killer stereo tuning

[bastianshaw]

So after installing the $500 stereo some questions remain,
Im running this in 4 channel mode w the HPF's set to on on channels 1-4 and the LPF on channel 5

HPFs set to maybe the 3 o'clock position~120hz and gain or volume level set to noon or so

just wondering what settings you guys are running on ch 5 sub(i have the obcon)

i turned mine all the way up for sub "level" i need setting reccomendations for Bass EQ
Subsonic

preferably exspessed in the 123 oclock system as the gauges have no mid value

also im concerned about bowing my stock speaker is this valid at my current settings?

wow I thought someone wouldve posted

I am in the same boat, hopefully someone chimes in with more experience. I have been researching all day and am going out to turn some knobs now.

Went out and did some tuning, per the amp manual.

Really didn't get any distortion until I started to push the levels.

I could go higher on my sub level, but I like the sub just filling out the sound. I listen to rap and dubstep at times so turning just it up won't be bad. Plus it is just a small 10" sealed box for now.

This amp is great, Luke was spot on about this amp. It is super clean. I didn't realize how loud it was until I went to talk to someone.

I could probably push the settings a bit more, but my speakers only handle 60W RMS, This amp pushes 70W RMS at 4 OHMs. I didn't want to get too crazy and test Jensen's ratings:p

!!!!!!!THESE SETTINGS ARE NOT ON STOCK SPEAKERS!!!!!!

I am running Boston Acoustic Rally Series.

What kind of speakers are you running??

Coaxial? Passive x-over with mids and tweets?

If coaxial then you should still run full range as the capacitor will keep the lows away from the tweeter portion. If you are running passive crossovers then the same applies. If you are running tweets and mids separate you want a three way type setup. Full range to the mids and tune from there, high pass to the tweets. Right now it looks like you have tweets and a sub.

No, this is incorrect.

the High Pass filter is to protect the bottom end of the midrange, thus is it in the 80Hz to 120hz range, not 5khz or so as it would be were it for the tweeters..

Unless you want your mids to flop and fart like Blunts latest lovers' rectum after a rough night of butt-lovin, I recommend you turn the high pass to somewhere in that 100Hz range.

Dunno if this is at the OP or me.

But I am running boston acoustic rally seriers up front, with a tweeter and x-over.

The rears are a boston acoustic 2-way RX67 is the model number on those.

I dunno if I wanted to run the HPF on the rear too just to keep them out of the real bassy stuff. They seem to still catch input for some low notes that make them sound like crap when I had it on full. I think they need replaced anyhow.

It sounds great though. Especially the fronts.

Lol exactly what I noticed when I left it on full without the HPF.

So then does it only work this way when the head unit is set to three way? I have mine set on three way with the rear channel for the sub amp, the front for the tweeters and the middle for the mids.

I have the mids on full range, but the three way setting of the crossover restricts the signal to the middle frequencies.

I think I answered my own questions and realize why my previous post was incorrect. My apologies.

Ah HA! You haz the highest end of decks, so you can piss off!

No, seriously, you figured it out. Switch your deck back to 2 way, you will get high pass filters in the range shown.

luke can I suggest you add the jenson settings to the killer guide w oclock values for all the settings?

OMG: Sig worthy ... "Unless you want your mids to flop and fart like Blunts latest lovers' rectum after a rough night of butt-lovin, I recommend you turn the high pass to somewhere in that 100Hz range."

can someone explain to me the settings for channel 5? shown in post #4 above

[bastianshaw]

Anyone know off hand what frequency the lukebox is tuned to?
trying to set my subsonic and everything ive read recommends setting it just below wht the box is tuned to guess ill just leave bass EQ set to 0?

The far left knob is the gain knob. This just adjusts the power going to your sub. I tuned this so that the level of sub output fit with the rest of the system evenly (not just all bass) and so that the sub was not distorting at high levels.

The subsonic knob is there to help protect your sub. It rolls off any frequencies under what you have it set at. This protects your sub from playing to low of a frequency and hurting itself. This is pretty helpful with ported boxes if I understood correctly. Should be set somewhere around 30 hz I believe.

The next knob is a "boost" type knob. It gives the bass more power without necessarily causing more distortion, which you would get by pushing your gain up. More of this boost is safer on sealed enclosures, don't go nuts if you are using a ported box. (mine is sealed for now)

And the last know on the right. That knob is a highpass filter. It's main job is to stop your sub from trying to play to high of a frequency and causing itself damage and just sounding like crap. You want it set between where you think 80-100 Hz is.


Keep in mind the settings you are seeing there are not on stock speakers. Also remember that these knobs are pots. This means that they will not all be the same from unit to unit. So to find your best sound you may have to do minor adjustments one way or the other. To do that though you need to understand what each knob does, so that you know what to listen for and tune out.

Hopefully I explained that right.

I thought I remember reading somewhere Lukes box was tuned to 33Hz.

With a ported box you should be able to use the Bass EQ or "boost" to about the middle. You could always tune it a little bit higher, but I wouldn't do so for everyday, to prevent damage to your sub.
