How to create a simple amplifier from scavenged car stereo parts to put sound into a backpack

Step 1:

I didn’t want to spend a lot of money on parts, so budget wise most my parts were scavenged from a car stereo a friend was going to throw into the trash. I made this so I could have a more portable and convenient boom-box type back pack.

Like this scavenged TDA1558Q from that stereo. (On the heat sink)

I did something like this before by taking the set up out of a gaming chair with the speakers, inputs, and volume control, that was nice but it didn’t have the bass that I really wanted from a portable stereo. My improved version has the bass that I was looking for and has the volume control from the audio input device (i.e. Mp3, ipod, iphone, etc.).
How to connect bass, treble and vol knob on this project?
Cool man. How u find it.<br>can you prepare the same is but with bass, treble and vol knob connected.<br>thanks<br>

I'm glad you asked, it actually sounds really well, better than you would originally expect, i will soon find a way to add a video or a link to a video so you can hear it, thank you for bringing that to my attention
