Its really a shame you can't bridge the channels on the XPA-5 Gen 2's, that would be ideal for my situation.

For a passive sub outdoors I would pick up a two-channel pro amp and bridge it.

Anybody else have any thoughts or longer term experiences driving a sub with one channel of the XPA-5?
That's an 8ohm sub. You'll only be getting 200W out of the XPA-5 at 8ohms. Since you already have it there's no harm in trying it with what you already have. Slowly ramp up the volume and see how well it handles the load.

The amp will go in to protect mode if it can't handle the current draw. If it does you know you'll definitely need to get anot her, more powerful, amp. Behringer makes some decent quality amps that are relatively inexpensive that should have more than enough power for your sub. Pro amps are loud so plan on swapping out the fans of you keep them near your listening environment.

+1. Doesn't hurt to just try and see what happens. If you cannot keep your hand on top the amp it's probably too hot (test and check before having the amp shut down at a party).

For a cheap amp, Behringer iNuke series. My choice would be one of the lower-end Crown XLS series amplifiers.

There's actually a slightly used Crown XLS1000 for sale locally here but I'm hoping to find an amp that will provide a high pass filter for my satellite speakers. Looks like this amp only has a pass through for satellites.

I have always used an external crossover before the amps. Inexpensive options are a miniDSP board for about $100 or a dbx XS223 analog unit for around $200. Are you using the Crown to drive subs and satellites? They have a crossover for that, or you can figure them as LPF or HPF. I don;t think they have a crossover output you could use to drive a second amplifier, however (not real sure, you can download the manual online). I am not very familiar with Behringer DSP capabilities.

Some test results here:

Most are overkill though. Majority of people like the INUKE from behringer and for the price they are hard to beat (assuming price is a driving factor for you). I wouldn't consider anything less than the 6000 (with dsp if this is for subwoofers). Works with 4 or 8 ohms per channel. Single channel usage will allow for more power than stereo even though you cannot bridge the amplifier.

You can pick up an amp that you can actually bridge, but will more than likely pay more money per watt than running the inuke with a single channel.

Crest CC4000 or CC5500 are also good options along with the Crown XLS series.

This is pretty off topic now though so if you link to a new thread we can continue discussion.
