Review: Great little unit - The power of the unit and its settings are great. I didn't flush mount it as I was using it to.power an existing subwoofer that's self-contained. It works great.
Review: Good replacement for Polk PSW110 - I bought the SA 100 to replace a dead amplifier plate in my Polk PSW110. It seems to be better built than the original; The original weighed about a pound this weighs about 8 pounds and is more adjustable than the original. Sounds much better in my home theater system than the original did, for sure an upgrade. Did not fit the original speaker box ; I had to widen the box about an inch; Then make a spacer from a 1x12 so that the SA100 would fit in the speaker box without hitting the baffle that is at the top of the speaker box. So far I am happy with this product the upgrade alone was worth the effort.

## Questions & Answers

**Q: Can I convert my passive subwoofer into active using this amp?**
A: Yes you certainly can.  This is a great amp with lots of inputs.  I used it to replace a burnt out amp in my Cambridge SoundWorks sub woofer.  Any passive subwoofer can be adapted to active with this amp.  It has a mounting flange and so you just cut a hole in the back or side of the box to fir the amp, connect to the speaker inside the box with the leads coming out of the back of the amp, screw the amp to the box through the holes in the flange and then connect to your exiting speaker wires or direct from the sub-out on the main amp and power it up.

**Q: Can i use this amp for a 2ohm subwoofer**
A: I'm not sure. You may want to contact the manufacturer, but it's been a great amp.

**Q: is this subwoofer plate amp available with 220VAC main input supply?**
A: hi sorry for the late delay, but this subwoofer plate amp is not available with 220 VAC main input supply.  you need to buy 110VAC to 220VAC convertor based on the correct wattage specified for this amplifer.

**Q: Can this handle 4 AuraSound AST-2B-4 Pro Bass Shakers without any issues?  I've seen this bundled with them (some even in 4 packs).**
A: So did anyone used this amp with 4 Aurasound AST-2B-4 Pro Bass Shakers? Do they go well?

### ⭐⭐⭐⭐⭐ Very punchy amp. Good price. Easy install.
*by M***E on September 16, 2019*

I purchased this to breathe life into a BIC F-12 subwoofer who’s plate amp had failed The BIC subwoofer has a 12 inch driver. I was outside of the warranty. So I had nothing to lose and when I found this product at $109 .....it was much less than replacing the whole subwoofer; so I took the gamble. The old subwoofer used to cut out at high volumes due to heat and no heat sink on the back of it. When you’re at the pool and really cranking the tunes at high-volume you really want that bass response to stay on target....when it drops out it ruins the whole song. Installation of the new amp involved making a hole in the back of the original cabinet a little larger. A little minor surgery with a jigsaw and a fine tooth blade was all it took To make the new amp fit snugly. The new amplifier drives the 12 inch driver just fine with a lot more power And response. As suspected, the original BIC plate amp was weak, muddy in response and essentially shite. Frankly, I think it was insulting my music . I’ll keep abusing this subwoofer at high volumes for a few months and report back. If this sub woofer does not drop out after prolonged high-volume usage over the next few months, then I’ll assume the five stars I gave it from the offing are warranted.
