Product Details

Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier

The Dayton Audio SPA1000 is one of the most technologically advanced subwoofer amplifiers on the market today! The Dayton Audio SPA1000 subwoofer amplifier is based on a state-of-the-art Class-G circuit topology that combines the proven high power, high fidelity characteristics of a Class-AB amplifier with a patented tracking down converter power supply to achieve an operating efficiency up to 86%. You get the efficiency of a Class-D amplifier without compromising audio quality and reliability. The Class-AB output stage provides the clean and low-distortion sound that audiophiles demand, without any of the instability problems that plague other high-efficiency amplifier designs.

This American-designed and engineered amplifier uses patented circuitry that continuously tracks the input signal to modulate or control the voltage available to the output stage. This "tracking" capability delivers the exact amount of power based on demand instead of constantly keeping it in reserve, so the output stage only draws the amount of power that is required at any given time. Less energy is wasted as heat, and more power is available for the subwoofer driver. With its enhanced thermal management, the SPA1000 is an upgrade over previous models—making it a nearly bulletproof amplifier choice for today's demanding HT audio and music playback applications.

Specifications: • Rated power output: 497 watts into 8 ohms, 950 watts into 4 ohms with 0.92% THD (based on one-third power duty cycle) • S/N ratio: 98 dB (A-weighted) • Low-pass crossover: 30 - 200 Hz, 24 dB/octave • Parametric EQ: Frequency: 18 - 80 Hz; Bandwidth: 0.1 - 1 Q; Level: -14.5 dB to +6 dB • Phase Adjustment: 0° (NOR) or 180° (REV) • Input impedance: 12K ohms • Input voltage: User switchable 115V/230V (Euro cord available) • Stand-by power rating: 115V 24W; 230V 18.4W • Efficiency: 86% • Net weight: 17 lbs. • Dimensions: 11-15/16" W x 11-15/16" H x 5-1/4" D; Cutout dimensions: 10" W x 10" H.

Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier
Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier is rated 4.5882 out of 5 by 17.
Rated 4 out of 5 by from Fantastic Performer!I purchased this amp to install in my new sub kit from PE. The plate amp fit nicely in the back of my PE 18" Ultimax sub kit. The adjustability is adequate and easy to use. The amp is driving the 18" UM driver without a hint of an issue. To be fair I haven't cranked up the sub yet as it's new still. I fear what this amp can do.My only complaint, and why it got a 4 is the short leads. At ~20" in length they were barley able to reach the connections on the DVC driver. It would be nice to have a little longer leads, especially since this amp is promoted specifically for use with the 18" UM kit from PE. I know I can add wire easily but still.......Overall I'm very pleased with this amp and would highly recommend this to anyone looking for lots of power.

Rated 5 out of 5 by from Bass complexAfter my Yung plate amp died while not being used (powered up, and off, on its own) , days after the warrantee expired,I found out PE will fix their house brands even past their warrantee.Tried out this one, for a pro audio 18", 1200 watt driver in a sloped H frame, previously Yung powered.The SPA 1000 is superior in every way.No strain, effortless, pitch perfect bass lines.The variable parametric eq is far superior to a fixed 6 db boost, and the gain control has far better low level adjustability than the previous amp.This isn't a thumper, unless that's what's called for. This amp plays music.

Rated 4 out of 5 by from A lot of powerIt has a lot of power, but there are two things that really bugging me, when I turned it on, it sent a surge of power to the driver, making that thumping noise, that very bad for the driver, and the standby mode led glowing green, I thought the amp was on all the time, when it turned on led glowing yellow, should it be the other way around ?

Rated 5 out of 5 by from Powerful sub amp!Sounds great. Easy to setup in my cabinet. Really drives low end.

Rated 3 out of 5 by from Has some powerHad a 500 watt subwoofer from an Iowa manufacturer that no longer exists fail. The speaker was capable of handling more that 500 watts so I got the SPA1000. I had to cut the cabinet to make it fit but I was expecting that. After spending some time getting the amp to fit I was very disappointed. The amp rattled horribly. I ended up having to remove the amp and pull the cove to find that pretty much every screw on it was loose. After tightening them all up and putting it back together it works great. More than enough power for movie watching.

Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier

Need a 4m  power cable to reach my power conditioner.   Any issue with this length with this amp?

Asked by: kerryd
As long as the cord is at least 18 awg but preferably 16 gauge or larger you will be ok. This amp can draw up to 8 amps and an 18 gauge power cord is rated at 10 amps max.

Have this hooked up to dayton 12" 2 ohm dvc in series.  Using stereo pre-outs from integrated amp.  Integrated is on power conditioner.  Plate amp is not.  Am getting some ground hum.  Thoughts on how to resolve?

Asked by: kerryd
Tech Help:Remove the input signal first, If hum goes away then its coming from your pre-amp. If not, then try making the grounds common ( same outlet or strip) or try a ground lift on either component.

I have two DVC subwoofers with each voice coil of 4 ohms. In order to generate a load of 4ohms, I an either wire speaker coils in parallel(2ohms each) and both the speakers in series(4ohms) or vice versa. Which way is better ?

Asked by: Bhuwan
It makes no difference, the end result will be exactly the same either way.

Is this amp 2 ohm stable? I would like to drive two titanic 12" subs that are 4 ohms each. I would be driving them in parallel which would make it a 2 ohm load. This is the reason I would need a amp that is capable of a 2 ohm load safely. Thanks, Max

Asked by: Madmax48
The SPA1000 is stable down to 4 ohms.

What size drill bit should I use to drill the holes and what size screw should I use? Do you have a set of screws that you sell for this particular amp?

Asked by: Chris Branstrom
This amplifier includes mounting screws. Generally you will want to use a drill bit that is about the diameter of the shaft of the screw, minus threads. This will probably end up being something close to 1/16" or 3/32", but you can verify by comparing the screw to the bit used.

Assuming an enclosure made of 1" thick MDF, how far into the enclosure will the amp protrude?  The specs say that it is 5" deep.  Mounted on the outside of the enclosure, will it actually stick into the enclosure a full 5"?

Asked by: dleitner
Yes, the actual mounting depth for this amplifier is 5", but you will want to allow about 1/2" for the wire lead as well. If the amplifier is surface mounted, I would recommend a total depth of 5-1/2" measured from the mounting surface to the back of the amplifier enclosure.
