What type of X-Over on PPI Amp to use?
Hi. I didn't get a reply to my last post and so I am hoping this subject
will help me get an answer. I have a modern Pioneer Head Unit that feeds the front speakers (door and dash/tweeters), back speakers and the RCA out goes to a PPI 2120 amp and then to a JL Audio 10" sub. Hence only the sub is amplified. What I need to know, is to what X-Over Freq 20Hz-5kHz should I set it since it is only feeding a sub. And also, for the X-Over type, should I choose FULL/HPF/LPF ? I just want to understand how X-Over are supposed to be set. Thanks. |

What type of X-Over on PPI Amp to use?
You'll probably have the choice of two X-overs. A X-over is just a
filter -- it can be as simple as that. Filters typically have two or three key characteristics: (1) Cutoff Frequency - point where the filter actually has a measurable (3dB) effect. (2) Slope - how aggressive is this filter, 24db/octave would filter 'more' than a 6db/octave slope would. (3) Filter type... For our discussion we can ignore this, but filters can have different 'shapes'. A subwoofer is that: It is a woofer that plays 'sub-frequencies' which are lower than that of normal human speech. This being the case, it is built do just that: It is large and relatively heavy when compared to other speakers. It must induce a lot of low-frequency (slow changing) changes in air pressure. To allow it to the best job, we should only feed it with lower frequencies -- Hence use the LPF (low-pass filter) for the sub. Your (1) Cutoff frequency will be up to you ears, and characteristics of your sub and its enclosure. Typically it can range anywhere from 60 - 120Hz. The (2) slope will depend on which filter you choose to use. You will probably have one filter available at your headunit, and probably another at your amplifier. I would use one, and turn the other off. If you were to use both though... the slope would sum (ie a 18db/Oct inline with a 12db/oct filter would result in 30db/octave filter... for the most part). The (3) filter type will be defined by the HU/amplifier. You have no control of it. Hope that helps. Gordon "[80s.fan]" wrote in message . .. Hi.

Oh, I'm sorry...I have never ever installed PPI [nerd]. I would suggest that, because the title of the post is "What X-Over to use with a PPI amp?" If you are going to drop the money on a PPI amp, at least use a decent crossover. Yes it has a built in crossover, however you do have near the control of your crossover points like you do with the audio control or any electronic crossover for that matter. Tell me what is easier to read: ::THIS:: OR this Now if I were to ask you to place a dot between the "H" and the "I" which would you rather work with? -- SFarris ------------------------------------------------------------------------ Posted via RealCarAudio.com - The checkmate of the caraudio community. http://www.RealCarAudio.com SFarris's Profile: http://www.realcaraudio.com/forums/m...fo&userid=2572 View this thread: http://www.realcaraudio.com/forums/s...threadid=13182 |

The PPI PCX crossovers are detented and the manual has a page that will tell
you exactly what your crossover point is at each detent. I'll take that over any type of non-detented "guessing game" crossover (like an AC) any day. Paul Vina "SFarris" wrote in message ...

please... why would you hose up the signal path like that? Using the
built-in crossover on any of the PPi amps built in the last few years is a far better solution than tacking a frigging AC module ahead of the amp.

What type of X-Over on PPI Amp to use?
you will want to set you crossover to LPF mode. Its called low pass and
will allow only bass to pass through to the woofer. For subwoofer base you should set the roll of frequency to somewhere between 50-125 hz depending on what sounds better for your car.

What type of X-Over on PPI Amp to use?
I have a PPI PC-2100. I do have to agree with the other guy, I was not too happy with the built-in crossover. I did add an audio control 3xs module type crossover and found that it sounded better with it. I was also getting a minor input hum from the front (mid/high) channels of the amp that the audio control 3xs totally cleared up. Funny thing is that the noise was only there with the PPI amp, I have also tried an Alpine and an MTX amp for the mid/highs no noise was present.

What type of X-Over on PPI Amp to use?
And, I am very skeptical about the built-in crossover causing noise that
was fixed by adding another component in the signal path. That's just not particularly plausible... you have to remember nothing in the front end changes when you turn off the crossover except whether you routed through a crossover or not. What's more likely is that there was some kind of screwed up signal ground path that actually agreed with A/C's funky grounding philosophy. PC and PCX amps are some of the best amps around at rejecting noise on the input cables, you have to go out of your way to make them pick up noise. Probably had the inputs cranked to max sensitivity, and had to turn them down to use the ouboard crossover... I'm sticking with the advice (in this case) to use the built-in crossover.

closest, they all slam. JD specially that one CA&E just labeled the "new SPL champion" John from MMXpress.com wrote: Thanks! Nice to be back. Doesn't look like much has changed, other than some names, and all new spammers. :-) BTW, which sub hits the hardest? |

not at all... no more than you would "have" to swap motors if someone
offered you a new one for the same price you paid for the old, but that had twice the torque and twice the horsepower. JD John from MMXpress.com wrote: Nice... Does that mean I have to upgrade my HCCA to an H2? Anyone wanna buy an Orion HCCA12? Only slightly abused. :-) |
