Dayton AudioSPA1000 1000W Subwoofer Plate Amplifier

Used one of these 1000w amps with two 12" Polk Dxi subwoofers for a dyi home theater subwoofer.Pros : I really like the subwoofer controls and eq although I ended up using the LFE input which bypasses all controls except the gain. Very well built with a beefy transformer. Auto power on sensing seems to work well so far.Cons : Nasty "thump" when powering on(not when auto sensing though). Would be better if a 12v trigger option was offered.

Unit came damaged but I hooked it up anyway.Only to find it did not work.It would suck the speaker inward whan switched on, then come back out when switched off. Did nothing when signal was applied.Total junk. Returning as I type.

I bought this to replace/upgrade a failed SPA500 that was ~10 years old in a direct to consumer integrated subwoofer. It was a drop in replacement, took me about 10 minutes and most of that was because I chose to use a hand screw driver rather than a drill for half of it. So far it works great, I don't know if I "needed" the upgrade who can say no when it was far cheaper than any new sub alternative.I could possibly fault Dayton for the fact that I have 2 SPA500 that failed, but maybe 10 years is all I can expect from a sub amp? Perhaps they are working too hard due to the wiring arrangement of my subs. They are powering 2 15" dual voice coil drivers in a sealed enclosure. It is hard to say, but I have two of the SPA500 had a failure that resulted in them just humming non-stop (and no, it wasn't due to ground loop) which isn't unheard of...but then what competitor exists remotely close to this price point?Hopefully the SPA1000 last longer than the 500 did, but it was still far cheaper than buying new subwoofers. I am sure the bass will be more intense with 2000W total driving my 4 15" subs when I install the 2nd amp in a week.

Driving 2 earthquake sounds 15 inch speakers, I can literally shake the house. Probably all the power you could ever need.

So I purchased this to replace my Klispch 115 SWR amplifier after it died. The difference is night and day as far as features, build quality, and power goes. I doubt the Klispch stuff makes more than 250w with lightening as a power supply. This SPA 1000 is definately worth the price at about .50 per watt. Not too mention the clipping protection, great EQ, and AB class with a massive Xformer.I actually threw the Klipsch woofers in the trash where they belong and installed Sundown subs. The house is now powered with 3 of these amps on Sundowns in Klipsch enclosures. What a difference!

Very clean sound, with no clipping or distortion. The on-board equalizer eliminated my 15" Cerwin-Vega subwoofer enclosure's reverberation excellently. It cut only a very narrow frequency band to cancel out the excessive cabinet vibration.I thought a 1,000 Watt peak amp would be louder, but this amplifier & subwoofer combo still significantly outperform both of my 15" 3-way C-V floor-standing speakers, so I guess I should be content. The three-some sound fabulous together. Definately a strong 4 stars for this Dayton plate amp.

Product looks legit but it has serious ground humming and it cannot handle 1000 watt speaker at 4 ohms like it say. It cannot handle gain at half way without shutting off. I constantly have to turn it off and back on again for subwoofer to work. Also the automatic trigger turn on sometimes work sometimes doesn't. I tried everything from buying new rca shielded wires to plugging everything into same power conditioner outlet to using isolators. Nothing works.. I tried contacting them but no reply. I explained my problem not wanting to return it but to help me fix the problem and no answer. Just put out a little bit more money and get a Monolith 12 with none of these problems.

I bought this amp to build a home subwoofer. It was the largest rated amp I could find to drive 2 12s. From a workmanship perspective I don't have any issues with it. When I hooked it up to my multimeter in order to try and set the gain, there is NO WAY this thing puts out 1000 Watts RMS. Its more like 600ish. That being said, after tuning the subwoofer level with my SPL meter, I found I didn't need quite all of it. End result is a home theater with wife approved bass. Personally, I like it when the house shakes as things explode on screen. Next time (and there will be a next time) I think I'll use a Behringer EPX instead of looking for a plate amp.
