My model of MX-5 is: NC 3.5 I’m based near: I’m looking for technical help or recommendations on: I’ve bought a used Kenwood DPX 7100 DAB and have it powered up in the car, but I would appreciate clarification of wiring it to the amp so I can hear it. My understanding is that I can power the amp …

The mazda connector works in one of two ways. BOSE systems send line out ( pre-out ) signal through those speaker pins to feed the amp in the back. NON BOSE systems send hi level speaker signal through those pins directly to the speakers. On my install ( Bose ) - I removed the pins from the ISO b…

Thanks, I had read that one, and have seen elsewhere that another pin is required for the Metra connector, but as that post was for an NC2 didn’t know if it was specific to them. I’m a bit hesitant to follow this because I don’t have a single blue wire coming from the HU, but 2 delivering 12V in to…

Just done an NC1 - this may help. The speaker connections shown are pre-out line level from a BOSE head unit. You need the resistor pack or pre-outs from your head unit to feed these. [image]

I would try splicing that blue/white wire (currently connected to the antenna splitter) to the blue wire in the ISO lead. Wouldn’t bother with the antenna splitter, connect the cars aerial to the connection on the HU then get a DAB aerial (stuck on the windscreen) and connect that to the HU. My st…

I’ve read the post MickAP linked to and think I have the same issue as the OP, namely no pin in 1J, which you suggested another cable taken from a new Metra adapter would resolve. Would this be correct? [1000007717] [1000007716] If I do that will I get sound using the ISO connection? I want to …

Thank you again for your help👍 I’ve ordered another cable set. Could you also help with the line-outs sockets to use? Looking at the back of the HU, I think it’s the top 4 to use (top pair Tweeter, middle pair mids?) - are they L & R as you look at them? Which colour wire goes where? I think it’s…

The line out is not split between tweeter and mid/sub - you just feed line level to the amp. All the crossover functions are done in the amp or at the speakers. As the table I posted above - white = left front speaker +ve ( middle pin of phono ) white/black = left front speaker -ve ( outer shrou…

Just had a look at the instructions for your head unit Kenwood DPX 7100 DAB On page 24 you need to set the xover function to NONE so it sends normal feed to the pre-outs Then your phono plugs go in to : Rear right speaker = top left on head unit Rear left speaker = top right on head unit Front …

Thanks again for your help Dean, much appreciated. Probably will find I need to sort out an aerial next to get DAB!

I’ve got it working and I’m happy with the sound. Where you referred to selecting “none” was that for the speaker sizes? From page 6 you can only select either 2 or 3-way crossover type - I think it defaulted to 2 way, which is what I’m using it on. I’ve never had an amp in a car, so the sub menu…
