AudioControl (www.audiocontrol.com) has good products, and they have a
4-way crossover, the 4XS. It will give you four outputs - high, mid,
midbass, and subwoofer. You can get them new on eBay for about $175.

Three-way crossovers are more plentiful and cheaper, and they'll do
what you want if you have at least one amplifier with a built-in
highpass or lowpass filter and a line-level pass-through. For
example, you could send everything from 300 Hz and below to one amp,
and set the amp's low-pass filter to 70 Hz. Everything from 70 Hz on
down would be amplified and sent to the subwoofers, and everything
from 70 Hz up to 300 Hz would be sent via the amp's line-level RCA
pass-through to your midbass amp.

I know that description might not have been very clear, but just think
of it as using a three-way crossover, and then running one of the
three outputs downstream to a two-way crossover. The final result
will be four discrete bands.

I need to replace an old dying Sledgehammer three-channel electronic
crossover in my car sound system, but am not really familiar with car
audio gear at this point. I want to upgrade the crossover to a
four-channel unit: Tweets, mids, woofers, and a fourth channel for the
sub. I have separate amps for each of these four speaker sets. I prefer
simplicity, reliability, and quality to bells and whistles.

Will someone with some experiental knowledge kindly offer their advice
on a well-priced yet quality unit that would serve this purpose nicely?
I'm on a budget, so not looking for audiophile quality gear hear (I
wish), but hopefully someone who has ideas for me knows the difference
between a polypropylene and a mylar capacitor at least. I have sensitive
ears!

Please also do me a huge favor and email me your answer as well as post
it in case I miss it here? sparky.seven(at)verizon.net

Thanks muchly! I miss my tweets and sub!
