Time Alignment vs. Phase Shift

[audioholic 5,000+ posts]

If that was a problem, its not showing up on my scoresheets ... Modified class or Supermod Class.

You are obviously proud of your scores, and that's fine, but it does not change the facts. Any component added to the signal chain will add noise. Look up your EQ's specs, notice that is has a S/N ratio (if the published specs are thorough). This is a measurement of its noise level. While that spec may or may not be accurate, it is a testament to the fact the component generates its own level of noise.

In other words, with technology available to humans currently, it is impossible to make a component that modifies the signal chain without adding its own noise to the signal while doing it.

I still fail to understand why you have an EQ installed that you apparently have adjusted to seem as transparent and ineffective as possible. If you just wanted the xover functions, you had much better options to choose than an in-dash EQ.

This is why i'm here bro ... Awesome info, thanks.

My sub amp has a feedback circuit installed, that particular crossover is needed to function properly (Linear Power thing).

When I'm in a perking lot or at my sons football games, my truck need a little more "kick" than a SQ competion. I can change things on the fly when needed.

most people say i don't need rear speakers either, but I have a family that rides too. They could care less about staging and stuff, they just want daddys truck to be louder and sound better than anybody else in the parking lot ... lol ... With 2 teenagers, you can guess that these systems take alot of abuse !!!

The member touting the "minimal processing" spill even showed photos of your install as an example. Of course, I do find it ironic that he used photos of your install since the PA2 and XO3 are processors.The only thing I would pick on you for is using all those batteries for TWO amplifiers.//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif Long story short, I used to run Linear Power amplifiers, and I know for a fact that you need most of those batteries OR a set of jumper cables if you decide to listen to your system with the vehicle off.//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

I posted a photo of my old school Alpine HU here on CA.com and a few months later saw my photo being used on ebay to sell one.

It happens all the time I guess.

Thats identical to my PRA-H400 except it isnt Ai-Net.

I really like the black color better than the blue/gray mine has.

Any idea where to get the 4381 dealer wired remote control for those Dave?

I've considered finding the HU thats made to control mine (CDA-7949), but I've held onto my new 7941 for 12 years, and darn it I want to finally use it.

That and Im afraid that most 7949's are either worn out, or the people selling them in great shape want too much for one.
