Alpine S2-A55V

Great amp for the price! Lots of adjustments to dial it in perfectly and plenty of clean, clear power. Installed in my 91 regular cab s10 with Infiniti 4x6 References in dash, Kicker 4x10s in B pillar, and 2 Kicker 10s behind the seat. Lots of juice to get the 10s pumping. Very satisfied! Would've given it 5 stars if remote bass knob was included.

Cons: Remote bass knob not included

Small enough to mount a lot of places. Powerful enough to run a good system

I am powering a set of Audio Control 6x9 components and a JL Stealth Box with a 10" woofer with this amp. No problem after a 5 hour drive.amp ran cool and provided great bass. I got this because I could fit it under the seats of a Toyota Tacoma. Alpine has a solid reputation for their Amps and this one did not disappoint. I made a few mistakes while setting gain with a distortion detector and the amp protected itself. Excellent sound quality. I mostly listen to large .wav files from my USB sticks and am happy with the detail and smoothness of this amp.

Pros: Compact, runs cool and stable into lower ohms

Cons: Wish I could completely bypass the crossovers

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.
