New member Username: StevestewaPost Number: 7 Registered: Dec-05 | Ok, here's my situation. I just bought 2 10" mtx 8500's and an mtx T7801 amp. My problem is that the subs I bought have a 4 ohm load instead of the 2 ohm load that I meant to buy. At 4 ohms the amp doesn't put out nearly enough power. My question is should I just exchange the subs for the ones with a 2 ohm load or would there be a big enough difference in SQ and SPL to justify upgrading to an amp that will put out enough power for the 4 ohm subs? |

Gold Member Username: AraknidBOCA , FL U.S. Post Number: 1422 Registered: Nov-04 | I found this info on the amp and says it puts out 600 watts at 1 ohm. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem%26item%3D5840372356&category=64573 If those are DVC 4 ohms then they will work perfect. |

Bronze Member Username: Ruxpin20DeTroiT, MIchiGan Post Number: 27 Registered: Oct-05 | The wiring options for the DVC would be 4ohms and 1ohms (at 1 ohm your amp puts out 1200 watts with 14.7 volts going to it) the wiring options for the SVC would be 2 ohms and 8 ohms. here are all the links, http://mtx.com/caraudio/products/subwoofers/thunder8500.cfm http://mtx.com/caraudio/products/amplifiers/thunder7801.cfm http://www.rockfordfosgate.com/rftech/wiringwizard.asp?WoofQty=2+woofers&WoofImp =Single+Voice+Coil+-+4+ohms&image.x=17&image.y=13 |

Gold Member Username: AraknidBOCA , FL U.S. Post Number: 1424 Registered: Nov-04 | Well the guy on ebay said the RMS was 600 watts x 1 @ 1 ohm. So if he does have the DVC 4 ohm subs he can wire them to a 1 ohm load and get 300 per sub. |
