If you want to know what's wrong, then find someone who knows what they're doing when it comes to speakers and amps. You need a multimeter to test those components and you haven't really described what is actually going on with your speakers. But that funky colored stuff on the circuit board is probably just old glue, hopefully

I'm away at school and don't have a car so I can't really take it anywhere. I've emailed the closet B-52 authorized repair repair shops, and sent them some pictures to see if they could help.
I've also always wanted to learn more about speakers and DIY, so I figured now would be the perfect time to learn!

I could probably take pictures tomorrow if that'd help..
well.. If that would help you help me! lol
I'd be surprised if it's a loose connection, there's probably something wrong with the tweeter amp on that side.

how much do you think it would cost to replace the whole chip?

An amp isn't a chip, it's a whole bunch of circuits and parts. Get the thing serviced and they'll tell you.

Careful fucking around inside amplifiers if you don't know what you're doing; big capacitors can hurt you pretty bad.

its $80 per hour labor + parts to get it serviced.. I think I'm better off trying to DIY this.. with the help of people who know what they're talking about?
how much would a crossover that would fit a Matrix 2000 cost?
would I be able to replace the whole board?
is a Multimeter as simple as touching different sides and whatever is wrong will obviously show?

if you don't have experience with basic electronics or even a multimeter don't mess with it or find someone who knows what they're doing locally and can diagnose what parts are messed up then you may
be able to order them through a retailer like gc who can see if they are available.
honestly nothing is jumping out on my in those pics, but hard to gauge without metering and smell etc
this is why i hate these all in one units

how does this look?
http://www.parts-express.com/pe/showdet ... er=290-634
specs line up.. well kind of.. the manual says the crossover is 2KHz the B-52 website says 1.6KHz and I'm pretty sure musiciansfriend has it at 2.5KHz
I figured this wouldn't be a problem
also the specs for the 2000 say 12dB/Octave, but the board is 18dB/octave HP and 12dB/octave LP but I figured this wouldn't be a problem because that just means that it cuts 18dB within an octave instead of 12.. right?
Thanks!

if your lucky the user manual may have the specs and part numbers in it (doubtful)
