This might be a really stupid question, but, is there an easy way to add a second set of tweeters to a single source? Resistor in series?

I love the directionality of good stereo sound and I'm thinking about putting a second tweeter set in the rear. Basically the driver and passenger would each have Right and Left channels somewhere in the rear panel, headrest, or roll bar area.

Right now I have Polk 4" components installed. The 4" mids are installed in the panels ala Lucid, and the tweeters are not permanently installed yet (I have been trying them in a bunch of different places back there).

Current setup: The rear channels from the stock head unit are connected to a crossover. The crossover has speaker outputs for A) the 4" mids and B) the rear tweeters. How can I connect another set of tweeters to that? And to get even more tricky, I wouldn't mind being able to adjust the relative volume (one time adjustment--not like a balance control that's always available.)

Thanks in advance!

 

Hm, not sure I would want to add two tweeters to one channel... go for an extra amp ...

So what type of load will your amp see....

Tweeters will produce about 4 ohm impedance from you Xover point and up... put two of those in series your amp will see 8 ohms from cross over point on up and 4 ohms from xover point on down... I have no idea if an amp would handle that... but if I had to guess, I'd say sure, I don't see why not .

You don't want to have both tweeters on the same crossover, because that would change the filters parameters....

Why don't you e-mail your amp manufacturer and ask? Thats the best way to find out...

Thanks for the reply Robert! I actually don't have an amp (just the stock head unit).

I'm not very educated on this stuff so when you say you're not sure you would want to add two tweeters to one channel...can you elaborate, why not???


I guess I was thinking:

Currently, per channel:
-Stereo sees 4 ohms from crossover.
-Mid out of crossover sees 4 ohms from mid.
-High out of crossover sees 4 ohms from tweeter.

Possible (?), per channel:
-Stereo sees 4 ohms from crossover (same)
-Mid out of crossover sees 4 ohms from mid (same)
-High out of crossover sees 4 ohms from two 4 ohm tweeters in parallel (2 ohms) PLUS a 2 ohm resistor in series.

 

Wow running components off of the stock head unit... that's amazing ...

There is no way the stock head unit has enough power to drive two tweeters per channel and the woofers...

Since you can't really call the manufacturer, I would suggest tryin g it. I'm pretty sure you can't blow the amp or the speakers... The worst that could happen is you get really crappy sound.

Why would I not run two tweeters off of one channel? Simply for SQ (sound quality) reasons. Maybe, if I was on a budget I would try it... (I used to run 8 speakers off of one four channel amp back in HS, but the SQ wasn't that great. These days I'm serious about SQ, I just dropped $366 on front speakers and $270 on an amp... Not the most expenisve stuff out there, but I can't really hear the difference after a point.


Let us know how it works out...
