- Reviewed in Canada on July 16, 2024Verified PurchaseReplaced two old amps with this one amp.
Power to the front speakers went from 60 watts each to 125watts each (4ohm load), and power to the subwoofer went from 250watts to 350watts (4ohm load), stuff's louder is what I'm trying to say, all while having good sound quality, the price is great too.
One thing to note though, this amp does not have a remote sub controller, you can use an rca level controller on the sub channel input though, there're cheap and 鶹 has a bunch of them for sale.

- Reviewed in Canada on June 5, 2024Verified PurchaseSmall footprint in D-class amp. Used on 6-1/2 2 way and 2 set of tweeter. Sound good but goes into protect mode, cut in and out after a min or two of playing.
- Reviewed in Canada on May 5, 2025Verified PurchaseIm not an audio expert but it seems this amp is a 4 channel ONLY. There's no 2-4 channel mode switch. So, if your head unit in your car only has 2 rca port (left/right or front/back) you'll have to purchase 2 Y splitters to get sound to all 4 speakers. The tradeoff is that you can no longer adjust balance with left/right because the Y splitter duplicates the signal from each rca cable. Personally, I don't really care. I bought it because it was cheap.
It's safe to say this probably isn't 1500W (usually requires 2 batteries or an upgraded alternator to utilize all 1500W for an extended period of time). Even if it's 500W, that's more than enough to drive 4 speakers in my opinion.
- Reviewed in Canada on April 10, 2025Bought this to replace old JL audio amp with a lot less power then this one I was not impressed at all amp over heats quickly and did not sound good at all my old JL amp rated at 680w sounds much better and hits so much harder and it 20 years old. Don’t waste your time go and find an older Fosgate or JL you will be much happier.
My JL has never overheated and shut down but this one after about 20 minutes cut in and out. I have been installing car audio since the 90s and I would never buy these again

5.0 out of 5 stars Great little amp for the price
Verified PurchaseI own a lot of vehicles and I gotta have a lil bump in each one. Owning 7 different car audio systems can get pricey so the work truck ended up with the leftovers from storage. This lil amp is running 4 coaxial speakers at 2ohm stereo off the front channels and a pair of Memphis 10s bridged at 2 ohm mono off the back channels. It is more than enough for my lil single cab pickup. I have had no issues with overheating and the compact size is just perfect as it can be put just about anywhere. Previously trying a small Taramps 4 channel there was a ton of noise and fuzz, this amp has none of that and sounds great.

5.0 out of 5 stars Power and clean , wish it has Allen connections
Verified PurchaseVery amp puts a lot of power small footprint makes it easy to melt I do wish it used the barrel style Allen connections instead of the spades as I feel that that's kind of a weak link and makes the connections longer than they need to be sticking off the app little bit less clean if they could update that this thing were definitely be more than a five-star.
