Sony - SRS-XB43

Go for powered (built-in amplifier) speakers. I have transitioned from bluetooth speakers to stereo bookshelf speakers and I am not going back. I have Q Acoustics M20. And if you need more bass, wait a year or two, save some money, and go buy a subwoofer and connect it with the speakers. I have an SVS SB-1000. For a small to s-medium room you will never get worried about clarity, volume and bass again. If you go bluetooth you will always ask for more. However, if it is for outdoor use spend as much as you can afford to a JBL Partybox (for your budget, I'd recommend 120 or 320). Don't go to Sony (no bass at high volumes, I have a XB-43). Don't go small, as before, you will ask for more very soon.

Well this isn’t for the dash more like sitting in the back seat on its side, if you have windows down flips or charges won’t cut it past 30 mph. I also have xb43 but again probably too heavy for dash…just seeing them everywhere for great prices with Sonys new line out

I have 2 xb33 and xb43s each. The xb43 is great, but only available used and its a bit chunky & heavy. If you get one 2nd hand or refurbished for 100 it would be a great option. If buying new, probably the motion +, but havent tested it myself though, but reviews are good.

Sony xb43 is great. With a bit EQ you get neutral, detailed, full bodied and natural sound. No hissing. Try to get one used, as its not sold anymore.
