New member Username: BwsheetsPost Number: 1 Registered: Jul-07 | I currently have 2 alpine type r 12 inch subs. I'm pretty sure they're the 4 ohm model. I have them hooked up to a jl audio 1000/1 amp. I believe this is too much power for them and I'm not too happy with the sound. So I am going to buy a new amp. I was considering buying either 2 alpine m650's or 2 mtx 4501. That way I have 1 amp for each sub. The reason I am considering the mtx amps is because I might sell the alpines and get two mtx 8500's instead. I don't know what to do. What do you think? |

Bronze Member Username: Chuck78Post Number: 67 Registered: Mar-07 | ok... 1. how are the subs hooked up? all series, all parallel, mix of the two? 2. how do you have your gain set? 3. what kind of box do you have them in? |

Are you Dumb or what??? you should be more than happy with a jl 100/1 pushing those subs. Maybe you have wrong settings or you don't like the way your subs sound cuz there's no logical explanation to your statement. IMO don't change that amp and check your settings. |

New member Username: BwsheetsPost Number: 4 Registered: Jul-07 | 1. The subs are wired at 2 ohm if that answer's your question 2. the gain is turned almost all the way down 3. they are in a good quality slot ported box. Juliob.. malik... fk u both, i came here with questions i was not looking for criticism. My amp keeps overheating. I've had 2 jl 1000/1 and 1 13w7, all of which have screwed up in different ways. For the prices that jl charges their products should be more reliable, everything jl i have had has given me nothing but trouble and i don't want anything jl anymore. I've had 3 sets of mtx's and I have loved them all. So, i was thinking about getting 2 mtx 4501 (one amp for each sub because I've seen other multi-amp applications that have been great) If i like the way it sounds with the type r's then cool, if not i'll get 2 mtx 8500's. I know the settings on the jl probably aren't where they should be, I don't know what most of it even means. But the subs don't respond to certain higher frequencies of bass. |

Bronze Member Username: Chuck78Post Number: 70 Registered: Mar-07 | Don't take it too personally Billy, it just gets annoying when people spend $1000++ on stuff and mess it up b/c they don't know what they're doing.. About the box, did someone make it for you or is it a prefab? Here are a few things on setting your gain properly, you'll see a huge increase in performance. Get yourself a DMM at Wal-mart for like $20. http://mobile.jlaudio.com/support_pages.php?page_id=143 That walks you through exactly what you have to do to properly set your gain. http://realmofexcursion.com/ Go to Downloads and download the 50hz test tone. And it's not possible to wire 2 DVC 4ohm subs to 2 ohms, if each sub is wired to 2 ohms then your amp is seeing a 1 ohm load. You'll need to rewire your subs so the amp sees a 4ohm load. Do it like the second picture. http://www.rockfordfosgate.com/rftech/woofer_wizard.asp?submitted=true&woofer_qt y=2&woofer_imp=4 Rewire then set your gain. After you do that set your low pass filter(LPF) anywhere from 80-100hz, more or less turn it a little under halfway up. If all this doesn't work and you have a prefab box, have a custom box made for you, the difference will be like night and day. I'd recommend www.fishercustoms.com |
