Bash 500S Digital Subwoofer Plate Amplifier 500W RMS
Is it 500w per channel if using 2 subwoofers?
That would mostly depend on how you have the sub-woofers wired. If you have two 8 ohm subs and you wire them in parallel to make a total load of 4 ohms, this amp could drive 500 watts RMS into the system in a mono setup. I believe this is a mono plate amp, so no stereo amplification (you could get two plate amps, one for each channel).If you have two 4 ohm subs, you *could* wire them in parallel to make a total 2 ohm load to get more power out of the amp, but this could be risky because this amp might not be able to remain stable driving a load that low. Remember 2 ohms would be the nominal impedance rating, it would most likely be lower than that at certain frequencies.

How can a 6 lb. amplifer output a real 500w?
This amplifier does not seem to have much of a power supply / transformer, and weighs only 6 lb. How can it output a real 500w of power?
it uses a PWM (pulse width modulated) power supply they are small and light. and it DOES put out 500W rms.

I have a push / pull 2 sub, sealed enclosure. one of the subs needs to be wired out of phase. So is this amp able to be wired to 2 subs or only 1 ?
You can wire as many subs as you want. Since you're just wiring the two subs out of phase they can be wired to the same channel just make sure the impedance matches what the plate amp can handle. More than likely you'll be sending a 16 ohm, 8 ohm, or 4 ohm load depending on if the drivers you're using are 2, 4, or 8, ohm.

Is this 3-ohm stable?
I have a spare JL Audio 8W7, which is a single 3-ohm sub, and figured I'd drive it with a plate amp on my computer system. Will this amp be okay?
That driver was designed for mobile applications where speakers are connected in series and parallel, where amps are often spec'd at 2 and 4 ohms. The BASH will work fine if you do not use dramatic boosting. That's where you will create high demands on the amp at very low impedances. From the JL specs, the driver will perform best in a ported enclosure if you want the lowest possible frequency response and require little amp boost tuning.

Is this possible?
I'm planning on upgrading my home theater system and I would like to add a subwoofer to each speaker channel. I want to install each speaker system into the wall.I saw the back of this amplifier and it seems that I could tie into the A/C power connection. The power will come internally from the wall and I do not want a power cord sticking out of the unit into the room.It is a 7.1 system. On stereo applications as just listening to music I realize it would not matter because the stereo sound is spread across the speakers but in movie applications where there are actually 7 independent channels that could independently have low frequency effects I would like to hear them separated.Some people say that low frequencies are non-directional but I can tell where my subwoofers are located in the room. I want each channel to be able to duplicate the low frequencies delivered to it rather than all low frequency effects delivered to one subwoofer channel.So is it possible that this amp could work for what I want to do?I need the controls to face the room but I need the A/C input to be inside the wall. Also I am concerned about heat. I do not want heat to build up inside the wall.Could this unit work for what I want to do? Or is what I am trying to do unfeasible?Thanks.
OK, Lets try to take this 1 step at a time.I think you are trying to stay you want either 2 or 7 sub channels because you feel your current set up is directional. While this is entirely possible it might be a tad overkill and wind up being quite expensive but it can be done.So to will this amp work for you intended purpose. Yes and No.Yes it will power subs but it is a mono amp. Unless you wanted all the low frequency data to be mono at each source. But No it is not the best amp for this purpose as it really is not designed for in wall use and you would need to modify the power port to move it to the other side. While this is doable I would not recommend it for the novice.If you were planning on 7 sub-woofers off 1 amp you would need to make sure you have the correct final ohm load and polarity on them. Not even talking about the possible enclosures and wiring.If you really want a slew of sub-woofers I would recommend a rack mountable pro amp like below to power your idea. Just need to figure out what sub-woofers you would want to use to determine the power required.

Is it possible to completely bypass the low pass crossover of this amp for use with an external crossover?
Yes, all you have to do is use the LFE input to do this.
