Your first link doesn't work. Your second link provides no more than a frontal view of the speakers, which is rather worthless since I need specs for the system.
You don't say what radio you are using and that is rather crucial since the amp must drive three speakers.
Without any more information than you've provided, I would say try a series/parallel connection; https://www.google.com/search?q=speries%2Fparallel+speaker+connection&rlz=1CAACA J_enUS705US705&oq=speries%2Fparallel+speaker+connection&aqs=chrome..69i57j69i58. 10861j0j1&sourceid=chrome&ie=UTF-8#q=series/parallel+speaker+connection&*
That will provide a lower than normal impedance load which your amp must deal with. If the radio is not overheating when in use, it will likely survive.
That's the cheapest way.
One issue with a series/parallel connection is, should one speaker fail, all speakers will be effected and will not work.
Better is to buy a small switch box with a built in load resistor which provides a bit of "protection" for the amp; https://www.crutchfield.com/p_190SS4/Niles-SS-4.html?tp=2997&awkw=75619818985&aw at=pla&awnw=g&awcr=47439082225&awdv=c&awug=9026910
That's about all I can do given the lack of information provided.
