Plan: Remove the old 6”X9” Pioneer speaker, Fit 6” speaker (JBL GT5-652) and 4”X6” speaker (Boston FX7)

Simple Cross-over Circuit:


The Speakers :


Rear Parcel tray after Alteration:


Covering Finished (Sorry poor picture!!):


Finished Tray and speaker installation:


Now waiting for the Capacitor And Inductor to Check an finish the Installation .

Pardon me, How different is the sound output in comparison to 6x9s?

What is the round thing below the brake lamp in the last pic?

If it were me I'd have kept the 4x6 speakers as fasr as apart as possible to retain some degree of channel seperation.

what is the woofer between the 2 4x6 mids anyway?

BTW:
a. 3mh air core will be huge so get a soft iron core for the 3mh.
b. to make 200uf get 2 470uf electrolytic caps and wire them back to back (series) then get a good polyester or polystyreene or teflon 1-2 uf cap and bypass the series (470+470) combo.

hope this helps.

This is just an inlet for the bass to travel if the subs are placed in the boot. I have a similar arrangement and it is effective.

where did you get the inductor

[sreejeshmp]

Thanks for the suggestion.

Just now I finished the installation; I used two 100 uf Capacitors Parallel for the Boston 4X6”. I didn’t get the 3mH Inductor so for now I directly connected the JBL 6” parallel to the 4X6”.The working is better then My old 6”X9” Pioneer 400W coaxial 3 way speaker. It gives good quality sound for 80’s Malayalam songs (Which I hear in low volume) . But I have to set up the Low pass filter for 6” woofer then only I will get the perfection which I planed.

sreejesh, ideally if you are using polar ( having + and -) electrolytic capacitors in a crossover, you need to connect them in opposite polarity to make them bipolar.

If your design calls for 200uF, I would use 2x470uF in series ( and in the opposite polarity)

thats what I did

I'm still looking for inductors. I dont think anyone makes them. We'll have to literally roll our own

I think it was mentioned earlier only sreejeshmp finished the install before he read our posts.

Thanks for the bipolar set up I will Change the capacitors polarity.

Hi greenhorn,

I found few 3 way cross-over networks available in my place which are locally used for speaker cabin manufactures they use a woofer, mid-range, and tweeter, I am planning to use them but the problem is I can’t find the Impedance of the Inductor they are Using the shop owner told me that it gives good result.

Any input?? .
