I just put this into my 2000 dodge intrepid and need to know where to start as far as tuning it. Heres what I have:
Sony CDXMP70 head unit
2 JL AUDIO 12W3V2 D2's (setup to 2 ohm load so each recieves around 400w)
MB QUART RCE269 6X9 2 way component
ADS 346CS Components
Alpine MRV-F545 125w x 4 @ 4 ohm
Alpine MRD-M1005 1000w x 2 @ 2 ohm
I know that user preference plays a big role, but I'm just looking for some starting points.
http://dodgeintrepid.net/photopost/...861box8-med.jpg http://dodgeintrepid.net/photopost/...861box9-med.jpgHere is what I need help on:
1.) Sony CDXMP70 head unit has LP crossover at 78hz or 125hz and HP crossover at 78hz and 125hz. What should I set them too or should I just turn them off?
2.) Settings on the MRV-F545?
Channel 1 and 2 are the fronts, CH3 and CH4 are the 6x9's
CH1,2 filter: HP, LP or OFF?
CH 3,4 filter: HP, LP or OFF?
I would think HP for both is the correct choice?
When the frequency multiplication switch is set to the
“X1” position, the crossover frequency can be adjusted in
the range of 30 to 400Hz.
When the frequency multiplication switch is set to the
“X20” position, the crossover frequency can be adjusted
in the range of 600 Hz to 8 kHz.
Which position should I set it for CH1 and CH2? What frequency should I set?
Which position should I set it for CH3 and CH4? What frequency should I set?
Input channel: Set this switch to “3/4” to have the inputs of
CH-3/4 accept independent input signals. An
example of this application would be the use
of a head unit with dual pre-amp outputs. Since I have dual pre-amp outputs, this selection of 3/4 is obvious.
Gains: I can choose between 0.2V – 4V. I'm thinking that 1V is about 75% of the gain turned up? My speakers can handle 60 - 150 RMS, so 100RMS to each should be good, right?
Bass Eq: Adjustment range: 0 dB – +16 dB What should I select? For CH1/CH2 and CH3/CH4?
Settings for the MRD-M1005:
Crossover Frequency: My range is 30 to 200hz. Is 80hz good for the subs?
Lowpass Filter Slope Selector Switch
The Lowpass Filter slope can be set for either
12dB/oct. or 24dB/ Not sure what to do here.
Subsonic Mode Selector Switch: 0, 15 and 30hz
I take it that I set this switch to “OFF” when I want to hear tones not possible when the Subsonic filter switch is used.
Gains: Adjustment range 0.1V – 8V: I'm thinking that 2V would be round 75% of the gains turned up. Should this be what I set it for to get around 400w to each sub?
Bass EQ adjustment: Adjustment range: 0 dB – +16 dB: What should I put this at?
ADS crossover settings:
Tweeter phase: 0 or 180?
Tweeter Level Switch: 0 -3 +3 db?
Any help on this so that I can avoid paying alot to have it tuned professionally would help. i'd really like to learn to be able to do it, but there are just so many combinations and trial and error is hard.
