Bash 500S Digital Subwoofer Plate Amplifier 500W RMS
Bash 500S Digital Subwoofer Plate Amplifier 500W RMS is rated 4.2857 out of 5 by 77.
Rated 5 out of 5 by from Bash 500sNice plate amp. 1/4 turn on the power and the house shakes. Great price point and value. 300s is probably power enough for most sub applications in home theater, but all the headroom makes a person giddy. 500s if the neighbors aren't cool. 185 dollars. Definite loud power.

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!

Bash 500S Digital Subwoofer Plate Amplifier 500W RMS

My 500s just quit working this weekend after about 2 years of gentle, intermittent use.  Green light is on, but no sound coming out. I've checked the fuse, it appeared ok.  I swapped it with the provided spare anyway.  Any ideas on common failure parts?

What does "Fc"  represent in the Boost Tables? Are graphical representations of the boost curves available?

Asked by: James C

Has anyone tried this amp plate on an Epik Empire? Didn’t realize they went out of business, now I’m on a search to find an amp plate?

Asked by: Unclemel
As long as the woofer is 4 ohm this should work well. There is a good chance the enclosure will require modifications in order for this amplifier to fit properly.

Is this an open back or sealed back amp?  IE: Are the guts under a protective cover or exposed?

Asked by: Moike
The amplifier electronics are exposed, but the connections are all air tight so it does not require its own enclosure.

I have a Sunfire True Architectural Subwoofer the one with no passive and it has no amp.  I was wondering if this retro-fitted would be a suitable replacement?  I know the stock amp is rated at 1500 watts RMS but its some of Carvers voodoo magic. 

Asked by: The Shwortz
Yes this will work assuming the woofer is 4 ohm. Some commercial subwoofers have a very high rated impedance, so you will want to double check this first.
