I currently own a Kustom 2x15" 200 w RMS And a Hartke 210xl 200w RMS. But my Hartke amp gives 2x 350W RMS at 4 ohms The Kustom amp hasn't got enough power. Now I saw that eminence speakers (are also in trace elliot, bag end etc.) are very cheap(300W RMS) If I put them in my Kustom will that be enough? Or should they be over 350W?
