Okay I have 4 4-ohm tweeters (65w rms per tweeter) ran parallel with my rear speakers (right and left) causing a 1.33 ohm load based on some calculations I wrote down. the tweeters are actually tapped into the speaker wires already in place. with the rear speakers. I have read that having that kind of power ran through tweeters will fry them. What I wanted to know is that if I ran the tweeters parallel but switch the connections would that cancel out the tweeters and rear speakers? if not, what load would it be ran under in that configuration?
1. Is your amp 1-ohm stable? 2. Why on earth do you have 4 tweeters on rear channels? 3. You can make a custom crossover that will prevent them from getting clipped, but realize that you're going to be drawing *equal* power from your rear speakers.
How do you mean "switch the connections"? Reversing polarity? All that will do is put them in opposing phase.
2. Installer at audio shop ran them parallel with the factory speakers and positioned them where I could get more clarity. I got better speakers now, but don't want the tweeters to go to waste.
3. What would the opposing phase sound like on tweeters? also what ohms would that set up run in?
1. 1.33-ohms is well below 2; you will fry the output transistors. 2. Why not just run 2 tweeters? Don't risk everything else for $50 worth of equipment. 3. Opposing phase just buys you some microseconds when it comes to timing. You're still at 1.33 ohms.
How about running the front speakers on one channel (front speakers are 35-40w rms), run the tweeters (just found out that they are 20-65w rms) on two separate channels, and then run the rear speakers on parallel on one channel?
Basically, it would be 8 speakers on a 4 channel amp running 2 ohms. I just want everything I have to be used.
