Well seeing as how you’re on a budget, I’d say to buy a Receiver. you can look them up on any electronic home audio website, (just try Best Buy to see what one actually looks like). They’re essentially home use amps. You dont need to go buy a high-end PA amp for this. Receivers can ranger from 50w to 500w. Check to see what your speakers are rated for, and set about looking for a reciever that has DOUBLE that power rating (because it will be powering two speakers). A lot of new recievers come with alot of “fluff” for use in a modern home audio setup. you dont need all that. If i were you, i would shop around second-hand stores and websites like craigslist, ebay, or the used section of an audio website
