Best Car Amplifiers of 2025

"I needed to replace an old amp. This one isn't as loud, but it sounds clean, and the price was right. I'd buy it again."

"I've had other brands, but this little amp makes my car speakers scream. For its size, it's very powerful, and the value is perfect."

"I was impressed with the zero distortion at max volume. This amp truly delivers loud, clean, crisp sound and thundering bass. I'm glad I opted for better equipment."

"I bought this amplifier for my son's first car, and I have to say, it really pushes his 10-inch Kicker sub in a ported box quite well. The bass is deep and loud; at times, we even had to turn down the amp because it was a bit too much. We adjusted the gain while keeping the remote at max to find that perfect balance."

"After installing it in my 2005 Ford Focus, I was pleasantly surprised by how hard it hits with a ported 10-inch sub. So far, it hasn't overheated, which is a plus."

"This amplifier is a great bang for the buck. My son needed an amp for his small subwoofer, and this one does an excellent job pushing his 10-inch speaker."

"I installed this amp to power my two Kicker CompR 10-inch woofers in a sealed box at 2 Ohms. I listen to a lot of R&B and deep bass music in my 2017 Mazda 3. Initially, I thought this would be a temporary beginner amp, but two years later, it’s still performing well! It definitely delivers more bass than I expected."

"I recently connected this amp to a Jensen J12W 12-inch subwoofer, and I'm impressed with how well it drives it. Even with the crossover set low, it still manages to bring some vocals through, but overall, it's a fantastic amplifier. I've had it since September 2023, and it seems built to last."

"This amp has been a great addition to my sound system. It provides more than enough power for my two 12-inch subs. The installation was straightforward, and it even came with all necessary mounting hardware. I highly recommend it for anyone looking for an easy setup and solid performance."

"I was blown away by the performance of this amplifier! With 1500 watts of power, it delivers crystal-clear sound and deep bass that really enhances my audio experience. The installation was straightforward, and the build quality feels solid. I love the versatility of this 4-channel amp, making it easy to power multiple speakers. If you want an amplifier that combines power, clarity, and affordability, the GP-2000.4 is an excellent choice!"

"When I first hooked it up, I thought the amp was broken since all the levels were turned down. After adjusting the gain, it totally exceeded my expectations! This amp is awesome, especially with the red lights on top. It works great with class A and B speakers, and really pounds on the class D subs. Just remember, if it's brand new and seems not to work, turn up the gain level!"

"I have to say, this amp has some serious sound quality. I have 4 8x7 Pioneer speakers in my truck, and while it struggles at higher volumes, the sound is very clear. However, it does get freakishly hot and goes into protection mode even at low gains. But for moderate listening, I'm satisfied with it, although I probably wouldn't purchase this model again."

"I've been using this amp for over 8 months without any major issues. It did overheat a bit during the Texas summer, but that's to be expected."

"I wanted to separate my front tweeters from the door components, and this amp has plenty of power. While I'm a bit less impressed with the sound quality compared to my Class AB amp, it still performs well overall."

"I was skeptical about this tiny amp, thinking it couldn't deliver, but I was blown away! It produces clean power, and for its size, it's just incredible!"

"I purchased this amp to replace a failing DD 5ch amp, and it fit perfectly. It delivers more than enough power for my 12" sub and 6x9s in the back, along with 6.5s in the front. The hookup was straightforward, and I’m thrilled with the sound!"

"I decided to try this amp for my FJ Cruiser budget stereo build. Despite its low price, the quality is impressive! It really packs a punch and meets all my expectations."

"I’m using this amp to power my mid highs and a small sub, and it works extremely well. The sound quality is very clean and the power is adequate. I’m definitely impressed and feel it was worth the investment."

"I purchased the 3700 Boss 5 channel amp aiming for a balanced sound for various music genres. I not only achieved that, but it’s louder than I expected. My setup includes two 6.5" 3-way speakers up front and a Pioneer Comp Sub in the back, and it sounds fantastic. I ran into some engine noise initially, but I learned that running the RCA cables away from the power wires resolved it completely. I believe many negative reviews stem from improper installation. After tuning my setup, it has performed like a champ, staying cool even at high levels!"

"This amp seems to have been designed with all installation scenarios in mind, including a 5th channel for a subwoofer. It’s powering my speakers and sub with great clarity even at highway speeds. I really appreciate the solid build of the unit. My only complaint is with the wiring kit, which I wouldn’t buy again, as I prefer real copper wire for better performance."

"At first, I had a scare when it didn’t work for all channels. It turned out to be a loose RCA jack, and once I fixed that, everything worked perfectly. I adjusted the gains to find the right sound level, and now I’m only using about 25% volume and get a clean, crisp audio experience. I did notice some hiss in surround sound mode, but it’s not a big deal since I rarely use that feature. Overall, I’m loving this amp!"

"I added this amp to my factory system in my Jeep Patriot. After replacing the stock 6x9's with Kenwood 3-way speakers, the sound is impressive. Each speaker runs on its own channel, though I feel like the speakers struggle with the power. I'm planning to upgrade to Rockford speakers soon to see if they perform better. Overall, I'm quite satisfied with the amp so far, and it's a great, affordable upgrade to my factory setup."

"I installed this amp in my 99 Jeep Cherokee. It works just as intended and the adjustments are user-friendly. It was easy to install, and I'm pleased with how it performs."

"When I first hooked up this amp, I followed the same process I've used with thousands of others, but it burned out before I could tune it. It wouldn't power on anymore and produced no sound at all."

"Before I get into how impressive this amp is, I must mention how difficult it was to find the RMS ratings. Initially, I was skeptical because of the low price and thought my 3500 watt version (which is actually 170 watts RMS x 4) would sound distorted. After replacing my Pioneer 125 watt RMS x 4, the sound difference was remarkable. My music now sounds crisper and more alive. This class A/B amp is so loud that I can’t turn it all the way up, as it makes my speakers pop from too much power and bass. I highly recommend this brand and this amp. Good car audio doesn’t have to be expensive! Just ensure your wiring is clean since it lacks circuitry to clean the input, but a RCA filter should solve that issue."

"I've been really pleased with this amp so far! I'm running it with two kicker 12's at 2 ohms, and I've encountered zero issues. However, I must say that the bass knob is pretty much useless; it either works at full blast or not at all, with no noticeable difference in sound between those settings. Other than that, this amp has been absolutely fantastic!"

"Honestly, I was really disappointed with this amp. I had it professionally installed, and compared to my 300 watt Fosgate, this one was a letdown. Even my factory amp with a 6” sub outperformed it. By the time I could get it installed, it was too late to return it. I think Orion should be ashamed to put their name on this."

"I replaced my old JVC amp with the Blaupunkt to drive my Infinity Kappas. I should have done this sooner! The sound quality is impeccable with insane lows and crystal clear highs. It's compact, making it easy to fit in my car."

"I give this 4 stars for the value alone. It doesn't quite deliver the watts it claims, but if you set the gain and bass boost wisely, you get a decent amplifier for the price."

"I was impressed with the packaging and build quality of this amp. The sound is crisp and clean, with no hiss, unlike my old amp. It's perfect for my JL tower speakers!"
