Not so sure.

This amp seems to be well made, but it lacks power to drive more complex systems. If you have a small car and are using some fairly cheap coaxial speakers and an 8" to 10" sub, it may suffice. For me, it just didn't do it. The sub channel was a bit weak.

Pros: Compact Size Ease of Installation Easy to set gains and filters

Cons: Weak subwoofer channel

Great power and quality with solid adjustability

I installed this in my '24 Jetta with a full Polk component set, AC LGD-20's and a JL Audio 12in sub. The amp has more than enough power for a setup like this and the level of adjustment the ACX offers let me correct the sound how I needed it for the design of this smaller car. It's extremely well made and has performed how I'd expect for the price. The Accubass setting is fantastic for anyone with a factory head unit who doesn't want to run a LOC or DSP and needs bass correction. I'd highly recommend this amp - only note is that when using high level inputs you have to cut off the supplied RCA inputs and splice the amp's harness rather than hooking up normal connections.

Great amp so far!

Jeffrey from Bend, OR on 3/8/2024

Awesome amp so far (only had it installed for a few days), but sound and power are great! I'm uisng it to replace my super high end ADS (Analog Digital Systems) amp that gave me 25 years of service in 4 difference vehicles with hard use! I don't think any of the modern amps sold nowadays could ever compete with that, but time will tell! (If I live long enough! :-) Also love the wiring harnesses that came preinstalled due to this being a Marine amplifier (note, I'm using it in a standard,dry-land vehicle). Makes connections easy. Great value for the price too!

Pros: Quality, great sound, awesome power, easy install

Cons: no built in tv or grill

Fits under the passenger seat of 2014 EXL Navi V6 Accord coupe with all AC speakers. Sounds amazing.

Pros: Fits under the seat Sounds amazing with AC speakers

Cons: Took the shop a while to sort the inputs. Maybe a Honda thing.

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
