Review on Herdio 4 Inches Marine Box Bluetooth Speakers - Powerful 100 Watt Waterproof Stereo Sound System for Boats, Golf Carts, Jeeps, ATVs, Trucks, and More! by Kantrel Tunstill

Upgraded to a few stars for the original rating because of excellent customer service. They sent a replacement even though I didn't ask for it and corrected the misleading description. Below is most of the original review. Most of it is still an accurate description. The misleading description is only passive speakers with no active speakers. They come with a very small, lightweight, foreign language Bluetooth amplifier. The speakers themselves aren't that bad (with a better amp). They have clear sound but no bass. The amp worked about 30 minutes after I installed it. It didn't really bother me because it sounded bad anyway, just not enough to drive the speakers. I would return it, but since I did my best to install the speakers and I installed the amp in a place where it could overheat a little, that's partly my fault. I'll just write that down. I bought a new and better amp. At the same time, the speakers sound reasonable and loud enough. I could get speakers without a bluetooth amp for half the price. I would definitely not recommend those claiming to be Bluetooth; However, the speakers themselves look good and fit well in the corner. They're not great, but they're not that bad. Here is the most misleading part of the description: Active-Passive Speakers: 4 inch 2-way full-range stereo speaker with 1 PEI dome tweeter, main speaker, built-in negative speaker. in 2 channel amplifier brings you stereo sound effects.
