Can I wire 2 8ohm tweeters and 2 8ohm woffers in parallel and run them off an 8 ohm crossover, or will the crossover get fried or something ?
Follow Ups:
Appreciate the advice/info. I just wanted to be sure that I won't destroy the crossovers if I experiment. Thanks guys .
The circuit will work just fine, assuming everything is wired correctly, but as corerosin said, your x-over points will be shifted by about an octave.
I've included a link that goes into great detail with regards to passive crossover designs and implementation. U can use your 8 ohm x-over component values to determine where the x-over will be when using a 4 ohm load.

That link assumes that you are dealing with first order passive filters, which is quite unlikely for a xover that comes in a high quality modern speaker. If first order, the high xpoint may move an octave up and the low xpoint an octave down, leaving a hole.
If second order network, the change may be okay, since only the shape of the slopes change, not the corner frequencies. It all depends on the xover.
I think U might want to revisit the link I provided.
It covers 1st order, 2nd order, 3rd order, bandpass, narrow bandpass, Zobel, Low Pass, High Pass, ETC. Pretty much everything a novice would need to gain quite a bit of knowledge about passive x-overs. One just needs to click on each link for further info on each topic.
Granted, these are just starting points and cannot be expected to provide results on par with seasoned/well established designers but it gives a good overview of the basics.
Cheers
Hello,
Just to let you know, I picked up the JL Audio F113's yestday... haven't finished setting them up but they don't sound too bad so far... especially for the deal I got locally, $2,400 each!

No. Because the inductors (L) and the capacitors (C) have their own impedance which will support the low or high pass filter into a specific load at eight ohms, when you substitute a four ohm load, two parallel connected eight ohm drivers, all the -3db will shift an octave both up and down. It will be a chocolate mess.
