Customer Reviews
Decent purchase, few issues
I ordered a set of component speakers and a wiring kit. The speakers arrived in about five days, which was reasonable. Everything was packaged okay, though the speaker box had a small dent. The wiring kit was fine. Customer service was helpful when I called about a question on the amp rack I was also considering, but their hold times were a bit long. Overall, I got what I needed at a fair price, but delivery could be a touch faster, and phone wait times could improve.
Smooth order for a new head unit
I decided to upgrade my old car stereo and went with a new head unit from Low Hertz. The ordering process on their website was straightforward and easy to navigate. I found the specific model I wanted without any trouble. Shipping took about a week to get to me in Arizona, which was within their estimated timeframe. The unit arrived well-protected in its original packaging, and everything was included as described, even the antenna adapter I needed. Installation was pretty standard, no surprises there. I didn't need to contact customer service, so I can't speak to that, but the overall experience from browsing to installation was positive. I appreciate that they carried the exact model I was looking for.
Subwoofer enclosure arrived quickly
Ordered a subwoofer enclosure. It came fast, like 4 days. Fit my sub perfectly. Good quality for the price.
Good amplifier, fast shipping
Just got a new car amplifier from them, and it came super quick, like 3 days to my door. It was well-packaged too. Install went smooth, and it sounds really good with my existing speakers. No complaints here, I'd definitely buy from them again when I need more stuff.
