Silver Member Username: Holt_champHtown, MI Post Number: 687 Registered: Oct-06 | what is slash series amp?? would i have the input on low or high voltage?? |

Silver Member Username: Holt_champHtown, MI Post Number: 688 Registered: Oct-06 | and a little off topic would i hear any differece if i used 1" opposed to 3/4" when i build my box? thanks everyone! |

Gold Member Username: Nd4spd18Southeast PA Post Number: 2277 Registered: Jul-06 | Slash series are JL's amplifiers. Your amp most likely won't have a high/low switch. We use that tutorial because it explains how to set the gain very well, just ignore the part where JL gives a table of voltages for their amps. Instead use that calculator I posted to find the voltage to use for your amp. |

Gold Member Username: OlegSanta Monica, CA USA Post Number: 1344 Registered: Nov-04 | Hey M.S., I've got a question for ya... I was setting my friend's gain today with my DMM. What should the sub out on the HU be set to when doing this? It's a subwoofer amp. Also, my DMM displayed a reading with 1 tens digit with 4 digits after the decimal point. Target voltage was 24.5V (600W into 1ohm) and I was able to adjust it for DMM to show 0.0024 and when the gain was all the way down, the reading was 0.0007. Do these numbers look right and why didn't it just show 24.5V when/if it got there? The measurement was set to AC voltage. Thanks! |

Gold Member Username: Nd4spd18Southeast PA Post Number: 2278 Registered: Jul-06 | What do you mean by "What should the sub out on the HU be set to"? If you mean the sub level, it should be all the way up. Everything else on the HU turned off or at 0. Is your meter auto-ranging? If not, you had it on the wrong range probably. If it is, something else is wrong...... |

Gold Member Username: Nd4spd18Southeast PA Post Number: 2279 Registered: Jul-06 | phillp: I'm no expert box builder, I probably not. Most people use 3/4 for their boxes. |
|
Gold Member Username: OlegSanta Monica, CA USA Post Number: 1346 Registered: Nov-04 | Yeah, I went the sub level. Ok, maybe that's what I did wrong - I set it to "negative infinity" lol Yes, my DMM is auto-ranging, but has manual override if I need it. I'll check again to make sure it's not in override mode. Thanks, M.S....life saver. |

Silver Member Username: Holt_champHtown, MI Post Number: 692 Registered: Oct-06 | yea i know they use 3/4 but i was wondering if 1" would be better for like flexing and stuff. im not sure but i will prolly end up usin 3/4" |

Gold Member Username: The_image_dynamicSan Diego Post Number: 1272 Registered: Dec-06 | If you can afford 1" go with it. I use 1 1/4" MDF for all of my boxes. |

Gold Member Username: Matt12490California USA Post Number: 2365 Registered: May-05 | What sub/s do you have philip? If they're powerful, you should use 1" if it is available. |
