THanks robert |

Installing isnt hard its all color coded and all you really need it adapters and wiring kits/harnesses. Since this is your first system im goingto give you some advice and let you pick out some amps then come back here and ask which of the amps you picked are good. First thing: Mono amps were made for subwoofers. Second: How many voice coils do the subs have? 1 or 2 (SVC/DVC) Third: The wattage of the subs. Fourth: Class D amps are very efficient and dont get as hot as AB amps. Fifth: What impedence rating do the voice coils hav (each). Itll be in Ohms which has a horseshoe for a symbol. Sixth: This link to a bunch of wiring diagrams http://www.crutchfieldadvisor.com/S-H1OrjgFRAMj/learningcenter/car/subwoofers_wi ring.html Seventh: When picking a wiring plan remember that most of the time you can get a less expensive amp if it is running 2 or 1 ohms. So using this info you can find an amp. In the wiring diagrams the little ohm rating on the left of each picture is what your amp would be running for ohms. You want the amp wattage to be atleast 70% of what the subs can take. Example: Im getting two OZ Audio Vector2 Subs. They are single voice coil. The voice coils are 4 Ohms each. The subs are 250 RMS each. I chose to wire them in parellel which would give me a 2 ohm setup. So the amp I would chose is a MTX Thunder 801D Which is 500W X 1 @ 2ohms Hope this all helps "Give a man a fish feed him for a day, Teach a man to finsh feed him for a life time" |

That way your stock component speakers can just play treble (they do good at that). Then later you can put in a nice head unit, and later on you can install different component speakers. This works the best. Because you wont really see any improvements in sound quality installing a deck. But if you put in a sub, amp, and box you will notice a big change. Then the rest from there is to make it look good. |

Silver Member Username: GrmncrsnbrVA Post Number: 129 Registered: Jun-04 | according to MTX's website the Thunder801D puts out 500X1 @ 2ohms with a 12.5v source oh and whats a birth sheet haha |

Silver Member Username: JayjLouisiana USA Post Number: 286 Registered: May-04 | The birth sheet is the paper they put in the box with the amp after they TEST the amp. And one other thing MTX does NOT ship an amp if it isn't doing at least the RMS most of their amps are 20-60 watts MORE then the RMS so this means their UNDERRATED so if they aren't doing 600 watts RMS at 12 volts they WILL be at 14.4volts. Good Luck |

Silver Member Username: JayjLouisiana USA Post Number: 288 Registered: May-04 | Naw man you can still use it. They are VERY good amps. You MAY have to turn the gains down alittle but nothing major. Plus one other big thing about them is they tell you the RMS at 12volts. You will only have 12volts to it when the car is off when your driving down the road you will have 13.8-14.4volts so this will boost the RMS also. But all you have to do is turn the gains down and you will not have any problems. Good luck hope this helps. |

Silver Member Username: Davids2004Houston, TX USA Post Number: 233 Registered: Jun-04 | Go with 2 S12L7 ported and run them of a hifonics bx1500. Make sure to get dvc 4 ohm and you can run both subs to 1 ohm and get 1500 rms out of that amp which will give ya 750 rms per sub. That will pound. |
