Help with Sys Config - 4 spkrs, 1 sub, 2 amps
I am planning an audio upgrade and need some help on the best way to
wire it. I have: Rockford Fosgate P325.2 Amp Rockford Fosgate P450.4 Amp Pioneer DEH590IB Head Unit (3 X 4V preouts - front / rear / sub) 10in infiniti kappa perfect sub (4 ohm) pioneer front / rear (4 ohm) Stinger SWCKH44 multi amp wiring kit. (comes with 2 RCA interconnects) Assume: 1. Bridging sub on 2 channel amp 2. powering 4 speakers from 4 channel amp. Is it better to: 1. Connect the front / rear RCA outs from the head unit to the 4 channel amp and then LPF pass thru to the 2 channel amp for the sub? (running 2 rca's) 2. Run 3 RCA's from the head unit (f/r/s). 2 (front and rear) to the 4 channel amp, and 1 (sub) to the 2 channel amp? (would need an extra RCA cable....money isn't a concern if better sounding) |

Help with Sys Config - 4 spkrs, 1 sub, 2 amps
I'm new here but this is simple enough, thought I'd throw my 2 cents in and try to help. I hope I don't offend any of the resident Car Audio Scholars with my meddling. First off, buy the extra cable for the sub and run it. Since the head unit features pre-outs for all 6 channels, take advantage of this, you paid extra money for this feature. The neat thing about this feature is that it gives you control of all the channels right from the head unit. If your head unit has built in crossovers that are easy to define and use, you should use them as well. This combination of features makes it so much more convenient to dial in a good sound right from the drivers seat. Don't, I repeat DO NOT skimp on cables. For best results with minimal signal loss and no interference, make sure all of your RCA cables are of the highest quality. The 12 dollar Radio Shack jobs are not really up to snuff. Assuming that your head unit has built in crossovers and a separate subwoofer level control, set your amps to full range (if they allow you to do so) use your head unit to dial in the sound. Be sure to run amp power leads through one side of your car, RCA cables through the other, this to help insure you won't be getting any electrical interference from the cars charging system regardless of how expensive your RCA cables are. Don't skimp on amp power wires either, you want to keep your amps fed with plenty of current through the thickest wires they will accept. It is a good idea to run at least a 4 gage all the way from the battery to the amps and use a distribution block to step it down to 8 gage (thinner wire) as close to the amps as possible, this to ensure max current flow (I'm assuming the amps will not accept thicker than 8 gage) Keep your ground wire as short as possible. Follow the first example with this, using 4 gage all the way to the amps, then using a distribution block to step down to 8 gage right at the amps. When grounding, it is important to have a freshly exposed shiny metal surface to ground to. rTo do this, you may have to remove any paint down to the bare metal, remove also any dirt, oil or contaminants in this area. Sandpaper to remove paint and contaminants, followed by rubbing alcohol. Oil or grease should be removed with a solvent first, wiped dry with a clean rag then sanded, then wiped clean with alcohol and a clean rag. To maintain a good contact surface, treat the freshly exposed metal surface with a silicon that is used for electrical contacts. The idea is getting a freshly exposed metal surface for grounding, and keeping it that way by preventing corrosion. (make sure the battery terminals are treated the same way, remove them from the battery, using a battery terminal cleaner/brush, brush, clean and spray them as well) This helps to insure max current to your amps. 1 other thing, if you're bridging the sub amp, make sure it's not getting any less than a 4 ohm load. I'm assuming you already know all of this, just thought I'd throw it out there. If you find any of this info to be useful and are looking for some tips on tuning, post a reply, I'll be more than happy to help. Sorry if I stepped on anyones toes, I know there are some forums that are dominated by territorial tutors that take offense when anyone new tries to answer questions.. Hope it helps. Good luck. -- lust4sound ------------------------------------------------------------------------ lust4sound's Profile: 55269 View this thread: http://www.caraudioforum.com/vbb3/sh...d.php?t=285937 CarAudioForum.com - Usenet Gateway w/over TWO million posts online! -- Posted via a free Usenet account from http://www.teranews.com |

I'd run 3 sets of RCA's, then you'll be able to use your fader and sub
level settings on your HU. |

That configuration is also what I thought would be best. Although, I
have a fairly credible source that hands down says it is better to go with option[1]. I know the HU does have fairly good control over the outputs. I am pretty sure I am going to go with option[2], unless anyone else has a good argument..... |

You seem to have your sh*t together, I'm sure it will work out just fine. I'm not a seasoned Veteran, as a matter of fact, I'm more qualified to learn than I am to give advice, but this topic is like Car Audio 101. 1 of the basic rule of thumb things you learn, so I figured I'd throw it out there.

Also i ran it right next to my 4 ga. power wire all the way up to the amp so im not saying its not true just saying that i have done it before and never had a problem with it. |

SWCKH44. It isn't on stingers website but is found randomly on the internet. I paid 212 incl shipping on ebay, and expect to pay 30 max in canadian border tariffs. It retails for 335 + tax in canada @ futureshop. The neat thing about the kit is that two of the components have LED screens on them (distributor block current [ithink] and cap voltage). Also, it comes with crimpers... I actually haven't seen the kit yet [out of box], I am on a work term and shipped everything home. I am patiently waiting for 2.5 more weeks.... |

Caps will reduce alt whine but do nothing for ground loops [oh how it isn't as easy as assuming all metal is the same point!] Cheers Not wanting to be a buzzkill, but this doesn't make any sense. The load on the power line (and therefore external cap if installed) is not going to track the input or output signal in anything but a very general sense of average power. The power lead to the amplifier goes to an internal cap, which feeds the switching supply that creates the +/- DC voltage rails. The presence or absence of a stiffening cap is not really relevant to inducing noise on the input or output signal lines. As far as phase angles from input to output, it depends on the amplifier design and how the output stage is wired to the speakers. It's really irrelevant with shielded cables, but as long as the speakers are wired correctly with regard to each others phase, the phase angles of the signal wires can be ignored. Without a delay line or signal processor they will either be in phase or 180 out of phase. As a practical matter, the RCA cables should be of a quality, shielded design. Most are gold plated but this is primarily for aesthetics (and corrosion resistance). They do not have to be brand names, and you could make plenty nice ones from Radio Shack parts if you were so inclined. Regarding alternator/ignition whine, grounding problems are easily the number one source of noise. This must usually be corrected at the head unit, as that's where it's most commonly introduced. The stock wiring harness is usually ok for everything but the ground. Chris |

Ground loops and alternator whine also contribute. Caps will reduce alt whine but do nothing for ground loops [oh how it isn't as easy as assuming all metal is the same point!] Cheers- Hide quoted text - - Show quoted text - no i have never run a cap in any of my systems. Usually my alternator has been big enough to support the loads that are being drawn (although i have never really been a huge fan of super big sound systems, just somethin that hits nice and tight) But, not saying that a cap is useless, i have found them to kind of be overmarketed, if you have a problem with dimming lights just upgrade your alternator. Its more expensive sure, but then you dont have to worry bout it anymore. |
