Dayton Audio SA100 100W Subwoofer Plate Amplifier

This amp plate is worth every dollar. I replaced a blown amp plate in a Infinity HTS20 system and this plate I think is WAY better then what was in it. It required opening the hole a little. The plate is very well built. It is made with a nice heat sink on the back. The Infinity amp plate did not have have any at all. It also has nice banana jacks which the Infinity had those cheap spring one. Even Has auto shut when not in use. Amp is totally enclosed as well. Very Very impressive . I was going to try to have my old plate serviced but the pc board was total coated with some type of epoxy on it. Then I read the module usually blows because of electrolytic capacitors going bad. And I thought Harmon/Kardon Built Quality products . Everyone needs to rethink that one. So glad I consider this plate. The unit sounds even better then before.

I've been using it in my old Denon A32 sub-woofer and it works as good as new. Still have my 1998 Denon receiver, subwoofer and CD carousal. Love the classics.

I purchased this to breathe life into a BIC F-12 subwoofer who’s plate amp had failedThe 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.

Good output no distortion at proper settings overall nice for the money

Fit my Polk Audio 10. Sounds great. But is only good for moderate use for a few years. You get what you pay for. Original PA amp lasted me 12… this only 2

I dont usually write reviews, but I figured I would do so for these products because theyre a specialty product and I read some reviews that seemed like maybe people didnt understand what they were purchasing.First of all, the only negative thing I have to say about my whole experience, is that I was disappointed none of my purchases through Parts Express were covered under my 2-day Amazon Prime shipping. HOWEVER, I did not feel cheated because I had to pay for shipping since my purchases actually arrived sooner than items I ordered through Amazon. Yeah, I had to pay extra, but the shipping gets an A+ from me. Also, everything was always packed tight, lots of cushion, and box within a box. I work for a large brown shipping company and believe me I see poor packaging allllllll the time. These people are on top of their game.I mounted 2 Bass shakers with a steel plate to the steel frame of my couch. I wired them at 8 ohms to a Dayton Audio SA100 amp, and switched out the stock feet to my couch with the Buttkicker brand isolators. WOW! These things work magnificent! If youre on the fence about purchasing these things just do it already! You wont regret it! Im a bass junkie, I have 5 subs hooked up to my system, but with these hooked up I havent even turned on 2 of them since my install. I mainly watch movies but it seems these will work great for music as well.If you plan on using this for transducers, this is all youll need to power 2 of them. I have it set at about 85 hz and the level is at about half. I only wish there were boxes available for these without the speaker hole already cut out but Im sure it wont be hard to make one.

I use it for an under desk music bass fill. Plenty of power for that. Lower distortion than most. It might even be big enough for a small room music sub. Not HT or special effects. It lacks variable phase that may be an issue for sum. If so, the BASH plate would be my next choice. I have two of them.

I used this to replace the powered subwoofer in a Polk audio subwoofer which went through 2 amps in about 5 years. I had hoped for better longevity with this one when purchased in Dec 2022. This is a nice product , fit well, and sounded great. Now in Dec of 2024, it is dead. A very muffled, low power bass comes out, the lights are on, but it no longer works. I wish I could find one of these that lasted more than a couple of years before joining the e-waste heap. Sigh.
