i know this is a dumb question but how do wire up another set of speakers if your head unit only has 4 channels (2 dash and 2 sail panels). i want to install a set of tweeters.

Most head units are only designed to have a 4 ohm speaker load. So if you were to wire them in parallel with the front speakers, it could burn up your headunit. You could wire them in series, where you take the negative wire from the dash speaker and connect it to the positive wire on the tweeter and then connect the negative tweeter wire to the head unit. But the best way would be to use a seperate amp for either the tweeter and dash speakers.

Why do you want to install the tweeters and where were you going to put them?

it also epends on what kind of deck you have. if it is a sony or cheapo, i wouldn't do it. i have a 2 ohm load on my panisonic deck on the front channels because of the tweeters, but i plan on adding anouther set, so that would make 3 sets of speakers on the front channels. my deck can handle 4-8 ohm, so i am going to run one set parrallel to the other, then run last set in series. this will equall out the ohm load to 4, which is what i started with. you could do the same, but since you are running 2 sets, you will need to increase your ohm load, so you dont take a chance of damaging your head unit.

good luck

i have the Panasonic 601u 50Wx4ch. im not sure where i want to put the tweeters but it would be along the dash somewhere. i want to take the 4x6's out and put in some kick panels. i've heard the difference between dash speakers and kick panels and kick panels just sound better.

Hooking up tweeters is completely safe no matter what head unit or amp you're using.

It's true that hooking a pair of 4 ohm speakers together will result in a 2 ohm load that can cook an amp. But... with tweeters you're looking at high frequencies where your amp makes virtually no power anyway. A 2 ohm load at 3khz and up won't even get noticed by the amp. As long as your tweeters come with a high-pass crossover, just go ahead and parallel them to your other speakers.

Some of the more expensive tweeters come with a crossover that sends only lows to the mid and highs to the tweeter. That way only 1 speaker would be playing at 1 time. But just splicing in a tweeter like Jim said will work fine too.
