This full frequency amplifier adopts brand-new TI TPA3116D2 amplifer chip, which can offer 100W powerful output and 90% efficiency.Compared with other similar products on the market, it also uses a NE5532 buffer op-amp to achieve more powerful performance.Its super mini size can be easily hold by one hand, which will be a good match for your desktop.Power supply (not included, search ASIN: B074J81XRB to get one): DC 8-25V; at least 3A; higher voltage and current within the limitation would bring higher powerThe subwoofer version (search ASIN: B072KDNW3F / B071GL4C9V) is used for a subwoofer, while the full frequency version is used for a normal speaker (please note it is for one single speaker, not a pair. So if you have a pair of speakers, you should buy two full frequency amplifiers).

PA horn
CB to Amp cable (standard 3.5mm aux cable)
You’ll need speaker wire to run from the Amp to the PA and you’ll need to power the amp somehow. They sell an AC to DC power supply but if installing in a 12VDC vehicle you can run 12v to it directly but you’ll just need the barrel connector / plug end. You can buy those on amazon as well or if you have access to electronic scraps or spare laptop power supplies you can hack one off there and wire it to your system.
To use the speaker without the amplifier, not sure how loud it would be, probably not very because the CB can only put out like 12-15 Watts on PA, you can use this cable to hook the speaker to the CB
Hope that helps.
The problem with your setup is that any volume control you add to the lines will be based on DC resistance. It will decrease the power to that specific shaker, but the others will also receive more. If every shaker has the resistance turned up you may melt something.
A cleaner, if slightly expensive solution is splitting the LFE signal into 7 cheap mono amps, mounted to each seat.

Obviously spending $315 isn't ideal but it gives you the type of control you want with none of the drawbacks.
Something like this would work.
