Bash 500S Digital Subwoofer Plate Amplifier 500W RMS
Bash 500S Digital Subwoofer Plate Amplifier 500W RMS is rated 4.2375 out of 5 by 80.
Rated 1 out of 5 by from This amp is junk.This amp was installed as a replacement to the original amp that blew on a JBL 15 subwoofer. It lasted only 4 or 5 hours of use while listening to music at about 80 dB (moderate sound level).

Rated 5 out of 5 by from Very user friendly!I bought this amp for the Knock-Down MDF 1.5 cu. ft. Subwoofer Cabinet & 12" Infinity sub I already had. Wow! This thing packs a punch!

Rated 3 out of 5 by from SQ far from good but it works and does rated powerOwned for over a year now and it's still working. Had to replace one of the fuses, no idea why it blew. Upgraded the speaker wire and terminals going onto the board. I've used it on a few different subs/enclosures and it is loud and definitely does rated power, if not a tad bit more than rated power.The limiter circuit, as a previous reviewer stated, needs some work, or needs removed completely. It absolutely kills every bit of sound quality this amp may have. The limiter is constantly adjusting itself not only at high volumes but medium volumes as well. This leaves me constantly adjusting the "volume" knob for different media, switching between movies/music etc. The limiter is not as noticeable on movies, but music is another story. This amp is not for music. The limiter also gives the amp just a plain muddy sound. It's not tight, nor accurate, nor even sounding, no matter the enclosure type. I've tried sealed, ported, and T-line boxes, and even the sealed enclosure sounded muddy.The 6dB slope crossover leaves MUCH to be desired. Even with the crossover set at 50hz, voices and midbass still come through, how much they come through depends on the enclosure and my T-line box is what brought me to notice how weak the crossover is. With my T-line, it's almost as if the crossover isn't even there. And yes the LFE switch is switched to crossover so it's not the LFE switch, and there is a difference between LFE and crossover, so it's just a really really weak crossover. A selectable 6dB/12dB/18dB/24dB switch is needed and would be perfect.I dabble between home and car audio and consider myself an "audiophile"/SQ kind of guy, and usually home audio manufacturers have the sound quality enthusiast in mind. Not the case with this amp. My car subwoofer amplifier is leaps and bounds ahead of this amp in terms of sound quality and it puts this amp to shame. It has selectable 12/18/24dB crossover switch (yeah, they didn't even bother with the useless 6dB crossover), adjustable bass EQ frequency and level, a high damping factor, and no darn stupid clip limiter, which makes for a darn good sounding amplifier. Take notes, BASH engineers.I gave this amp 3 stars because it still works and it does rated power. Those are the only good things about this amp. I suppose it looks nice as well. The build quality is meh. The sound is meh. The power is good.

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.

Does the unit come stock with any base boost, or is it necessary to change the resistors values to achieve this?

Asked by: donkt88
Unfortunately, we do not stock the amplifier with the bass boost already in place, you would have to make the modifications.
