    I have a Kenwood D710 I'm my van. Right now I hooked up a Kenwood speaker to it, but man it still sounds like the folks are underwater. When I had it hooked up in the house I used a book shelf speaker and it sounded great. Any recommendations for a mobile speaker that will actually sounds good?

    Used Motorola mobile speakers are hiqh quality, designed for voice communications and essentially indestructible with a 3" cone. You can pick them up at hamfests or on eBay for generally around $10-$35. You have basically two choices: Rounded and square. Sometimes you find them surplus in piles.

    They work well in the shack, and are a noticeable improvement over the tiny built in speakers of radios. Additionally, they can be pointed directly at the operating position; improving reception. For multiple radio operating, separating speakers helps quickly identify which radio the signal is coming from. I've got half a dozen in the car and shack in use for over 25 years.

    Caution: All car speakers should be mounted so they do not become missiles in a crash. Motorola speakers are particularly heavy (reduces vibrations).

    I have several of these cheap speakers from Amazon:

    They work very well for me under the seat; but I am 36 years old and still have my high frequency hearing. I have older friends who mount the same speaker where it can be heard directly.

    I could be wrong, but I can't image you really want a speaker for the radio in your car that sounds like a bookshelf speaker. For one, it will not sound at all the same in the relatively noisy environment of your car as it does in your quite house. All of that extra frequency response that makes it so pleasing indoors only makes what you are hearing less intelligible in the car.

    There is not a lot of practical variance when it comes to sound quality from a 2 or 3 inch speaker in a tiny box. Whatever you do, don't spend something like $100 on a solution. You will just be wasting money.

    Try to mount a small speaker just behind your seat at near head height so you can hear it without a lot of drive volume. This mounting location is usually not objectional to a passenger when driven just loud enough for you to hear.
    I use a small CB unit cabled under the seat to the radio.

    I have a bunch of new and semi-new Motorola speakers. They sound great. Let me know if you want one, I'm selling them semi-cheap.

    I'm with William and Eric, I've tried about all the speakers out there in everything from sports cars to farm trucks to tri-axle dump trucks and for the money the square Motorola speakers are the best sounding and toughest speakers you can find. Luckily I was able to rescue several from a company communication rework project and I use them in my vehicles and both shacks.

    The D710(a) should be similar to the TM-D700(a) that I once owned. For that radio, I found that the noise switch on the Yaesu SP-4 speaker ( discontinued, yet may still be available ) was great for that mobile chat as distance to the repeater managed to cut the signal. I would also agree that some of the older Motorola speakers had great sound. The only issue with some of these Moto speakers was the built-in amplifier. Many made after 2004 had an amplifier included inside the housing, meant to be powered up by the radio that was connected. If you open a Moto speaker case to inspect for this, be aware that: 1. The case screws can easily be misplaced, sometimes getting stuck to the magnet on the back of the speaker assembly. 2. Reassembly without damage to the plastic means getting everything lined up properly- including the cable. A rag can help keep the 'face' side from slipping when installing the screws. 3. Try not to misplace the pair of mount-to-speaker 'thumbscrew' topped bolts. Regular bolts will work- if they are of the correct length.

    I have great sounding speakers in my F150 Truck using the KENWOOD KES-5 Two Way radio Speakers.

    I mounted these on top of a cut off 2x4 wood and this slips into the drivers door slot. These are available from AMAZON

    I am feeding these two speakers with my ICOM 706MKII and Kenwood V708A radios...

    I like them mounted on left side of me in my truck... Takes away a lot of the Ham Radio sounds away from the wife...

    I have been operating mobile for decades . . .

    All I have ever done is use the car's EXISTING Door Speaker (on the driver's side)

    It's usually a good speaker . . . it's in exactly the right position . . . and it saves having to mount an extra speaker somewhere where you can hear it properly.

    You can either fit a little switch that switches that speaker between the Car Stereo and the Transceiver (as in the photo of my 2m rig on my QRZ page) . . . or if you have a radio that gives 12V output when on (to supply an electric aerial) you can use that to drive a small relay to do the switching automatically. (that's what I do in my other car, for HF mobile)

    Another Kenwood KES-5 fan. They are also super loud. A bit warmer than the Moto speakers, not as harshly communications grade.
