When i set my amp to 4.0V gain, it barely moves the W7, but when i set it to 1.0V it starts to really make a nice difference. why does the alpine instruction manual tell me to match the gain to my preout Voltage on my HU? It sounds way louder and better at 1.0V |

Bronze Member Username: MrsqCalifornia Post Number: 76 Registered: May-06 | but your 600walpine is not enough to push the 10w7 plus its probably even peak not rms please verify it |

Bronze Member Username: Brycew7B.C., B.C. Post Number: 56 Registered: May-06 | The alpine is 400 W RMS at 4 ohm, 600 W RMS at 2 ohm. |

Bronze Member Username: MrsqCalifornia Post Number: 80 Registered: May-06 | ok bryce, but hope your using 600w at 2ohm so you can atleast power the w7 adequately |

Silver Member Username: HomegrowncamWatauga, TX United States Post Number: 287 Registered: Jan-05 | can you run that amp at 3ohms? |
|
Silver Member Username: LexuscoopPheonix, Arizona USA Post Number: 864 Registered: May-06 | if its 4 and 2 ohm stbale you can, it will be gettin like 500RMS or so |

Gold Member Username: Alias747MN Post Number: 1075 Registered: Apr-05 | Any amp that is 2 ohm stable will run @ 3 ohms. Like Shaine said, you just won't get as much power as you would at 2 ohms. You should have a decent match there. |

Silver Member Username: LexuscoopPheonix, Arizona USA Post Number: 874 Registered: May-06 | no, he'll be under powering it by about 250RMS, if i remember correctly the RMS of the w7 is 750 and he'll be gettin around 500RMS... it wont sound horrible or anything just underpowered, you might blow it sending a clipped signal though... |

Gold Member Username: Alias747MN Post Number: 1076 Registered: Apr-05 | No the 10w7 is 500 wrms. The 12 and 13.5 are 750 and 1000 wrms, respectively. |

Bronze Member Username: LicidBrunswick, Ohio USA Post Number: 75 Registered: Dec-05 | ^^^correct. That amp is fine for that 10w7. should be giving it around the right rms, maybe a lil under maybe a lil over. either way that amp is fine for the sub. |
|
Bronze Member Username: Brycew7B.C., B.C. Post Number: 58 Registered: May-06 | yea , it's a SVC 3 Ohm , the amp is decent, it's just not pushing it like i see the W7's in www.realmofexcursion.com video's where the W7 looks like a donut on steroids doing bicep curls. |
