EQ215ix

xclusive · Post by **xclusive** » Thu Oct 15, 2009 3:56 am

I am running a set of components in the front, 6x9's in rear for rear fill and a pair of 10's. I have a 4 channel amp controlling the highs and a seprate amp controllng my lows. I just installed EQX215ix and when installing the front and rear channels from my HU goes into a left & right channel. Since this is the case will I not have the ability from the HU to control fades right to left and front to rear. Any help would be greatly appreciated...

Thanks,

Left right should function as designed.

You will only lose F/R fader if you want to EQ all four channels with a single 215ix as it only has stereo inputs/outputs. You would have to combine four channels into two to feed the 215ix. No advantage doing that.

Split your HU signal BEFORE the 215ix and only EQ your front stage and drive the rear fill directly from the HU. The HU fader will continue to function with this setup.

Or insert another 215ix in the rear signal path.

You can still fade left and right, but no longer front to rear.

I didn't mention that I do have a bass cube as well. What would be the best way to hook up this setup to give me the most flexibility. I do have a sub amp rca off my radio as well. Should I use those and with the sub bypass the exq and go directly into the basscube?

As far as using the bass cube goes.... rca from eq to the cube, rca's from cube to the sub amp. You may want to acquire an lpl to plug into the EQ for overall sub volume as well as using the bass cube volume knob for the one freq, (you would then have 2 separate controls)

, You have as your set point/sweet spot. This is the same to my set-up. I do have 2-215iX's but for what you are doing it doesn't factor in so much. You may want to run your 6x9's using the bandpass RCA out's from the Eq.

Where would I be able to purchase an lpl?

Thanks,

I have seen them on Ebay for less the 35 bucks.

Fading is for front/rear, balance is left/right.

Wrong nomenclature I guess. Despite being worded incorrectly, I believe my thinking is correct.

The way I would do it. You will lose the front to rear fade but unless you want to add a 2nd EQ215 this is what you need to do.

Use the Xover in the head unit and by pass the one on the 215ix.

sorry to sound dumb but is the lpl & the lpl44 the same thing?

Thanks,

Not dumb at all .... LPL and LPL44 are the same

Hmmm... I disagree with your point about "no need for LPL" because he has a basscube. They have completely different results.

A basscube works by boosting a small frequency range. This is exactly like the bass boost on the amp, but with the basscube you can adjust the frequency (on the amp it is only 45Hz), and the Q (frequency range affected). Narrow Q means you affect only a small range of frequencies, and wide Q means you affect more. It doesn't boost all frequencies evenly however... it has a bell curve shape to it.

By contrast, the LPL works like a gain knob. No signal is artificially boosted, you only increase the sensitivity of the amp by turning it up. This means the volume of all bass is affected.

The LPL is perfect for tracks that have a very quiet bassline, and you want a bit more oomph. The basscube is better for ported setups, where you can set it to the port frequency and get a ton more output at that frequency (though your system ends up sounding like a one-note wonder).

OK, I was wating the LPL basically to be able to turn the bass up and down (not change frequencies) easily from dash. This will work for this, right? or do I have the concept wrong

They both turn your bass up and down, but the LPL changes the volume of your whole amplifier (so all bass frequencies are affected), while the BassCube affects a narrower frequency range.

YES^ LPL attenuates the whole low pass spectrum, while a bass cube enhances your selected frequency.

i would run both if budget allows.

With the head unit having a sub out. Why would you need a lpl? You can control that from the deck .... Unless you want that much more control .... I guess it depends on the HU some are not that easy to change the sub out level. I haven't ever felt the need for a bass cube or lpl in my systems....... But I do own both for some reson

don't remember were I got them.

If you want yo use the Lpl . Put the BC on the low pass out put of the 215 and not the sub out of your head unit.. You will end up only using the front left and right output of the headunit at that point . That sound about right Tom???

I find it more annoying to get into the menu than to turn a knob. Also I have found with Ryan's old Alpine at least, that the sub out channels cause clipping when you turn up the volume beyond 5 or so. Leaving that at 0 and using the LPL seemed to work the best.

Yes you would want to use the BC on the low-pass output of the headunit.
