The other problem is what amp to power these subs? I was looking at this configuration to save money. will it work that my question> two mono sony XMD-500X's there spec - Channel Configuration: 1 (mono) Low Pass Filter (selectable): 50-200 Hz Output Power DIN 45500: at 4 ohm 1 x 250W (14V, 100Hz), at 2 ohm 1 x 500W (14V, 100Hz) Output Power Rated/THD: at 4 ohm 1 x 250W / 0.2% (14.4V, 20-300Hz), at 2 ohm 1 x 500W / 0.6% (14.4V, 20-300Hz) Output Power Maximum (14.4V): at 4 ohm 1 x 600W, at 2 ohm 1 x 1100W Frequency Response: 5-300Hz (Tolerance: +0.5/-3 dB) Signal to Noise Ratio: 100 dB Total Harmonic Distortion (1 kHz): <0.04% (14V, 100Hz) 4-rail Power Supply 2 Channel Speaker Level Input and Line Out MOSFET: Output Stage/Power Supply Bass Boost: 40Hz, 0-10 dB Toroidal Transformer Line In: Input Sensitivity 0.3 - 6V Gold Plated Connectors Load Capability: 2 ohm Current Drain (rated output power at 4 ohm): 50 A Weight Approx 3.3kg Dimensions (W X H X D in mm) approx 388 x 53 x 268 The question is the sub is at 4 ohms. will this amp work as it is 1x600rms at 2ohms stable? |

You can wires both subs into that amp. Two 4 ohm subs wired in parrallel will give you a 2 ohm load. Perfect. |

New member Username: KaramPost Number: 3 Registered: May-05 | lol, yes i understand BUT, the problem is can i wire one sub(4ohm svc) to 1 amp which gives 1x600rms at 2 ohms as the amp only give out 600rms. so if i buy two amps and use them on each sub. |

Sony needs to stick to Tv's. They basically build crap and put the sony stamp on it, and expect people to buy it. I would wire the subs together in parallel (connect both pos together and both negs together and then connect the amp.) giving you a 2 ohm load. Then either get an amp that will give you 1200-1500 watts rms at 2 ohm. It will be cheaper to get one large amp than 2 small ones. Then as far as the box goes, talk to Subfanatic. he builds custom stuff. |

Bronze Member Username: Virus5877West Lafayette, Indiana USA Post Number: 71 Registered: Apr-05 | Ok, here's what you should do, return the subs for the dual 4 ohm voice coil version. should be the same price, if not, it will only be a few bucks more. Then go here: www.onlinecarstereo.com get the PPI DCX 1500.1 amp, it's 1500 watts at 1 ohm. and it's only $500. You will be bumping with the best of them. |

New member Username: KaramPost Number: 4 Registered: May-05 | the thing is i cant return the subs as i got them from ebay. there was a deal buy one get another free so i got them. the other problem is that i live in the uk. i got the subs from usa as they were alot less money. so could you tell me what is the best amp to get for those subs and value for money. if you can find a shop in usa which will ship to uk could you let me know and if they do the amp i could get it from them. |
