Buggy software and zero support from Alpine

Tim from COOPERSTOWN, ND on 8/9/2023

Verified customer

I spent a large amount of money on this thing, because I wanted all those channels of DSP. The software is easy to understand, but the problem is that the settings don't stick. I managed to finally get all crossovers set after 3 sessions, but haven't managed to to get the equalizer to do anything noticeable. I've sent 2 emails to support about it, but I haven't had a response. (Yes, I check the junk folder) They did however immediately sign me up for marketing emails after sending in the support request. Could be an absolute winner of a product, if the software wasn't so bad... Unfortunately, I'm going to just have to break down and PAY an Alpine dealer to set the DSP up, and I suspect I'll get charged plenty of hours, since the software is so bad.

Very clear, rich sound, full of features - I am wow'd

I applied this amplifier to a 4-speaker + sub speaker setup in a '97 Corolla.. The outcome was overwhelmingly great; way more than I expected. My speakers are rated at 100w RMS, take quite a bit of power to push effectively, but even at 50w per channel it is outperforming my older 90w/ch amplifier. The power/quality this amp produces is incredible, especially when playing 192kHz/24-bit music. Even when playing Pandora or other internet radio stations over the amp's bluetooth, not using hi-res, this amp is unmatched compared to any previous amplifier I have heard/owned. 10/10 would recommend!

Pros: Crystal clear, rich sound quality at low or high volumes. Hi-Res playback. Ability to use amp as a preamp or chain a second amp to ch 13/14 while using main 12 channels. Ability to use amp's bluetooth input to bypass head unit as a source. Features galore.

Cons: Slight learning curve if not used to application-based DSP amplifiers. Once you get the hang of it, it's not bad!

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.
