  1. Power connection from amp to Battery Lead turn on from amp to the Red/Blue (which is the swithced wire) wire in Socket 2 Ground from amp to vehicle chassis Splice in speaker wires- Is this correct?
  2. So, you think it's safer to splice into the brown ground wire instead of running the ground wire with my new wiring kit directly from the ground output on my new amp to the battery? And I'm kind of stupid on this, but what's the difference between the switched and unswitched wires?
  3. OK.. So let me make sure I've got this right... Socket 2 is the output harness (the bigger one). I would connect the turn on wire from the amp wiring kit I bought to the Red/Blue wire from socket 2 and connect to the new amp. And if I run a new ground wire from the new amp to the vehicle chassis, I don't have to do anything with the Brown Ground wire in Socket 2. And would I have to do anything with the Black/Red +12 switched wire coming from the radio? And since I don't have rear speakers, the Red/Blue wire in Socket 1 is not used either? Thanks for all your help.
  4. Which one is the lead turn on switch for the amp? Assume if you're using an amp wiring kit, you don't need to fool with the black/red and red/blue wires, right? Just run the power to the battery, ground to chassis, and hook up the lead turn on?
  5. Yes, Red/Blue... There's one on both the input harness and output harness.... How about that light brown wire on the output?
  6. Installing a new amp to replace the factory Nokia... Can anyone tell me what the black/red wire and the blue/red wire is on the input harness? And also, what is the red/blue wire and the brown wire on the output harness? Thanks for the help :cheers:
  7. Thanks Cassiebox- Do you know which wire color coming from the Becker head unit is the remote turn on, power, and ground? Thanks for your help.
  8. OK.. Think I'm square on the input & output harness in terms of which wires go with which speaker... But, another question... When you add an aftermarket amp, you have to run the power, ground, and turn on (remote) wire to the amp. Since this thing already has a factory amp in it now, are these wires not already present and can you use them or do you have to buy a separate amp wiring kit to hook up power, ground, and turn on wire? Also, I noticed in the input harness at the amp from the Becker, there was a black/red wire. Anyone know what this one is?
  9. Here's the link to the PNP harness for the THA 475 PNP amp http://www.crutchfield.com/App/Product/Ite...015&tp=6348 And here's the extension to run the wiring to the front or rear trunk area... http://www.crutchfield.com/App/Product/Ite...amp;i=023THA25M These two harnesses and one of the THApnp Blaupunkt amps are all you need... No wiring, no splicing, no running new wires... Everything just plugs into existing wiring from your factory head unit, usually the Becker CDR220. The only thing I'm not sure of is how you run the extension harness through the firewall... Anybody know?
  10. OK.. If the larger one is the speaker output harness, what's the small one that plugs in the factory amp?? Is that speaker input harness that comes from the back of the factory Becker head unit?
  11. smaller plug at amp is input from h/u - larger one is output to speakers. IIRC there are some nuances by MY so best to reference Bentley manual for correct MY pin out. I'll check mine for you if you'd like. That would be great... Thanks.
  12. Cassiebox- Actually, I have already upgraded the factory speakers. Put new Alpines in both the dash & door. But with the factory amp still in, they sound as crappy as the factory Nokia speakers that came out. That's why I want to replace the Becker CDR-220 with a higher powered head unit and wire the speakers directly into it and bypass the amp. Any advice on hard wiring? Which set of plugs at the amp location go to the speakers?
  13. There have been many topics about upgrading the factory Becker head units with aftermarket, more powerful CD players. My question is has anyone bypassed the sorry factory amplifier and hard wired the dash & front door speaker wires directly to a new head unit?? I've read where if you upgrade the head unit and all four speakers, but still run it through the factory amp, you can't tell much difference in sound quality. But, if you run the speakers directly to a higher powered new head unit, the sound is dramatically improved... Has anyone done this? Any help on how to do it would be grea
  14. Try Crutchfield.com They sell wiring harnesses for almost any type of car.
