If yours is not the size of the BRS35, there are other sizes available. **Q: is it important to use the plastic mounting ring?** A: Not if the speaker fits without them. I installed them in the front doors in my old Escort without them and they work fine. **Q: Is it a pair of speakers or just one speaker?** A: Just one at a time. So you really have to order 2 of them if you need a pair. Sold at unit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great sound *by G***R on May 4, 2026* Great speaker love the sound great price will get more for my other truck when ready ### ⭐⭐⭐⭐⭐ Good quality, perfect sound *by T***R on May 5, 2026* Good quality, perfect sound ### ⭐⭐⭐⭐ Works as Replacement for Job Rocker Max *by M***R on August 18, 2018* I used this 6.5” speaker as a replacement for the speaker from my Job Rocker Max with a minor modification. This speaker is about an inch less in diameter (I forget exactly). It still will seat in the cabinet, but the outer frame cannot reach to the screw holes to mount the speaker. I used those plastic mirror holder clips (normally used to mount a full length mirror to a door). Then I went to Home Depot to get longer screws (1”) to be able to reach through the plastic clip. I think I used six, but four would probably work. So $13 for the speaker and another $5 for mirror clips and screws and the unit is back in business. This assumes you already have a soldering gun to disconnect and reconnect the new speaker. The performance is similar to the old speaker. It seems to have a little less bass response, perhaps owing to the smaller size. The units are not about high fidelity, but rather portable music or amplification. I was glad I was able to save the unit for under $20. It probably took me more than an hour taking it apart and going for parts, etc., but I would have hated to just throw it away when I know it could be fixed. I looked at ION’s website for replacement parts. I could not find it. There was a phone number, but my guess was that this would be a hassle and more expensive. Maybe I was wrong, but how hard is it to list the speaker for order. I don’t know if my rating is fair. The speaker sounds like the cheap speaker it replaced. But that is a great value for $13. If you are going to be real picky about the sound, you shouldn’t be buying $13 speakers. ## Frequently Bought Together - BOSS Audio Systems BRS40 50 Watt, 4 Inch , Full Range, Replacement Car Speaker - Sold Individually - Amazon Basics 16-Gauge Speaker Wire Cable, 50 feet, Transparent - Kinter K3118 Texas Instruments TI Digital Hi-Fi Audio Mini Class D Home Auto DIY Arcade Stereo Amplifier with 12V 3A Power Supply Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/2391526-brs40-4-inch-replacement-car-door-speaker-50-watts-max](https://www.desertcart.kg/products/2391526-brs40-4-inch-replacement-car-door-speaker-50-watts-max) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-06-03*
