I recently completed a halfinator build.
I wanted to add Bluetooth and a preamp in order to get the most out of the speaker. I wired these up today and when I tested the Bluetooth and preamp only the tweeters were producing any sound. Went back to original set up, still only sound outbid the tweeters. Swapped amp (tpa3116 mono) with a new one in case is wrecked the amp, still same.problem.
I didn't hear any worrying noises to indicate I damaged the hp10 drivers.
My amp has a startup plop, this has also been replaced by a click from the tweeter.
Anyone have any ideas? I really hope I've not ruined the hp10's but don't see how I could have.
