How do I know if I pushing my two 12" kicker L5's two much
|
New member Username: Pervie_palPost Number: 6 Registered: May-07 | Hi I just got a concept cd-2410 amp to power my two 12" kicker L5's. Its the 3rd amp i've tried so far and I am stumped. The rms wat for that amp is 1200w rms @ 2ohms and my subs are rated at 600w each @ 2ohm. When I crank my volume past 25 the subs sound like they r getting to much power but dont know how this can be its either that or the back of my cab is makeing the noise. If u can help me with any trouble shoting or know wat the problem is plz call me 937-514-2925 or email me clifcll@aol.com my name is Neil thks |

You either have them at 1 ohm and getting too much power (if the amp doesn't go into protect), or at 4 ohms and you're probably clipping them since the amp only produces half the power you want at that impedance. |

New member Username: Pervie_palPost Number: 7 Registered: May-07 | The subs are duel 4ohm I have them wired down to 2ohms. The amp is a concept cd-2410 the owners guide says it puts out 300 x 1 @ 4ohm,1200 x 1 @ 2ohm and 2410w x 1 @ 1ohm. Its a mono block amp with two speaker outputs I have each sub wired for two ohms on each output. This is there site for specs on amp conceptcaraudiovideo.com |

Gold Member Username: Nd4spd18Southeast PA Post Number: 2901 Registered: Jul-06 | 2 DVC 4 ohm subs wired in parallel makes 1 ohm. So that amp produces more power than the subs can take. Set your gain based on how much power the subs can take, not the amp's 1 ohm output. |

Silver Member Username: BasssquaredKansas Post Number: 560 Registered: Nov-06 | M.S if he has each speaker at two ohms then it would create a one ohm load so that amp is giving those subs 2410 watts which is way too much for L5s or did i read something wrong here |

New member Username: Pervie_palPost Number: 8 Registered: May-07 | Wat do u mean by cliping them? The gain is set at just under half way and they sound good if I dont turn volume past 25. Uknow I think I know wat i did when I built box I wanted 1.75cft of airspace but i didnt figure in the space that the sub would take damm. B4 i built box I called Kicker the tec said that 1.75 in a sealed box would sound the best |

New member Username: Pervie_palPost Number: 9 Registered: May-07 | This amp is weard to me it a mono block amp with two chanels. I called concept the tec said if I run each sub @ 2ohm on each chanel it would split the 1200w @ 2omh like a two chanel amp but its a mono block amp. That is 600w rms on each sub but I cant turn gain past half way. If I have below 1.50 cft of airspace will these subs preform rite |

New member Username: Pervie_palPost Number: 10 Registered: May-07 | Is there a way to take a volt meater and find out the ohms? I like all types of music if I just build a different box but go with one of the kicker ported boxs insteed of a sealed one will it sound better or worse |

Gold Member Username: Nd4spd18Southeast PA Post Number: 2911 Registered: Jul-06 | Ok easy solution here: don't turn the volume up past 25. Or if you want to turn the volume up more, turn the sub amp's gain down. You amp has more power than the subs can take so you don't want it to be outputting full power. If you want to use that amp to it's full potential, get better subs. L5s are not very good. |

Gold Member Username: Nd4spd18Southeast PA Post Number: 2912 Registered: Jul-06 | " it will be louder but tipically sealed have way better sound quality " A low tuned ported box can sound as good as a sealed. Usually better due to the low end extension. |

Silver Member Username: BasssquaredKansas Post Number: 568 Registered: Nov-06 | then whats the point of the sealed if a ported box is louder and sounds just as nice then there would'nt be a point for sealed enclosures |

Missouri Post Number: 2513 Registered: Dec-06 | ahem, when he says low tuned he means tuned low enough that you can't hear the bad SQ effects of ports, right M.S? The point of a sealed enclosure would be when you don't have space for a ported box (larger) and still want reasonable SQ and need high power handling (hint hint). |

" Yes. I mean a box with a ~25-30 hz tune (of course it has to be designed correctly also). " The point of a sealed enclosure would be when you don't have space for a ported box (larger) and still want reasonable SQ and need high power handling (hint hint). " Exactly. Limited space applications is where sealed is useful in car audio. BTW, take a look at some high end SQ home audio systems if you ever have an opportunity. Most of those speakers are ported designs. |
