X20

+1 for the w-king x20, I have a pair of those and they're great

I don't think the speakers you have in mind are powerful enough for your application. I would at least choose a speaker from the boombox class, such as the W-King X20, the Tribit StormBox Blast 1 or 2, or, if you can still get it, an EarFun UBOOM X, which offers the best value for money. The Soundcore Boom 2 Plus/Pro is quite light, but I deliberately put it at the bottom of my list.

The W-King X-20 might be of interest to you. It offers a higher maximum volume, but is significantly heavier than the UBOOM X (7 kg compared to 4.15 kg). If I were you, I would try the UBOOM X. Its performance should be sufficient for the interior of a car, and its audio quality is superb. This thing is really fun. And if that's not enough, a second speaker would be a good way to increase the output, while also giving you a stereo setup with room-filling sound and a wide soundstage. I would say that a party speaker is excessive for use in a car. It's blocking the entire back seat. But you have to decide that for yourself. I would consider the ONN party speaker to be on a similar level to the W-King T9 Pro.

The X-20 weighs 7 kg, making it almost 70% heavier than the UBOOM X, which weighs 4.15 kg. Its dimensions are also significantly larger. Whether the slightly higher maximum volume of the X-20 is worth it is up to everyone to decide for themselves. For me, it's not. I often use two speakers for stereo sound outdoors. Transporting both of my UBOOM Xs is already a sufficient hassle. I didn't want to add even a slightest bit more.

I own the x20 also and can tell ya right now .. in my opinion anyways... that it absolutely wipes the floor with the soundcore boom 2 pro.... I haven't owned the plus version but I bought the boom 2 pro at Walmart few weeks ago for 197.99 and just not at all impressive to my ears. But those style a speakers are on a different playing field than this boom 2

I know i love the x20 ... i also just returned a zealot s89 cuz it had multiple defects so can't comment on that speaker but the wking with the app and super fast charging it's a beast and it does not distort or lose its bass at high volume .... can't rec that speaker enough in my opinion

As someone who's owned a shit ton of speakers since 2018 id go wuth something from wking or tronsmart..... my at home speakers are set of jbl partybox 110s ive had em since their release but ive sold the jbl boombox 3 wifi ive returned the jbl charge 6 and flip 7 ive returned the sony ult 5 ive returned the bose max why cuz of wking and tronsmart .... the wking d320 smokes the flip 7 in every way besides deep bass bit the kicker is thats only if ya play the flip 7 at 60 percent or less volume .. anything over that and sound goes to shit which is why I returned it and same goes for the charge 6 plus both their battery life is way overrated if ya add any bass and treble and play em at 60 percent or more volume the battery life is easily cut in half plus ya can't make or take calls with them..... but also the wking x20 is still for price of it and sound and features its literally unbeatable still today and that speaker is why I sold the jbl boombox 3 wifi I think only jbl speaker that is worth its pricetag is the speakers in their partybox lineup those speakers are bad fn ass but also tronsmart man have they ever impressed me since I got my first speaker from them.. the tronsmart mirtune h1... right away bought a 2nd for tws... thats why I returned the soundcore select 4 go the bose micro 2 and the jbl clip 5....but I now also own two of their trip 2 speakers and the fiitune x30 but for a shop id easily buy their bang 2 speaker..... sorry for long rant but I will never buy bamebrand speaker again after now owning multiple speakers from wking and tronsmart ..... both are becoming what soundcore used to be before they focused on marketing over sound but theyre producing speakers that cost consumers a lot less and sound as good or better along with having phenomenal accompanying apps to fine tune then with eq and update them. Soundcore got lazy and focuses too much on gimmicky shit and marketing ... their almost 10 yrs old motion + still smokes everything they've released since then for sound quality especially their 300 and boom 3i.... back then they focused on actual sounf but def arent doin so anymore so if I was you for smaller speakers id go with the mirtune h1 or the trip 2 or d320 or lil bigger and id go wuth the bang 2 or wking x20

Here's the thing . You could get the og tribit blast for anywhere from 140 to 170 and smoke this and everything else .... or spend tad more or wait for a killer sale and get the wking x20 which smokes literally everything including the hb3 ... oh did he say x20 better than bb3 ?? F yes I did and the thing charges with type c up to 60 watts so ya can charge it on the go.. . Crazy how the x20 is still kickin ass over almost everything and its been out for lil over a year

X20 gets extremely loud and great bass. I cant imagine needing more than this

after some extensive research went with W-KING X20, which I got on Temu from the official brand store (after coupons it was like $160, currently on amazon for about $220 with a 40% off coupon). what eventually convinced me after going back and forth on all suggestions was price and this video: [https://www.youtube.com/watch?v=cXNZ6SPZ7tI](https://www.youtube.com/watch?v=cXNZ6SPZ7tI) and it was on the list of suggested speakers for loudness, plus has tws so could eventually get another one :)
