New member Username: Jgkc9aycIL USA Post Number: 2 Registered: Feb-08 | I just got a 2002 Pontiac Grand Prix GT. It doesn't have the Bose stereo, but it does have the OnStar as well as steering wheel controls. My budget forbids me to replace the dash unit at this time, however I have the 5 1/4" & 6x9" speakers from a previous install as well as a 4 channel amp (RF 200a4) & a 2 channel amp (RF 200.2) and an old RF sub (Punch DVC). Is there anyway I can hook up my aftermarket speakers to those amps as well as the sub & leave the factory head unit & still utilize the steering wheel controls & the OnStar? If so, what do I need? Thanks in advance. |

New member Username: Jgkc9aycIL USA Post Number: 3 Registered: Feb-08 | I don't think i'll tackle it myself. Crutchfield said i'd have to tap into the wiring harness to hook up the line out converter. I was hoping there'd just be an adapter of some sort I could get to plug into the existing harness. I was also told in order to hook up the sub amp, i'd run an rca cable from the outputs of the 4-channel to the inputs of the 2-channel. Is this true? |

New member Username: Jgkc9aycIL USA Post Number: 5 Registered: Feb-08 | What about what Crutchfield told me about having to tap into my existing wiring harness...is this true? I'll still need to run new wire from my amp to my speakers, won't I? |

Silver Member Username: MmaudioconceptsPost Number: 381 Registered: Jan-07 | cheap LOCs have a voltage of 2Vmax not rms and dpeending on which one he gets it might be way below 1V rms. I have seen major differences in sound just form a Line driver. JL sells a line driver that has two inputs and 7V output. |

New member Username: Jgkc9aycIL USA Post Number: 6 Registered: Feb-08 | "JL"? So i'd need a LOC AND a line driver? |

Silver Member Username: MmaudioconceptsPost Number: 382 Registered: Jan-07 | you dont have to have it, MS is right, but i have perosonally seen differences and the line driver can be found on ebay for like $43 |

Silver Member Username: MmaudioconceptsPost Number: 384 Registered: Jan-07 | yes u will have to tap in to the wires or u can tap in to the speakers in your rear deck. and yes u will still have to run wires from amp to speakers |
|
New member Username: Jgkc9aycIL USA Post Number: 8 Registered: Feb-08 | So the LOC requires me to tap into the wires going to the speakers, yes? It doesn't matter whether it's the front or rear? What about hooking up the 2nd amp for my sub? A friend said I could go from the rca out on one to the rca in on the 2nd...Crutchfield said i'd need a "Y" adapter. Which route is best? |

New member Username: LoudazzaltimaBrooklyn, NY Post Number: 2 Registered: Mar-08 | most amps have a output line just so u can split the signal , but using a y adapter is the same, but i strongly suggest on gettin a aftermarket radio in the future, the sound quality wdifference will be huge |

Bronze Member Username: SuperroberPost Number: 47 Registered: Jan-08 | I tried both options and at the end my factory head unit sounded a 100 times better than an alpine 9885. I never knew why. With the alpine radio I had to turn the volume to the max and sounded as loud as my factory head unit at 50% volume. I tried changing settings and gains but nothing. |
