XS Power 3/8" Stud Adapters

Does not fit optima battery or xs power side post.

Cons: Does not fit xs power battery terminal adapter for side post. Feels like it's cross threading while trying to install

Thank you Crutchfield. These are exactly what I needed. I was concerned that the M6 stud was too long (as per the photo). My battery terminals are not that deep. I went ahead and ordered confident that I could simply cut them down to size. No need! They arrived (the next day!!) and the M6 stud length is half what is shown in the picture: which is a perfect fit for my application.

Pros: Solid brass. Perfect fit.

Cons: Not a con but I would rather they came with brass wing nuts and washers.

Used on a Braille battery to give me a stud to slide my stock GM side post terminals on (once I removed the stock bolts). Works great.

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.
