Hey guys im new to the whole audio world , and i found this vintage nikko alpha 1 540 watt amp. I want that to power my front speakers sepretly i have an rca jack from the amp to the area that says pre out from front and left. but im not sure if its doing any thing there is a red light on the amp but there is no power button on it. although the amp does get warm. so do you guys think i have it hooked up right ?
