OEM Amp Pics (Premium vs. Shaker)

[dgreene]

I was curious what the difference there was between the Premium 9 Speaker and Shaker "12" Speaker OEM amplifiers. As I expected, NOTHING. Just programing is changed. Boards have identical serials, components and paths. Here are the photos of the units opened.

Do you happen to know how many watts per channel the amps put out?

Nice work! This "Shaker" upgrade is now proven an even bigger rip-off. Glad I didn't get it.

Yes, sad state of affairs.

No, however I can tell you that the speakers I have seen are lower wattage units. Mine had the 9 speaker premium with 4 ohm units @ 25 Watts. I read that the shaker system used 2 ohm speaker units so wattage would theortically increase some.

Yes, sad state of affairs.

I can attest however that the sound programing is different between the units. I am curious if the line sub out put (on pins 1 and 2 of grey cable) is still enabled on my premium amp. I am trying that next and will report back.

All I can say is this, a 9speaker amp, and 12 speaker amp.

I hooked my JL subwoofer up, the mono d amp, wired directly into the clips that go into the amps.

9 speaker amp- would not produce any signal for my subwoofer

12 speaker amp- played beautifully. So soemthing IS different, because the 9 amp had zero sound, all wiring the same.

I had a 9 speaker car, had to get an amp from 12 car to enable the sub to work/get signal.

Additional note. I put in the 9 speaker today just to take a listen. Night and Day difference. The Shaker amp albeit looking the same certainly has something different programmed into it. Lots of compression programmed into it. And the sound stage is geared towards the front passenger side. Very odd sound.

What did I miss? I love learning. I would love to know what is different with the boards.

I'd love to know the difference as well. I have 2019 that came with the premium 9 spkr system that I changed to a shaker setup by adding the 3 wires to the harness, changing the amplifier to "CP", changing the speakers to the factory 2 ohm units and installing the oem sub. Anyway, it sounds really good and is loud enough but the oem 9 spkr setup was considerably louder with its matched speakers, though there wasn't much bass. The oem amp ends in AB which I've never seen before. If it's possible to make the AB amp work instead of the CP amp I'd love to.

I'm also curious about your image. Though, thanks for sharing them.
Was there any heatsink on the white chips on the left side of your image? I'm just guessing that it's two identical copies of multiple-channel amplifier chips, and the white residue on top is actually from silicon grease for heat transfer, which is left there. If that's the case, then there are two inductors and capacitors on the side of them, which should be first-order x-over implementation.


Do you have a better image that shows the part numbers?
