Guys,

Wanting some info please so i can input a good set of parameters for my car. Firstly I'm not clue'd up on audio other than knowing Bass is 'duff duff' etc.

The sound stage at the moment (I know its not ideal), is:

JVC headunit (this is a half decent HU was about £100)
Rear 5" speakers in behind the seats with tweeters.
Front Alpine door speakers with tweeters (were around £100)
Ripspeed under seat sub 100w peak and 50w RMS - connected via phono leads to the HU.

Now the Headunit has settings for Bass/Treble/Mid/Fader and the phono connection can be set as 'sub' or 'rear' its currently set as 'Sub' which enables you to set the Freq (60,80,100,200) unlike 'rear'. The bass/treble/mid settings available are:

Freq (Hz) 60,80, 100, 200
Level 1,2,3,4,5
And Q1.2, 1.25 etc - what ever the hell that is?

And the sub which I'm more puzzled by:

L.P.F (loss pass filter?): On/off
Freq: Turn knob 80-200Hz
Phase: Normal/Reverse
Remote: Level of the sub.

Its probably not set up right as i dont understand the settings but considering the make/spec of the sub I'm pretty happy TBH.

Hoping someone could explain the settings and what sort of settings i should go for and how they should match to improve sound quality? - My preference is a bit of bass.

I know its personal preference, but I think I wont have it setup to its full potential/or wrongly.

Thanks

LPF is low pass filter. If you are sending a signal which is not a dedicated sub channel turn this on and set to 85-90Hz.

Phase:- Normal

Remote:- Normally the level at which the sub will turn on from a audio signal.

Connect the Sub to the sub connection and set the frequency to 80Hz. The level and Q values are probably the strength of the signal, make sure the amp is not clipping or the speaker distorting. Read the manual on that one.

Q value is the 'width' of the frequency band you're editing with the equalizer I think. So a large Q value will mean each frequency band is large, so they should blur into eachother and create a smooth transition. If you want to try and adjust specific frequencies without affecting the frequencies either side quite as much, choose a low q value.

chrispayze

I hope the above makes sense if not, imagine you're adjusting the 80Hz band. A low q value might mean it adjusts frequencies from 75-85Hz, whilst a high Q value will mean that the same adjustment might change the levels from 70-90Hz.

Otherwise known as selectivity

An amplifier with a high Q factor will have a low gain, and an amp with a low Q factor will have a high gain.

They both have benefits (of which I shall not bore you with the details), which is why some systems, such as a Super-Heterodyne receiver, uses a multistage amplifier to ensure a wide frequency range can be received and a good SNR is maintained by rejecting image and adjacent channels.

Thanks chaps, i will give these a try tomorrow.
