Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier

A great amp to replace the blown amp in my powered Paradigm subwoofer. I initially rescued the subwoofer from the recycle center in town. Get it home, plug it in, connect to my system, nothing. The amp that was part of the subwoofer was unresponsive. My brother repairs electronics, sent it to him (the amp only), he couldn't get parts that were compatible, it got tossed. After a lot of research, I decided on the Dayton Audio, since it would give around 500 watts at 8 ohms. I had to modify the subwoofer enclosure to fit the amp. on the first system I hooked up, a pair of powered PSB powered speakers that had a subwoofer output, I did have some hum, but it did work good. I had an issue with my main system, speaker wire had to be repaired, definitely not average, run of the mill. It is Audio Envy SP13, and also new to the system is the SP14. I have bi wired my speakers for nearly 30 years. Both runs of the AE speaker wires I would put up against any Kimber, Audioquest, Cardas, you name it, for the money, the performance is OFF THE CHART.The amp running off of the dedicated subwoofer output signal from my NAD 165BEE pre-amp, and the subwoofer relocated to a different spot, I get ZERO hum. I don't have the volume maxed, and the subwoofer is only adding the lower bass, augmenting the 20-45 hz range. Well worth the money I had to spend, since I only had replace the amp, I ended up with a $1350 subwoofer for only $550, plus the mandatory tax. Great power, didn't take up a lot of room.

Hasta el momento tiene buen rendimiento con un par de 12', las mueve casi a reventar, me llama la tencion que hace un "pop" al encender y cuando esta a niveles altos se calienta espero sea normal... lo compre en oferta 7500 creo que fue un excelente precio. Lamentablemente hoy 14 de septiembre comenzó a meter ruido y tengo que llevarlo a reparar.

As long as you hook it up correctly this amp will make a set of 15 inch kickers slap. I love it so far. Going on a year of heavy use.

Spent a lot of money on this amp, now have an expensive paperweight. As others mentioned, this amp suffers from horrible 60hz hum that cannot be resolved. I spent too long trying to remedy the issue on my end and now can’t return it. Now I have to pay to ship it in to get “investigated”. All other amps I’ve used besides Dayton work perfectly with minimal noise. If the hum wasn’t bad enough, it also pops loudly when turning on/off, which happens frequently due to poor input detection. Cannot recommend this amp at all, especially considering the significant cost.

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!
