Biggest stereo bang for the buck mod
Can you buy this crossover at a Circuit City like store? Do you have to remove the head to install it? I love Bass and am interested in this...Thanks

I estimate that this will take about 30 minutes per door. What you are doing is installing a 220uF capacitor (a 150uF, 200uF or 270uF would work as well) in series with the mid-woofer. This capacitor creates a high-pass filter that filters out frequencies that are about less than 200 hertz to the mid-woofer, thereby reducing the amount of bass coming from these speakers. This allows the bass control to be raised by about five to seven increments to get the bass from the subs at a higher volume while not overloading the mid/woofs. As I stated before, this little modification does wonders to the low frequency through the lower midrange frequency band. It was enough of an improvement for me to not go out and purchase an entirely new system. Since it will cost less than $5 and only about an hour total, it really is a great modification. You can purchase the caps (2) at Radio Shack for less than $2 apiece.
This is the procedure:
1. Pop off the panel with a screwdriver.
----> Use a small flathead screwdriver and with a little finesse, the panel will pop right out.
2. Reach in and disconnect the rear connector (the one with two wires, not five!).
----> Squeeze in the two tabs on each side, and pull the connector downwards. When it disconnects, there is enough play in the wire to pull it out of the door panel several inches. You will have to pull back the black cloth sleeve that protects the wires inside.
3. Install the capacitor.
----> I have two different procedures for this. Cut one wire and splice in the capacitor using either 1) wire nuts or 2) crimp connectors.
----> The capacitor can be wired in series with either the red or the black wire. It doesn't matter.
----> Capacitor values in this range are usually polarized. This means that one end has to be connected to the more positive voltage side of the circuit. In our case, this is a don't care and it doesn't matter which way the cap is oriented. This is because there is no DC voltage level at the amplifier output (actually there is always a few millivolts of DC, but never enough to worry about).
----> In summary, the capacitor is put into series with either the black wire or the red wire, and it doesn't matter which way the cap is "pointing" in this series connection.
4. Reconnect the plug and pop the panel back into the door. Done! Enjoy your great "new" stereo!
For my tastes, Before the mod, I usually had the bass control set at -7, -8 (or sometimes even -9) to prevent the front speakers from over loading and distorting from too much bass. After the mod, the bass can be put all the way up to around -5 to about +2, depending on the material.
I will state that however easy and safe this procedure is, I am not responsible for any damage incurred by anybody performing this to their Crossfire, either to their person or to their vehicle and/or other property.
Good Luck and have fun!

I bought capacitors from Radio Shack. They look exactly like the ones in the pics from pelked.
They say:
220uF
Electrolytic Capacitor
Axial leads
35WVDC maximum
Thank you guys.
EDIT - I see that there is a post with the capacitors I bought that says 'Do not use these.' Guess I missed that in the 149 posts. I'll order a couple from Amazon.com.

Will this modification reduce or eliminate the irritating rattles that are produced from the passenger door when somewhat bassy music is played?

So this basically just sends more bass to the subwoofers. I reached behind the seat when bassy music was playing and felt almost no bass coming from the rear speakers...

The door speakers come alive with midrange as well.
It is a great mod at any volume. I used a set of 330uf capcitors.

WOW who would have thought a couple of bucks could make such a difference. After about 10 min in each door, I took her for a little spin....dang I didn't want to get out of the car! This system sonically is now the equal of the Alpine/JL/Polk set up in my Dream Cruiser. Only difference was I spent about 6 bucks instead of $1,000. Pelked1 you're the bomb!
I put in 220's and the sound is 200% better at mid volume, 300% better at high volume, but only about 112% better at low volume. I think I might try a slightly higher capacitor number of 250 to add a wee bit more warmth to the mid range. But I love the subs now....it just gave my Crossfire massaging seats...LOL
Thank you, Danke, Merci, Gracias, Mange Tak, Pelked1!!!!!!

I tested 220,270,300 and 330 caps using an audio test CD and determined to MY satisfaction that this was the best value to use. It seems to cut off the doors at 180 hz.
JMHO you understand?

Save one of those 270uF caps for My New Roadster in the Fall, is my Credit still good from the Spring Meet?
BTW, can I put you down for a Return to the Dragon?
Hope you will be there again, with your Mrs, & take care of your back this time. (or you could Ride the Dragon Shotgun with me & I'd give you a Great back adjustment, quicker than a wink

I'll even make some more copies of the CD for folks.
