Bash 300S Digital Subwoofer Plate Amplifier 300W RMS
Bash 300S Digital Subwoofer Plate Amplifier 300W RMS is rated 4.3724 out of 5 by 145.
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.

Rated 4 out of 5 by from 1st one was D.O.A.I recently purchased this Dash 300S to power my Digger 8 subwoofer build. The first one was D.O.A. I had to immediately turn around and order a second one and arrange a return of the first. The second one was $5 cheaper than the first due to a sale or promotion or coupon or something, but nontheless, the return was painless including a pre-paid shipping label from Parts Express. I returned the first amp while the second was ordered and just asked for a refund on the first. This was the quickest way for me to get a second amp in my hands. However, when my refund was processed, they refunded me the cheaper amount ($5 less) which is the second amp, not the first. But it was still a painless transaction and I didn't even bother to complain. The ease was worth the $5.00 SO I will give Parts Express 4 stars on the quick and painless return of my amp and refund of the "wrong" purchase.The second amp is working flawlessly so far. Look up the Digger 8 sub build if you are interested in seeing what this amp will do. It truly does rattle things 25 feet away from the sub, eventually had to turn it down because things were falling off of shelves in other rooms. I give the subwoofer designer their due credit for this coupled with this good amp. Either alone would not produce these results. LFE is truly off the hook.

Rated 4 out of 5 by from Great Little AmpBought this in the UK did not realize that it only works on 110v, but after getting a step down transformer in running this with my Dayton Audio 12" Sub, it does an amazing job. Tried using both the LFE input and RCA input and the LFE input works nicely by matching with my other speakers!

Bash 300S Digital Subwoofer Plate Amplifier 300W RMS

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

Can this be used on a KLIPSCH XW300D subwoofer?

Asked by: johnnnya
As long as the woofer is 4 ohm this will work fine. The cabinet will likely require modifications in order for the new amp to fit properly.
