I would like to build a portable boombox with components I have on hand and am looking for pointers and suggestions.
I am a farmer and our farm had a big aiwa bluetooth speaker that played loud until it didn't. I have a bunch of hamfisted farm hands and want to build a portable speaker that can play loud and last a full day on a charge. I intend to mount this box on a stripped pressure washer cart. would be easy to mount a passive radiator in the down firing position.
I have
Soundstream D100 Amp
Soundstream D60 amp
2ea Dayton Dc160-8 6.5" woofers
2ea Tang Band 1320sj 4" drivers also 8 ohm
2 Dayton DC28F-8 1 1/8" silk tweeters
I like the idea of adding a passive radiator, but not familiar with which product. I like the idea of adding an active crossover so as to simplify the number of components stuffed into he box. I figure the tweeters could be dropped with minimal affect on the sound since the TB's play so nicely up high. A 16" by 21" box will fit nicely on the deck of the sprayer frame and I can go as high as needed upto 30".
I am open to using a head unit or a simple blue tooth receiver. I am unfamiliar with what battery and charger I should be looking for this project.
I am an experienced woodworker cabinet maker, have a full shop. I have wired 3phase machines and micro power controls, audio I am very inexperienced outside attending directed electronics snake pit course some 15 years ago.
All feedback is appreciated.

Cool project!
I’ve just purchased a couple of the tpa3116 Bluetooth 5.0 boards that are selling on epay currently. The ones I have are called ZK-1002, and ZK-1002L, are very similar, are around $15 each and make nearly 100w per channel from 24v. These newer technology amps are around 90% efficient.
You never mentioned what you have for a power supply, but two car batteries together would make for a decent setup.
My setup is a pair of bookshelf speakers that I put together for my daughter. I put one of the credit card sized amps inside one of the speakers, and left the volume set about half way, is plenty loud...
I would try a 2-way, using the bigger speakers and the tweeters, put a 3uf cap in series with the tweeter + lead and try it out in the box you described. You may need to switch + and - on the tweeter if it sounds off. Many commercial speakers are this way due to timing issues, won’t hurt anything but your ears if it’s the wrong way.
I’d save those Soundstream amps for something better.
