Bash 500S Digital Subwoofer Plate Amplifier 500W RMS
Bash 500S Digital Subwoofer Plate Amplifier 500W RMS is rated 4.2763 out of 5 by 76.
Rated 3 out of 5 by from Meh. Limiter circuit limits sound quality too.Lots of power, but you can hear the current limiter working, even at moderate levels. Transient punch is reduced to transient smoosh. This is compared to running the same sub on an old Adcom GFA-555. That may not sound like a fair comparison, but I am referring to the sound at moderate levels that should not tax either amp.Also, after about 18 months, mine blew a pair of mosfet switchers in the power supply. I've repaired it, simply by replacing them, but in the process, I observed that there is very little overkill in this design. It's components are running near their limits. The capacitors are pretty cheap. Very nice circuit board though.Ultimately, this is built just like a mid-range computer power supply.Meh.

Rated 5 out of 5 by from Polk Audio PSW 1200I have a Polk Audio PSW 1200 which is the biggest home audio powered sub they ever made. Dual 12" subs weighing in at 110 lbs. I bought this thing new and had it now for about 10 yrs. The amp went out in it and Polk has no replacements so I had it repaired which lasted about a yr. Researching a comparable replacement amp that could push two 12" s I took a chance on this amp. This amp is slightly smaller than the original Polk amp so I made a plate out of wood and mounted this amp into it. With this amp it put this sub to a new level. The amount bass this sub puts out now far exceeds the original set up from Polk. They cut themselves short by under powering the amp they put into it. I mainly use my system for home theater and it's like a new piece of equipment. Last night we watched Polar Express (yes, it's Christmas eve) and when the train came down the road I thought it was coming through my house. Very impressed and glad I resurrected an old friend by purchasing the Bash 500. Awesome job!!! My neighbors may not be as happy as I am though.

Rated 5 out of 5 by from Excellent!For my application this amp seemed to be my best choice for overall diversity. I run a coax from LFE on a Technics 5.1 receiver, sounds great so far. It's home to a custom 3.75 CuFt. Ported box(including bracing and internal weighting#. The box also utilizes a parts express 6"x17" flared precision port. Speaker is a MITEK 15" DVC#2 ohm per vc#. The amp is perfect for versatility, if down the road I want to scrap the current application I can use this amp for something else. VERY HIGH POWER and clean too. Zero distortion! Auto turn off works fine with the receiver I am using. Seems to be an efficient and cost effective design. No need to be concerned about the open design with exposed circuitry, you do not need to build a separate enclosure, it is made this way on purpose to help keep the amp cool. The exposed circuitry is extremely ridged, I would not recommend creating your own enclosure unless you use some sort of project box with internal fan#which would only draw dust into the circuit boards and heat sinks). If I hear a bass head driving down the street, I can easily break his windows with my bass from the house with this amp. PERFECT for music and home theatre applications.

Rated 5 out of 5 by from Bash 500 Watt Subwoofer Module and Eminence SubwooferI had a Boston Acoustic 300 watt subwoofer which is down firing and the module went out. I ordered the Bash 500w subwoofer module and the Eminence LaB 12, 12" Subwoofer. I built a front facing cabinet. 1.92 Cubic ft. with 2, 11/2 ports extending 9" into the Cabinet. I have the volume on the Bash set at less than half way. Watching Live and Let Die and the movie Olympus Has Fallen, it is awesome. It felt like my room was being disconnected from my house. If you want to find out what subterranean feels like this is an awesome pair. Other woofers might work just as well with the Bash 500 but I am partial to Eminence. I have been using them ever since the 70's and they stand the test of time and take everything you throw at them. I'm also using a Marantz AV7701 Preamp & Parasound A51

Rated 5 out of 5 by from Replacing the plate amp on my Epik Conquest subwooferThis could not have been easier: the overall and cutout dimensions were identical and the screw patterns matched perfectly. It took about 10 minutes to swap out the old and get the new one going. The new amp works exactly as advertised. Really pleased with this purchase. Thank you Parts Express!

Rated 5 out of 5 by from Bash AmpI've only had this plate amp for a week but I have found no complaints. Good features and strong output. Doesn't get very hot. Auto on feature works great with no thump or pops.

Bash 500S Digital Subwoofer Plate Amplifier 500W RMS

Is it 500w per channel if using 2 subwoofers?

Asked by: T Mohn
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?
Asked by: GrandPixel
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 ?

Asked by: fjcruiser
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?
Asked by: Big Jim
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.
Asked by: Jerry1958
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?

Asked by: Fixer
Yes, all you have to do is use the LFE input to do this.
