Product Description
Speakers
4" Car Replacement Speakers - 50 Watts Of Power, Sold in Individually
BRS40
Before making your purchase, find out what type of speakers you will be replacing. You can simply measure the existing speakers and go from there. If you do not have any to begin with, a local Audio/Video shop can guide you with a few simple questions about your vehicle. Most of the time you will be able to drop them right in with little to no alterations needed. Pay close attention to the RMS power handling of the speakers you are purchasing. This is the continuous power that a speaker can handle without distorting. Your head unit will have to have the proper number of speaker outputs compared to how many speakers you plan to hook up to it, as well as sufficient power from the built-in amplifier. Sometimes though, a separate or external amplifier will have to be employed so that your speakers get the adequate power they need for optimal performance.

- • 50 Watts MAX 25 Watts RMS Power Handling

|---|---|---|---|
Poly Injection ConePolypropylene is a resilient and durable manufactured material. It allows for maximum flexibility that produces great sounding speakers. |
Foam SurroundFoam is a great material for surrounds in speakers and subwoofers. It is in general more flexible than rubber, providing a slightly higher efficiency. This also translates to better excursion. (How far the cone of a speaker linearly travels from its resting position). It generally lasts anywhere from 8 to 15 years under the right conditions of usage |
Stamped BaskedStamped baskets have better Resonant Frequencies. This means that the frame is able to absorb and transfer much of the energy produced by the speaker. It is more durable and harder to damage or break, good corrosion resistance, high thermal/electrical conductivity and retains strength at high temperatures |
High Temperature Voice CoilOur speakers are capable of higher or elevated temperature strength and fatigue properties that will increase performance and efficiency of heavy duty play time through lower weight and higher operating temperatures |

For a mid speaker this one is top notch at the price point. It’s rare to find single speakers so when I saw this I figured “why not?” I wasn’t in the market for anything top tier after market for a replacement after the factory speaker blew. The sound quality is miles above the factory speaker that came in our 2010 Nissan Rogue. The holes don’t match up and I had to cut the stock wire harness off and re-wire myself. But, not a problem. A few washers and some basic wiring knowledge is all you need to get the job done! After installing countless aftermarket speakers/amps/subs/tweeters in my personal vehicles over the years this one was a breeze! Say goodbye to distortion and that annoying crackle that comes with a dry rotted stock paper speaker! I’ve only had it in one day but if any issues arise I will update my review. 10/10 would recommend at this point in time though!
Sound is a bit quiet from what I expected but I was missing the center speaker on my 2006 grand prix monsoon system to begin with so I don't have a comparison. No buzzing or anything else using this.
Cover on the dash popped off with a pry from a flat head screw driver or dash plastic removal tool.
Fit was fine as well but did have a certain direction otherwise the cover wouldn't go back on.
Overall at least could have included 2 little wires to help lookup the unit.
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.
