Bash 300S Digital Subwoofer Plate Amplifier 300W RMS
Bash 300S Digital Subwoofer Plate Amplifier 300W RMS is rated 4.3741 out of 5 by 147.
Rated 5 out of 5 by from Looks are DeceivingI bought this to replace the second plate amp I've had to install in my PSB 12" sub. The first two died and I was about to give up on this subwoofer. When I opened the box and saw how light this amp was I was a little concerned. The two previous amps were about 10-12 pounds. This one is light as a feather. The class D circuitry uses design instead of sheer bulk to make nice clean power. I figured I may as well upgrade the speaker while I had it apart so I installed an Eminence Lab 12 speaker and the PSB NEVER sounded this good. This little amp shakes the windows on movies yet sounds great with music as well. Very happy with this amp. The Eminence speaker isn't even working very hard with this amp and I may go with the bash 500 in the future but right now I'm going to go listen to some music...

Rated 4 out of 5 by from It works...for a whileThis is my fourth one in about 5 years. They work great, but then the fuses start to blow. Then they start to blow every time you put another one in. They are perfect for my set up, but they seem to only last until the one year warranty runs out. Not sure why they are failing, one is mounted in the wall (it lasted about 4 years) the other is mounted in a custom wooden case with ventilation that has lasted two years. The first one was not mounted anywhere and it lasted just over a year before failing. Use with the LFE connection exclusively hooked to a remote subwoofer that needed power.

Rated 5 out of 5 by from How it handles when things go terribly wrong.There are plenty of reviews here telling of what a solid offering this amp is. However I can tell you how it handles a catastrophic event. One fine day I was using it in a modest fashion listening to some music. I began to notice it playing totally distorted and then turning itself off after about two minutes. After several cycles of me turning it on and off the results were the same. Great I thought a year and a half use for over $150.00. After removing the amp and inspection/testing I could find nothing wrong with the amp. So next my attention was drawn to the speaker which actually should have been my first suspect. Testing of the speaker showed that my 8 Ohm speaker was now a 1.2 Ohm unit. This can lead to almost certain destruction of the amp. This amp handled it with grace and triggered its protection circuits in under two minutes saving itself. So the moral to this story is that this is a great amp when things are functioning properly and an even better one when things go terribly wrong.

Rated 1 out of 5 by from DissapointedIve had the amp for about 18 months with limited use. It was used mainly to power up 4 aura shakers installed under my couch. It suddenly stopped emitting power to my auras. It dropped in power drastically after using it for about 50 hours tops. Now im looking for something more reliable. Thats too bad, it did do the work at the beginning but failed me at the end.

Rated 5 out of 5 by from Outstanding PowerI purchased the Bash 300S digital Subwoofer Plate Amplifier to power my Episode In-Wall Dual 8 inch Woofers, and I couldn't be more pleased. It was easy to set-up, and the power on/standby feature is awesome. When I turn on my Pioneer VSX-1123 Receiver and 80 inch LCD, the Bash amp kicks on at the first request for low frequency. I've only had it for a couple of weeks, but thus far, I'm very pleased. My only complaint, I wish it came in an enclose or the manufacturer offered an enclose for sale.

Can you provide a description of the outputs and expected speaker ohm rating? Thank you

Asked by: Trango11
If you are referring to the subwoofer output, it is a red and black wire lead on the back side of the amplifier that are about 18" long. They have female disconnects crimped to them, but these can be cut off for other methods of connection. This amp is designed to deliver 300 watts RMS into a 4 ohm load.

Would it be possible if I just desoldering and swap the transformer from my rw12d 220-240v units to this one? Noted that the Yung amp could handle up to 240v but unfortunately this Bash seem more compatible. Otherwise, I may use external step down.

Asked by: DavePt
We do not recommend any such modifications to these amplifiers.

Is there any 220-240v model of Bash 300s?

Asked by: DavePt
We do not have a BASH amplifier that will accept a 220V input, but we do have a Yung that will, which you can see below.http://www.parts-express.com/yung-sd300-300w-class-d-subwoofer-plate-amplifier-module-no-boost--301-508

just bought this but can't find 110/ 220volt switch, which manual says it has? 

Asked by: robertt
This has no input voltage switch, it is 120VAC input only. Where are you seeing this in the manual?
