Default Tweeter Install Question

I am installing new components in the doors of my TA. When I pulled out the stock tweeter I noticed there is a circuit board attached to the wiring. What is this and do I need it?

I'm no expert on car audio but I believe that is the crossover which is needed to cut the bass going to the tweeters. Hope that helps.

thats what I was thinking but I thought I remember reading on here that the amp has a built in crossover. IDK
Does anyone know for sure?
If it is the crossover should I just replace it with the crossover that came with the Components?

Check the sticky, I think the tweets are powered by the head unit and those would most likely be a high pass filter.

Bump!

Is there any way to adjust that filter? My Monsoon system sounds like it is missing some of the "high-midrange" frequencies. It sounds very "top-and-bottom" with nothing in the middle. None of the speakers are blown I think. Could this be it?

are you running the components off the stock amp?
it might not be giving the comps enuf power or they are diffrent ohm loads

get a 2 channel amp to run the set of comps

No, the impedance of the speakers makes very little difference other than a possible reduction in volume. Even that is unlikely as long as you use quality components because aftermarket speakers are generally more efficient - enough to make up for the 3dB drop in power cause by using 4-ohm speakers.

The tweeters in a Firebird are not powered by the amp so that certainly isn't the problem. Try playing around with the equalization to see if that solves the problem. I have also heard of some Firebirds having the high-pass filters go bad.

im installing components in the doors too and i've got a similar question. when im installing the crossovers, which wires should be hooked up to the audio in slots? if the tweeters arent connected to the amp, should i connect the stock tweeter wiring to the crossover and the stock woofer wiring?

If you are just replacing the speakers in a stock Monsoon system that still uses the factory amp then you don't need the crossover at all - the amp filters the low signal to the door mids and the already tweeters have a high-pass filter in the wiring.

If you really want to use the crossover, use it as just a high-pass filter. Connect the factory tweeter wires to the crossover input and the crossover's tweeter output to your new tweeters. Don't connect the crossover to the woofers in any way.
