T-Amp Tripath TA2024 2x15W Audio Digital Amplifier Board 320-600

I got 2 of these for an inherited mini-van that had only an AM/FM cassette deck; one for the front speakers, one for the rear. I just plug my phone or MP3 player in and get good sound out. Get a good pot for the volume.The sound was very good on the workbench in the garage with good speakers. The sound is OK in the mini-van, but the sound was even worse with the stock radio. (It's not these amplifiers but the speakers in the van not even coming close to what's at the workbench.)
