Asked on diy audio across the pond and been told to place a 100uf NP electrolytic cap in series with the door speaker so the amp only sees the sub 4 ohms
The hand drawn is how the speakers are connected in the car factory fit
The other 2 channels feed the rear speakers so already being used
just need to get the impedance up from 2 ohm's to 4 ohm's so the amp won't distort
the schematic is what i intend to do
the amp is a Vibe powerbox 65.4
cant...
I have bought a little micro class D amp for my car 4 x 65 w rms
the amp connects to the speaker outputs on the head unit then boosts the output to the speakers the amp is 4 ohms stable

Looking to build a M/M phono opamp version
what would be a good schematic to use ?
quite a few pcb on ebay and alibaba
but dont mind making it on veroboard
my cart is a 2M Red
After opening up i realised you can only ajust the bias so i set that to 34.5ma
53v at the front end after VBE and 45v at the output stage
giving me 27v into 8R dummy load = 91watts
just before the sine wave started to sqare off
