Hey everyone,

Now that my system is going I thought I ask some questions on Head Unit tunning


I know the majority of users have Alpine (as do I) but I prosume other head units offer the same tunning ability in regards to aspecs such as bass, trebble, time allignment and so on.


Anywho, I was just wondering what settings you all have your HU's on?


At present I have no settings apart from the Subwoofer being set to 15 on my alpine deck (maximum power going to it from the HU), and the sub isn't really bassy until i set the bass up a bit, is this right?


Hope to hear some good responces !


Cheers,

Jason

'Bass' and 'treble' are nothing more then 2 channel Parametric EQ's with limited bandwidth. Treble usually focuses around 6-8kHz, with bass around 200Hz. Boosting these frequencies however, will cause early onset of clipping. So setting your bass to 15 (if 15 is the highest) will cause clipping extremely early. If you have an extra sub preout, these have their own gain too usually. Again, boosting will cause early clipping.

I tend to leave my headunit (and amps) as flat as I can, and tune using my PXA-H701. Its easier for me that way. To me, Quality is very important, and so clipping is very bad.

hehe thanks for the heads up

The set up on each car should be different I guess..Like TA, u need to measure the distance from where the speaker is to where u sit in the driver seat and so on (diff car, diff dimension). Have a read on the manual, I think most of the tuning are covered there

Yeah I understand with TA but i was thinking along the lines of settings like bass and tone etc


thematt for example said he keeps it all flat and tunes it with his ext proc etc

Ohhh yes, most of the SQ head here will tell u to keep the bass and treble from the HU flat (0). I set mine flat for both bass and treble, I'm using oldskul Clarion HU btw, fully analog, no TA, no EQ and other fancy stuff

So all the tuning in my system are from the mono amp for the sub level and freq, front 4ch amp for the midbass level and freq and the xover of the splits for the tweets level

Very nice

Yeah my system has been tuned by amps and HeadUnit left flat, so I was curious as to what other people had
