So my headunit has Time alignment and I was thinking about messing around with it as I never have before. Can anyone point me in the right direction.
Some DSPs have a microphone and can auto-time-correct if set to. Like this:Measuring tape, put in the numbers. Use mono pink noise to adjust manually to correct if needed
I believe what Los was referring to is the overall autotune capability and known excellent results from JBL MS-8 in a wide variety of configurations and vehicles. It is a flawed DSP, but it was way ahead of its time.I'm sure, but mono time correction may be almost as good as stereo.

Well I bought and just received an Alpine PXA-H800 DSP so I will let you know how it works! May have to buy a cheap Windows tablet or something with a USB port on it cause the PXA-H800 has a USB port like a printer, and comes with a printer USB to STD USB cable to connect to a Windows thing.I believe what Los was referring to is the overall autotune capability and known excellent results from JBL MS-8 in a wide variety of configurations and vehicles.

Time correction/alignment is essentially based on distance, which doesn't require two microphones to set quickly and accurately. Two microphones and some brilliant hardware and software, on the other hand, can make a vehicle sound good in a very short amount of time. I know this from experience with MS-8. I have not used PXA-H800.
Unfortunately the alpine processor is not a simple plug and play, it requires 8+ hours of initial tuning andeven over a year of tuning, it will still sound better day by day. That being said, do not rely on the autotune, its not very good. You need to go manual and set crossover points properly along with manual time alignment and EQ. I can walk you through it if needed.I'm sure, but mono time correction may be almost as good as stereo.

I'm pretty familiar with EQ adjustment, it's just a question of getting into the controls for it. Yes, I'd appreciate any and all help with tuning this system once we (my installer guy and I) get it all put together. I figure I'll use the auto-tune then fine tweak it from there. One step at a time.Unfortunately the alpine processor is not a simple plug and play, it requires 8+ hours of initial tuning andeven over a year of tuning, it will still sound better day by day.

Thing about autotune is that it will either lower or boost frequencies depending on what it deems missing. Usually get really bad bass boosts when you let units autotune and introduce a lot of distortion to the amps at higher volume levels
Does you guy know what a RTA is and how to use it?I'm pretty familiar with EQ adjustment, it's just a question of getting into the controls for it.

I was wondering how mandatory it is ? can we expect good results without it ?Does you guy know what a RTA is and how to use it?It's a must have for tuning
