Set up a free consult with our A/V design team to get started

Coastal Source is known for their high-performance, all-but-indestructible outdoor audio systems. The CRS4K amplifier requires manufacturer configuration to match the speakers and subwoofers you'll be driving with it, and Crutchfield will guide you through that process. To get started building your dream outdoor system today, you'll need to contact an A/V system designer to set up a free consult.

A powerful, customizable amplifier

This powerful and highly customizable CRS4K amplifier isn't weatherproof — you'll need to install it indoors — but there are plenty of ways you can use it to power an indoor or outdoor sound system. The CRS4K delivers four channels of clean power rated at 1,000 watts each. It's 2-ohm stable and capable of driving a wide range of speakers. And it's designed to fit into a 1U rack space.

Flexible operation and connections

This amp uses Phoenix-style line-level input and speaker output connections. That allows you to use traditional wiring to power four speakers in one or two zones, or bi-amp a pair of compatible speakers — like the Razor RZ310. It can also be configured for 70V operation in a commercial sound system.

Two included pairs of CRS RCA Input Cable Adapters let you install analog audio sources with RCA connections. You can also get adapters for balanced XLR input and Coastal Connector speaker output (both sold separately).

4,000 watts total (1,000 watts x 4)

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.
