Can you talk about soundsystems here?

hey guys, noob here, just bought an Alpine cva-1005 aesthetic rice stereo. Do most aftermarket stereos use the same wire harness jack? The PO of my mr2 wired up the stock harness for a jvc unit, however the jack itself that plugged into the back of the jvc fits perfectly into the back of my new stereo. I haven't tried it out yet because I'm nervous about whether or not the pin out is the same or not. Is the pinout a standardized thing on stereos?

I think he was trying for irony.

There are a few standard connectors, so if it fits it should work fine.

>Do most aftermarket stereos use the same wire harness jack

Yes ISO 10487

Heres the jack. I don't think its 10487. Does this have a name?

Do why does the SMPS in my head unit have 22V rails?

Don't bother, you wouldn't have a clue.

Just put an aftermarket fiberglass trunk on my car, and now my sub makes it rattle like fucking crazy. Will Dynamat help out with this at all?

A bit, however the shape of your trunk and size can make a big difference

What head unit?

Little cheapo Alpine CDE-142E. The Toyota OEM unit it replaced could also get 20V at the terminals with pink noise into a 40w ceramic resistor and with no load. Output stage can't output more than rail voltage, and rail voltage is presented to the load when the output stage is clippes, so what do you think that means?

Why do you keep talking so much utter dribble that blind freddy could disprove if he was stuck on Google in 2004? And stop calling a power supply a DC-DC converter. A) that would be a buck/boost converter you basic fuck and B) there happens to be a wee bit of filter, choke and smoothing to be done, not just upping rail voltage with a buck/boost. That might be why even a Nakamachi head unit from two decades ago has a little regulated power supply in there, and not what you mistakenly believe to be straight B+ to the output stage.

Although those little silly Drok things are exactly that.
