OK , Hi all ..
This my First Project in Instructables ^_^
I am from Indonesia , Here was held 26th SEA Games 2011... GO Indonesia !!!


Ok check this out ,
This is 10 watt amplifier and LoudSpeaker,
Let me tell you how I make this thing

Part List :
# acrylic
# Loudspeaker
# Some Wire
# 9Volt battery Connection 
# Unbalance Jack Female
# Power Jack Female
# Potensiometer
# Capacitor ( 2.2uF ; 470uF ; 100uF ; 0.1uF ; 1000uF )
# Resistor ( 220R ; 2.2R ; 1R )
# IC Tda2003
# Heatsink

Step 1: Build Loudspeaker Box

Picture of Build Loudspeaker Box
Tools I use :
# Saw 
# Drill machine
# Melting Glue

I think the result is not bad , 
Ok its bad but not really , LOL

Step 2: Core Part - Tda2003

Picture of Core Part - Tda2003
The TDA2003 is a cheap amplifier that is designed to run on single rail power supplies. It has many applications (including in car systems if you do not need to show off down the high street with your subwoofers!) and is protected against short circuits in almost every way you would think them possible.

wt abt output den?
Ghild.Zero (author)  DMRPUKU9 months ago
Ooopsss , I am sorry, man ....
j9 is for output (loudspeaker)

j6 is for power input , it has 2 ways : 9v batery (using 9v connector) and adaptor ( using Female jack connector) . They are paralel .

wats j7,j6 n j9??
Ghild.Zero (author)  DMRPUKU10 months ago
j7 for input audio
j6 for input batery 9 volt
j9 for input 9 - 18 volt

Here is it , hope can help you :

The Schematic :
The 3D :
yup got it!

hey.wat does dose j1 j2 j3 j4 c1 c2 nd ol stand for..........???? help in really need of dis
Ghild.Zero (author)  DMRPUKU10 months ago
j1 j2 j3 j4 j5 is pin of IC tda2003
C mean Capacitor , the value of c1 is 100nF(no polarity) and the value of c2 is 1000uF

stil confusin!
nyways how much value does the pot hav?

Ghild.Zero (author)  DMRPUKU10 months ago
for the value each component you can look at the schematic picture

ok, so you said a 12 volt would make this sound better. it sounds interesting but I would need some help, for the power, do you think I could just use a DC wall wart? or would it have to be AC? (sorry if this is confusing, im kind of new to electronics, i've only been working with them for about a year now) and this project seems like a great idea since I love working with speakers and I always get lots of request to build some for people! (i've gotten a request for a mini ipod speaker for $20!)

Can you please tag which capacitor and resistor are which?? I really want to make this however I can't work out where each resistor and capactior go, and how many of each I need. Good instructable otherwise :)
Ghild.Zero (author)  NatDaGamer1 year ago
Terima kasih NatDaGamer ^_^

Please check this
What resistance potentiometer should i put? 10Kohm or 40Kohm?
Also i seem to have a problem with huge distortions on low volumes. Could it be because of the potentiometer being 10kohm?
Nvm solved it. For anyone wondering i had 2 4ohm speakers wired in paralel. I fixed the distortions by connecting them in series.

Also that what are Cx and Rx for in the datasheet ? there is no description of the circuit do you have any link ?
usbg3rd2 years ago
nice instructable and easy to build too but i have few questions

can someone help me i built it but the output was distorted not too much but it was enough to annoy some one (when the output is at max volume) at lower volume its fine enough.
and when i short the capacitor C2(1000uF) the output gets stable and distortion is reduced (at max volume) but gets distorted at lower volume .
strange but true
anyone who has built it can try himself and what is the solution for low distortion at max and min volume simultaneously.

can you modify it to run on 12 volts or does it need 18 volts because i would like to use it on a robot that only uses 12 volts also what is the maximum wattage it can run
Ghild.Zero (author)  asmith4332 years ago
12volt supllay is fine ^_^
what is the largest speaker you can run (:
dihnen2 years ago
I appreciate your modularity, use of standard connectors, power, simplicity, and portability. That is really quite an excellent build.

i have a... maybe stupd question... is it posible to put 2 or more of those in a row?
Ghild.Zero (author)  ag6219942 years ago
I suggest you to build a stereo amplifier , it is more efective and efesien
eli2412 years ago
hey bro.. can u upload your pcb layout?
Ghild.Zero (author)  eli2412 years ago
Yes No Problem

i think this is a stupid question but can you tell me where to put the Potensiometer in the circuit?
