FOR CAR AUDIO, HOME THEATER, FLAT SCREEN TV, HDTV and alarm systems, Phase 4 Stereo and Electronics in Idaho Falls has been the most trusted name for years. Located in Ammon, has low prices to beat Best Buy or any of the chain stores and unparalleled service.

Here are what some of our customers say:

Bought my first mid-range speakers from these guys. Gentleman sold me on an alternative that Best Buy was selling (both were klipsch), beat their price, and explained the subtle differences between the two.

The Subwoofer I purchased was on par (just slightly more expensive) for pricing with what I was seeing online, which is rare for brick and mortar.

The Speakers I bought were actually MUCH cheaper than I was finding online (On sale). In fact I was able to go with speakers a bit better than the ones I intended on purchasing because of the pricing.

"I wanted to buy a new TV for my husband, but had no idea where to start. I shopped around and the only place I felt like they knew what they were talking about was Phase 4. I also appreciated that they weren't just trying to get me to buy something and get out the door. They really talked to me and helped me decide what was best for us. I would recommend them to anyone!"

"I recently needed a new stereo after my old one broke so I went to Phase 4 Stereo & Electronics. They have a decent sized collection of merchandise and they allowed me all the time I wanted to browse the shelves. I eventually found what I wanted and ended up buying it. The price was decent."
