Wondering because my speakers are rated 110 watts rms and my amp is rated 85 and it pretty loud with the gain all the way down will me turning the amp all the way up still be under powering it? 2nd question. Are car door Speakers not the tweeters supposed to be playing vocals and audio? i know subs aren't just wasn't sure if this is harmful to the speaker woofer. |
