x300RMS (2 chans bridged)

So from this i assume i've got 300RMS left to spare for the sub.

now what can i run?
in terms of:
Ohms, Voice Coils Single/Dual, and other stuff when it comes to subs.

Eg.
if i hook up a dual 2ohm voice coils to the amp as so:


The sub is rated at 250RMS.

will the two channels of my amp be under 2 or 4 ohm load?
will each of the two channels be under 2 or 4 ohm load?

i'll even scan the manual in.
to prove that it states 2x300RMS (2 chans bridged).

Cos even I thought this was way to high.

Output Power:
4 ohm Mono 300 x 2
2 ohm Per Ch. 150 x 4
4 ohm Per Ch. 75 x 4


Now you cant run your components in 4 ohm mono, and you dont have 2 ohm components. So unfortunatly with your setup you are only going to be able to have a 150RMS dual 4 ohm voice coil sub, which i think you will find extremly hard to find.

No because tell me how ur gonna run ur sub at 300RMS when you cant run your components off a single channel, its not possible. With that amp im sure you cant use 2 channels in stereo and the other 2 bridged.

Ok now its afternoon i can be clear

With this amp, your front channels should be set to highpass and your rears set to low pass.

Now im not totally sure on this cos i dont usually deal with anything bigger than 2 channel cos of the power side of it, but to get 300RMS bridged out of the rear channels i think both channels need to be bridged. Im probably wrong on that. If im not wrong it means you can only run a 150 - 200 RMS 4 ohm sub or a 150 RMS 4ohm DVC sub.

yes, two channels will need to be bridged to produce 300RMS.
i think the clue is in the name of the amp as well.

XS4600 (4 channels 600WRMS total)

NO what i meant was both sets of channels need to be bridged to get the 300RMS output. If you use the front for components and bridge the rear channel you should only get 150RMS at 4ohm, and thats why they recommend you use their XS104 for the rear channel as a sub.

go ask on the PG's forum, then see what it can and cant do
although it would suprise me if you could bridge a pair of channels into mono for the sub and leave the other two stereo for the comps...but i know there are a few amps about that can do this so

lol so u guys saying i can't run a sub?
as all channels will have to be either mono or stereo mode?
I can only have 4 stereo speakers, and 2 mono subs.
but i can have stereo speakers and a sub at the same time.

damn i only bought the amp so i can run a set of comps and a sub

You can run a sub but it could only be a 200RMS at 4 ohm max sub mate, and just set the rear crossover to Low pass.
