5 stars for both harnesses, two and a half stars for the one I used.

My biggest complaint is that this harness is so expensive, even when bundled with a head unit and other things. I found out why it is so expensive though: The kit is actually TWO harnesses. You use one or the other, then throw the other one away. It's quite wasteful. All they would have to do to fix this is give each harness it's own part number, and let me choose which one I need. It's not a mystery.. Oh wait, they DO have their own part numbers: LD-AX-XSVISP1 and LD-AX-XSVISP2. This is just laziness from the manufacturer, and appears to be a plan to sell more harnesses. It took me a week to talk myself into buying this due to the cost. The radio I used was $80, the harness kit was $87. There's no reason the harness should cost more than the radio, should have been $40-50 at most. It's all made in China. If I had more time I would have shopped around for another option, or repurpose the harness that came with the previous radio I was replacing, which is an all-in-one so you can use either/or and be done with it.

Pros: Works as expected.

Cons: Relatively expensive.

Worth the price

Purchased the Axxess harness to solve a problem I was having with radio install in my 2012 Sprinter van. Having done his type of thing in many of my previous cars and trucks, I felt more than capable of wiring a replacement radio. The tech reps from both Kenwood and Crutchfield recommended the harness as the solution, I thought it kind of pricey, but bit the bullet. When that didn't solve the problem, I messaged the Tech guys at Axxess and they were able to point me to the problem, it was an issue created by the wiring of the new front speakers with separate tweeters, although I followed one of two wiring directions in the instructions, it was displaying a error wiring message. problem solved, great product, great tech help.

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.
