Do you even have Speakers and Subwoofers yet? Also, why not just make things simple and get a 5-Channel Amplifier? In your price range, you can look into the Rockford Fosgate R600-5: http://www.sonicelectronix.com/item_34760_Rockford-Fosgate-R600-5.html If you need more power than that, for an extra $50 you can look into the MB Quart ONX4.80/500: http://www.sonicelectronix.com/item_23876_MB-Quart-ONX4.80-500.html |

Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 16 Registered: Nov-10 | I only plan on having those things, but do have a sealed 1.0 cuft box for a 12, thats it, and with a really tight budget, I just hate stock speakers which are 4 6.5", I have a high to low so no need for hu, I have amp kit, so in all reality I need 4 6.5" like 50 wrms speakers nothing crazy just better than stock, and an amp to power those and whatever 12" I get, most likely a svc 4 ohm or dvc 2 ohm so I can use other 2 channels all for as cheap as I can without crappy brands, so u see my dilemma |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1053 Registered: Jun-06 | I personally dealt with MB Quart products and they are very nice. However, I have personally never seen anyone run a 4-Channel amplifier the way you have described. Im sure it will work, but I do not know how good it is overall for the Amplifier, Subwoofer and Speakers. I understand you are working on a tight budget, but allow me to offer you a few suggestions since all you have is the Wiring Kit and Enclosure for a 12" Subwoofer. Amplifier: Rockford Fosgate R600-5 ($249.95): http://www.sonicelectronix.com/item_34760_Rockford-Fosgate-R600-5.html Subwoofer: RE Audio SRX12D4 ($129.99): http://www.sonicelectronix.com/item_27304_RE-Audio-SRX12D4.html Speakers: Pioneer TS-D1602R ($79.99 x2): http://www.sonicelectronix.com/item_11269_Pioneer-TS-D1602R.html Overall total is $539.92. The only way to make this cheaper would be to purchase very low-end Speakers and Subwoofer, or just completely scrap the idea of amplifying your Speakers and just purchase a Mono-Block amplifier for the Subwoofer and run the Speakers off your Decks power. |

Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 19 Registered: Nov-10 | what about the mb quart onnx125.4 170 a 12" dcon or cerwin vega vmax122 130 2 sets of fosgate r1653 80 380 sounds more in my price range i was shooting for 300 350 are you saying that you wouldnt trust the mb quart to run the system i have above. the fosgate speakers i know are sketchy. but im convinced on those two subs, i like the xmax of the dcon but ive heard great things about the vmax's sq and i want an sql setup. i will be adding polyfill to my 1.0 cu ft box. not that i dont believe you but does anyone else agree that it might be harmful to use the mb quart amp this way dcon vs vmax122 vs re sub above which is better suited for the 4 ohm bridged 2 channel load from the onx125.4 i really want it to be loud but not sound like crap doing it. thanks again for all the help. i know i bug sometimes lol |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1056 Registered: Jun-06 | Out of those 3 subwoofers, the SSA DCON would be the best fit with 1.0 Cu Ft enclosure you have, however none of them would be able to be fully powered by the MB Quart ONX4.125. If you were only going to be using 2 of the 4 Channels at 2Ohms for a subwoofer, you will only be seeing 125 Watts RMS. Both the SSA DCON and RE Audio SRX12D4 require 300 Watts RMS, and the Cerwin Vega requires 500 Watts RMS. The only subwoofer I can find that's under $100 that could be powered properly with 125 Watts RMS at 2Ohms would be the RE Audio REX12D4 however, it requires 175 Watts RMS...: http://www.woofersetc.com/p-8394-rex12d4-re-audio-12-250-watt-dual-4-ohm-rex-ser ies-subwoofer.aspx |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1057 Registered: Jun-06 | How about this eddie, lets just simply scrap the idea of amplifying your speakers. You could run this setup below: Amplifier: Kicker ZX400.1 ($169.99): http://www.sonicelectronix.com/item_21954_Kicker-ZX400.1-10ZX400.1.html Subwoofer: SSA DCON D4 ($125): http://www.soundsolutionsaudio.com/store/products/12%22-SSA-DCON-12D4%7B47%7DS4. html Speakers: Pioneer TS-G1643R ($39.99 x2): http://www.sonicelectronix.com/item_20032_Pioneer-TS-G1643R.html#tabs Everything together costs $374.97 which is in your price range. |

Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 22 Registered: Nov-10 | i like the second setup you have there but i was under the impression that the onx125.4 is underratted and i have heard that it would give me a 500wrms in a 4 ohm load using the 3rd and 4th channel bridged on paper so say 75% effieciency thats around 300-400 wrms which would be good for the dcon, i read a blog saying this amp onx125.4 does 1000wrms, it has 3 35 anmp fuses. so it should do 125 x 4 at 4 ohms, 250 x 4 at 2 ohms and 500wrms x 2 at 4 ohms bridged. am i wrong about this specs |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1058 Registered: Jun-06 | Heard its underrated and is underrated are two different things. I would never go by anyones assumption that anything is underrated until you see the bench test results. Also, all amplifiers are not the same, some may put out slightly more/less power than what it is rated for. In other words, two of the same amplifiers may not have the same numbers. That sucks about your previous system not selling. Try putting those up on ebay individually and see if they sell. |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1060 Registered: Jun-06 | You'd be surprised what people will purchase on Ebay and yes, Ebay does get a small cut of the Sale. However, it is a safe way to make transactions online. You could probably sell the Sony Subwoofer for $15-$30 and the Crunch Subwoofer for $25-$40. If you don't want to use Ebay, you can put them up on craigslist and see if anyone will be interested in them. Also, there is no need to sell that amplifier. You could power a DVC 4Ohm SSA DCON at 2Ohms on it. |

Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 29 Registered: Nov-10 | the amp isnt stable at 2 ohms in bridged mode only 4 ohms so i guess i could power a dcon if its the svc 4 ohm. but the amp doesnt push low frequencies to the subs like at all even though my frequency knob is all the down like 30 hz or whatever it bugs me bass i love you doesnt sound like it should ,like when that low fludder hits sub barely moves, no excursion like other vids show, i have it all setup right i just know it has to be the amp, high frequencies have a good punch though like around 55 hz or so tickles my nose. im thinking of using the crunch amp to power some speakers and get a quality deck if i can sell subs and enclosures i have on craigslist. should i adjust some pricing on this at all you think to sell better http://fresno.craigslist.org/ele/2457187722.html |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1066 Registered: Jun-06 | Sorry eddie, that was my bad. I forgot this was a 2-Channel amplifier. I ment to say the SVC 4 Ohm SSA DCON bridged at 4 Ohms. Also, on your listing, I would suggest posting pictures and include the model number of everything your selling. |

Bronze Member Username: Caraudio4lifeClovis, CA USA Post Number: 32 Registered: Nov-10 | for sure well i hope it sells cause im tired of the sq and the loudness of the subs i have thanks again for all your help and cooperation. |
