Bash 300S Digital Subwoofer Plate Amplifier 300W RMS
Bash 300S Digital Subwoofer Plate Amplifier 300W RMS is rated 4.3867 out of 5 by 150.
Rated 5 out of 5 by from Just about Perfect Fit for a Boston VR2000Have had the amp repaired in my Boston VR2000 (late 1990's) and now having trouble finding a place to fix so decided to just replace. Physical size was an issue cause as shown in the photo, the amp and control unit are two different plates, so the Bash 300 is a 99% perfect fit. I had to enlarge the opening just a little on the bottom to get it to fit. The width is a bit too big so unable to attach with side screws and had to seal the left side but otherwise fits and works great! Had to cut and splice the speaker terminals from the original amp due to the size of terminals on the speaker, but that was easy.

Rated 5 out of 5 by from Great replacement ampI purchased this amp to replace the blown amp of my Infinity PS-12 sub. (The original amp for the PS-12 is sealed inside the box and very poor ventilation so it overheated.) This amp exceeded my expectations completely, plus because it is a plate outside the box, heat dissipates quickly. Hopefully this amp lasts for years to come!

Rated 5 out of 5 by from Works as advertisedReplaced a JBL PB12 with this. I have two. This one sounds better now with the new amp. Stock Amp used to make a lot of noises even in standby. Its a known issue with that model number. I am sure then other one will fail eventually so this will be the replacement I go with again. Had to cut the box and patch the hole where the stock amp sat. Not a hard fix at all.

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.

I have a dual VC 15" subwoofer, 4 ohms each VC. Will this amp handles a two ohm load if I parallel the voice coils?

Asked by: albee
This amplifier is only stable to 4 ohms. A dual 4 ohm would need to be wired in series to use this amplifier on it.

Ok so will it work in EU (240v) ? as I see different fuses according to voltage in specs above. Correct me if I am wrong. Would like to change my blown JBL es150 amp as it has the same rms values...

I live in France and who i can connect it to 220v

Asked by: Riri
This will require a step down transformer in order to work on 220 V. I would recommend a 500 watt model, minimum.

Stupid questions: is this a mono subwoofer amp? so left and right inputs, but only a single speaker output. 2) can it be adapted to 220 volts by moving jumpers?

Asked by: meshplate
Yes this is a mono amplifier. Unfortunately it is only rated for a 110VAC input.
