  • Great value, get em while gettings good!
Size: R2 - 1000 watts max, 2Ω
The media could not be loaded. I needed a budget amp for my truck and I had seen Big D's amp dyno video on the MR2 amp and met and exceeded it's ratings and it is tinsey the footprint isn't much bigger than a cell phone, but it was out of stock but the R2 was the same price and same wattage but at 2 ohms and it's a A/B class. So I rolled the dice and ordered it and I can say I'm quite pleased it feels nice and solid well made and it seems to make the advertised power and sounds good. The whole A/B class sound quality being superior isn't relative these days class D is so refined nowadays you are not going to hear a difference on a subwoofer if there's even any difference nowadays. It has a clipping light that's nice and unheard of on a budget amp, it also has dual output terminals vs the MR2's undesirable super small gauge wire going through a molex connector. Down sides are that class A/B amps are not as efficient and consume more power than class D and they run fairly warm at all times, is it a problem prob not if its not smothered in a tight spot could be an issue under heavy use, another it has plastic mounting feet molded into the end caps they didn't break but there not as strong as metal ones, it has spade type screw terminals not lugs..boooo. Also it's only 2 ohm stable but on the up side it still makes 500+/-wrms at only 2 ohm not down at 1 ohm and 1 ohm stresses an amp more and is typically less efficient. It's alot larger than the class D MR2, that's not an issue for me I have plenty of room plus the larger size looks more impressive than the tiny tiny MR2. Overall it's a great value it actually makes me consider there 4K that's $399 for my caravan to replace my 1200+wrms Pioneer GM9701 but by time I ready to upgrade the price will have gone up. I imagine all Toro Tech amps will go up in price before long unfortunately. ... show more

  • Well worth every penny... super good deal for the money
Size: MR2 - 1000 watts max, 1Ω
Awesome little amp... I bought this 500RMS amp after watching BigDWiz on YouTube dyno this amp and I've been hooked on Toro ever since... this little tiny amp person is amazing... I hooked it up to a 10in Rockford fosgate p2 and it bumps really well and sounds awesome... I highly recommend the whole Toro line of products... ... show more

  • For the Money
Size: MR2 - 1000 watts max, 1Ω
For the money and size, you will NOT do better. I am pleasantly surprised with the clarity and power these little things provide. Needed a small footprint for the Jeep, and these fit the bill. I usually don't write reviews, but had to come here and share my experience. Running the Mr2 @ 1ohm to a Alpine Type R 2 Ohm DVC in a truck "Q bomb" box in the back of a jeep wrangler and it sounds amazing. I also have the Mrx2 running 4 Polk Dbs at 2 ohm per channel and the clarity and power is also shocking to me for the size. Also...neither are remotely hot running for 10 mins at almost full volume. Great job Toro! I'm a fan. ... show more

  • Could be a good budget amp
Size: R4 - 2500 watts max, 1Ω
I ordered this to go with a single C.A.B ultra 12 I received as a surprise me package and use them as a back up to my Zv5 12 thats coming in tomorrow and Pure Audio 3000.1 which in being replaced by a wolfram O series 5000.1 when it comes out in August. I came across a ad on FB for this company and checked them out. The 2 big things that helped persuad me was first the price ... i was a little skeptical at first because it was low low and second was the honesty on the RMS of the amp. Most companies over size and push the peak power with huge numbers and if they even do post rms its not close to true . Toro puts wattage at each ohm and i believe it could be true. I have not hooked it up yet or the sub. But I do like how the amp looks, how it was packaged. I will do a update after i hook it up and play it for couple days. ... show more

  • Zero complaints
Size: MR2 - 1000 watts max, 1Ω
I was skeptical about this thing, but the overwhelmingly positive reviews here and an amp dyno video on YouTube convinced me to pull the trigger on it. So far, I'm pretty impressed. I've previously used one of the Rockford PBR series amps in a different car, but this thing is even smaller and puts out about the same power. At a much cheaper price point. Edit: 2.5 years later and it's still going strong! ... show more

  • Well made!
Size: MR2 - 1000 watts max, 1Ω
I have not installed yet, so I’ll update after I do. Appears to be incredibly well built and of higher quality than its price point. I can’t wait to install and hear it. UPDATE: I’ve had this mini monster installed on a single Audio Legion 12” 2 ohm DVC sub, bridged to 1 ohm mono for over a year now. Trust me when I say this thing is impressive for its size. I’m not “nice” to it by any means, and this thing takes it like a champ. I’m an ex “Pro-class” IASCA competitor and have had amps from all the old school giants that cost 5 times what this little guy does that didn’t hold up this well for this long. I honestly think I’ve found my new favorite budget friendly audio brand. ... show more

  • Only worked for a couple weeks
Size: MR2 - 1000 watts max, 1Ω
It is very compact and does rated power, but mine didn't last long. I set the gain using an oscilloscope and tuned it conservatively because I had subs that couldn't handle the full 500 watts, and the amp still only lasted a couple weeks.

  • Big big amp in a little tiny body!
Size: MR2 - 1000 watts max, 1Ω
I had to have a small sized amp because I was replacing a factory amp and wanted to put it in the same spot in the car. This amp can put out some major bass and is easy to install. I love listening to music in my car now, thanks to adding this amp and a sub!
