Ohmage vs sound quality (regarding FI Q/PPI3000/1 combo)
|
New member Username: Style_frontPost Number: 1 Registered: Oct-06 | I am online right now about to pick up a FI Q15 and I am trying to decide between the 1ohm dvc and the 2ohm dvc speaker. Ive read that the 1 ohm load has more distortion but 2 ohms has double resistance, or half the power. What's the real story hear, wich is better, looking for SQ system. Thanks guys. |

New member Username: Style_frontPost Number: 2 Registered: Oct-06 | Just trying to figure out wich ohm load to wire my subs for the best signal. The ppi d3000/1 has plenty of power for this sub in either configuration (1000rms @ 2 ohms, or 1475rms @ 1 ohm), so in one hand there is a little better sound?...in a 2 ohm setup..... and in the other hand I can have 3000watts on tap, but I don't know if the FI Q can handle that much. What would you guys do? |

Gold Member Username: JuliobSanto DomingoDominican Re... Post Number: 2672 Registered: Dec-05 | another question, what's the price on the PPI cuz their quality is not the same, and maybe you can get a better amp for the money, but if you can get it cheap, go for it |

New member Username: Style_frontPost Number: 3 Registered: Oct-06 | "another question, what's the price on the PPI cuz their quality is not the same, and maybe you can get a better amp for the money, but if you can get it cheap, go for it" Ive never read any problem with the quality of PPI amps, and ive also heard one 500watt PPI amp powering 2 12 inch L7's pretty nicely.....the only complaint is they run hot. Lemme find the link, ive seen it on ebay for 444, but ikesound has it for 420 http://www.ikesound.com/product-product_id/5247 What is an alternative to the PPI? |

Post Number: 2678 Registered: Dec-05 | They're not bad, i've never said that, but saying that their quality is not the same, you might not get the product you have in mind... For that amount of money i'd get a better amp... ED nine 1, 315$ would be a good choice, good quality, cheaper and almost the same output with 100$ less |

New member Username: Style_frontPost Number: 4 Registered: Oct-06 | The output is not even similar, PPI is rated for 2000 max at 2 ohms and 3000 max at 1 ohm. I looked around online for a few minutes now and I can't find any max ratings for ED nine.1 Another amp I like is crossfire but the bigger ones are expensive. |

Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3752 Registered: Oct-05 | lol. another noob.. MAX rating have no such purpose whe looking at the amp specs, the amp will NEVER EVER put out a MAX power rating. thats the power that an amp can put out until the amp blows up basically. i woiuld get the ED for 315 and a full 3-year warrenty i belive also |

New member Username: Style_frontPost Number: 5 Registered: Oct-06 | How irritating, but thanks for your opinion. Thats what I'm trying to do hear what you guys think, or would do. I know the max is not important, rms is the indicator of an amps power capability. The only reason I ask about max power is I thought that some amps were regulated, for example the JL 1000/1, it runs 1000 watts RMS @ 1.5-4 ohms, but thats all it will do, no surging up to 1500 momentarily because of the circutry (or some ish like that.....). |

New member Username: Style_frontPost Number: 6 Registered: Oct-06 | Perhaps I am wrong about the power being regulated though...... |

Silver Member Username: JohnfiacIL USA Post Number: 509 Registered: Mar-06 | I havnt noticed really a difference in ohms unless i got from like 1-2 to about 4ohms.. |
|
New member Username: Style_frontPost Number: 7 Registered: Oct-06 | I just read about a phoenix gold 1200 watt amp wich operates in the same way the JL amp does, full RMS at 1-4 ohms. Can any one confirm or deny this since PG doesn't mention this on there website for me? This sounds really interesting @ 400 dollars.... |
