I'm starting to design my audio system, which will be run from a carputer. I need to make sure I have a high quality audio source to start with, and am lookin at Sound Cards which have digital or optical out signals.

Are there car amplifiers which support an optical in / digital in signal?

Would be awesome if there was a 4ch amp which had 5.1 optical decoding, and could output the second 2 channels to an attached second "slave" amp.

Or am I over exaggerating things, and analogue signals from a high quality PC sound card would be fine to send through an amplifier?

Edit : I've found one 5.1 amp, Alpine MRA-F355, with optical in and full dolby processing!

I'm still looking for an amplifier which has optical-in...

The Alpine MRA-F355 does, 5.1 channel dolby decoding, 50W x 5 channels, for around $700 (RRP is $799)

Are there any other amplifiers which have optical-in and digital decoding?

We often use the Focal Dual Monitor amplifier (it has inbuilt DSP etc) as a master and the Focal FP1.800 as a slave. However the output from master to slave is analogue (RCA). It is an optical input to the DM though. :P

Wow, the Dual-Monitor looks nice, 2x250W of power. Also digital control via USB, not sure exactly what you can control...

So can it accept a 4-channel digital signal, and decode all 4 channels. 2 amplified internally, and the other 2 channels are analog (RCA) output? Or is it only decoding 2 channels? The PDF wasn't too clear...

Any idea on RRP?

To be honest I haven't experimented beyond two channel audio. I'm not sure what the amplifier would do if you feed it a 5.1 music format. It only has a two channel slave output though so you could not run another bunch of amplifiers for surround, center and subwoofer channels.

They retail at $2999.

    • So my rb is finally having more problems. 2 issues here but I'm here to just to mainly discuss the rattle noise. The other day when I turned on the car and when I take off or go in reverse, there is a temporary rattle noise but when I cruise, boost, idle it's completely fine no rattle whatsoever. I've also done all the servicing, all the health checks you can think of and it all passes with flying colours.  Also the rattle doesn't increase with rpm, it's only at a very certain rpm (slightly above 1,100rpm). My other car also has the same issue every once in a while. Changed the oil recently, no difference. Even took my oil to a lab and everything was quite good surprisingly. Timing belt changed a while ago to. Had the car on the hoist and can't see anything obvious. Tightened a couple of nuts on the exhaust manifold a couple of months ago. 2 different clips uploaded. One of them was supposed to another issue but I'll save that for another time. Thought I'd see if anyone had this same noise before, it's a bit hard to diagnose while it's intermittent. If I'm not mistaken, I think I had this a while back but can't remember exactly. I was thinking if it's doable I'll get someone to hold the throttle cable at 1,100rpm and hopefully it replicates the sound. rb25det rattle only.mp4 rb25det slow start + rattle.mp4
    • Haha wow, yes they do! Will sort tomorrow.
    • Yeah I’ll know when I take it for a test drive and I’ll double check the turbos as well when I have a look at it again.  Just thought maybe they might have done something in the head cause it looks like they’ve taken off the rocker covers 🤔 Thanks for your info! 
    • As Duncan mentioned it's likely a remapped ECU, like the the one listed in the link I post earlier:  https://minkara.carview.co.jp/userid/444260/car/444612/2099320/parts.aspx He quoted 444PS with an unopened engine and twin GT2510s @ 1.1bar boost... sounds about right?
