Hi, I just replaced the speakers in my car, and am now realizing how weak my stock head unit is, so I'm looking to replace that too. Looking around online I found ST Electronic's TDA7560. From the datasheet it's a complete 35x4 amp in one IC. All you need is to feed it power and the signal, and it does *all* the rest for you. Just wondering if anyone has had any experience with this chip, or any of the rest of ST's TDA738x series. Here are all of the series and the datasheet:
