Looks like a Heath Robinsons attempt to construct a bluetooth / Radio amp?.

Has it got a non standard head unit, those twisted pairs of wires look like the speaker wires that come out of the original amp, that looks like a basic amp setup maybe...

Finding that must have been a nasty surprise If I were you I would make sure you carry a fire extinguisher. |

Passive crossover for the speakers. Allow connect and split signal to different speakers from single output from amplifier.

I agree with Jimmie, it looks like a passive crossover for the speakers. Ron B. VK2OTC

Looks like it's a crossover then, whatever one of them is!!! I know little about ICE, I do know those wires are the speaker wires coming from the original amp, I cut them from the plug and wired them directly to the new head unit that had a built in amplifier.

A crossover splits the sound frequencies so the right frequency range goes to each speaker. You don’t really want low frequency bass being sent to a tweeter, or treble being sent to a subwoofer. They can’t produce the sound. The original system used an active system, so the crossovers were in the BM54 amp, and the circuits powered/driven by the 12v feed from the car. This makes the system much more efficient as all the amps power can then be used to drive the speakers. In a more normal passive system the crossovers tend to be on each speaker and the amp has to drive the circuits too, taking quite a bit of its power output and increasing its load.

I get radio noise like when the antenna isn't connected, so i know its connected, i was going to take out the crossover, because its a mess, but if i disconnect it, what would i have to use? |
