Carver DSP Amp & Stereo Delete
Hey, guys. Purchased a used 2003 Z4 3.0 with navigation. Car was delivered without the nav unit and the amp is waterlogged and practically useless.
Decided to replace the amp and stereo with aftermarket. Do I need to re-run all wiring (Amp, speakers, head unit), can I use existing wiring or will it have to be hybrid? I'm a noob when it comes to audio tech, but I can follow instructions well enough. I was able to update the OEM stereo to aftermarket stereo in my 2004 Z4 2.5 without much issue a few months back. Thought this was going to be as easy... Also, any suggestions on amps? Don't want to over or under spend. Last edited by jharris344; 01-25-2022 at 07:50 PM.. |

Diving in!
OK, so I bought a Planet Audio 5 channel amp (AC1800.5) and a wiring kit to go along with my Boss HU (BCPA9). Have the same HU in my 2004 Z4 and I like it. Going to try to wire it all up this weekend.
I'm going to first attempt to use the current wiring guide found at the link below to connect speaker wires and power. Worst case scenario, I have to re-run speaker wiring, power and signal from HU. Best case, I only have to re-run signal from HU. Worst-worst case, nothing works either way. Going to test by running power to amp, wiring up the speakers and running signal from HU to amp over the back seat and into trunk. If it works, then I'll proceed. If not, then I'll regroup. I'll keep you guys posted. http://www.billswebspace.com/A18%20Amplifier.htm |

If you have replaced them with aftermarket then disregard.

I kinda figured as much. The amp I bought runs at 2 or 4 ohms so I'm hoping it'll work with the current setup (assuming I set everything up correctly). If not, it's a short drive to my local auto stereo store. I bought 4 aftermarket speakers from Crutchfield, but after looking at the specs they too are 4 ohm. Hopefully, I can use them. If not, I'll return them and get something else.

OK. Took me a bit to figure out my amp wasn't grounded properly, but a bit of success.
1. The Planet Audio 5 channel amp (AC1800.5) is HUGE!!!! Was too busy looking at the specs to think about the dimensions. Unless you don't like trunk space get a smaller amp. 2. Going to have to run RCA and remote turn-on cabling from HU to amp in trunk. 3. I'm able to use existing wiring in the trunk so won't have to rewire speakers from amp. Can just use existing. 4. Using a Metra wire harness for just power, accessory and remote turn-on. So far everything has been super simple. Plan on finishing my test run tomorrow by wiring up all speakers to the amp. If everything looks good I'll start running the RCA and remote cabling from the HU to the trunk. |

Was able to run my wires from the trunk to the dash and connect to HU. HU and amp are pretty much set up. Just have have to wire them to the speakers and I'm done. Will finish up during the week because it's getting cold again here in Orlando. No bomb cyclone, but it was 39 this AM and not it's in the low 60s!!! Parka and chili time.

Pics of Progress
Here are a few pics of my progress. Still at the point where I need to start wiring the speakers to the amps. Hopeful that I can get this completed this by the weekend. Still have a bit more cleanup to do as far as hiding the wires and securing the amp. But, can worry about that after everything is wired.
Then on to my top replacement. The updates seem never ending. LOL. |

The electronics geek in me wants to scold you for apparently not knowing what a soldering iron is. But this is a very ambitious project so I'm letting it slide. Still, some solder and shrink tubing might be something to consider investing in.

LOL. I was hoping someone would pipe in after seeing the photos. Great idea. I have a soldering iron lying around somewhere and I'll grab some shrink tubing from AMZ or Lowes. Might redo my other Z4 as well. I'm using wire caps there as well.

Nice work-I wish i had the energy to do that!
You should do a blue bus install while it's torn apart.
