First of all thnx to all those who like my project
@ Guns On circuit boards for speaker output there are normally three soldering points one wire from both speaker cables attach to one point for that i have combined two wires from each cable this is same phenomenon as in ur headphones pin i.e. three points for two speakers as shown in pic
@ razaksyed yes boss ur idea is good i ll try if capacitor can improve the quality otherwise the quality is very good as compared to modulator but u have to solder the wires precisely at right place.
@ devilz_apprentice Sir to locate the sound out put points one must have a little knowledge about circuit boards. If there is any input / output port on ur FM Modulator the sound output points will surely be around that port and u can search by using a speaker with cables by touching the points on circuit board and about close up pics i only have the pics which i have uploaded coz at that time i was so much involved in my work that i forgot to take complete pictures.
