im new to home audio and i have a yamaha htr-5390 7x115watts receiver and i want to build my own custom sub box and put in a sub 250-400watts rms. can i hook up the sub directly to the receiver? or do i need to power the sub with an amp within the box? do subs at stores come with amps inside them?

Most subs are indeed powered. The RCA connector for subs on the back of receivers is not amplified.

.

Buy a plate amplifier from the same source where you purchase the driver.
