I ordered a powered JL subwoofer, one that had been on backorder everywhere else. I found that it was also 10% less than anywhere else. When I contacted OnlineCarStereo they offered an additional 5% on top of the 10%. It was a deep discount on an amp that is usually not discounted. Savings of over $150!
Great price! Easy ordering and listed everything that would fit my car.
I have been a customer for almost twenty years. Since my first purchase I have enjoyed amazing prices and great time shipping times. I think I have a had maybe two returns and everything else has been spot on. the only thing I have been disappointed about has been the availability of the head units, lately. other than that, Great Job and keep on supplying the good stuff.
The selection of products along with the price, you can’t beat.
Great price, really nice stereo. I didn’t need to contact customer service, but the transaction was flawless.
