part #7: An Amplifier

 

you can use a normal aftermarket amplifier, or this kind of amplifier kits, or skip the amplifier step by still using you stereo head unit in AUX mode

TDA7850 Amplifier 4-channel BA3121 Denoiser For Car CD/DVD Audio AMP DIY DC 12V

EBAY LINK

 cost: 32$

 

the reason for getting this kind of amplifier, is because it’s cheaper then a standart car amplifier, and it can be connected to the ISO harness directly, also it has 4 input, so we can directly control each speaker input using the arduino, see the 4ch volume control unit i made for it..
