Got a set of 4 JBL 6420 speakers to replace the original Blaupunkt setup which have disintergrated over the last 30 years ! They fit perfectly once the plastic surround has been removed. So, the old speakers are connected via the original t-block to a plug that is fixed to a spade and each side soldered to 2 fine wires that head off to the cone. I want to reuse these if possible as it makes life simple BUT I don't know which way round I need to connect to the new speaker - here's a pic.
Theres a large and small spade - question is which wire coming into the t-block would go with which spade??? Here are the old speakers with the receptor I want to reuse.
and here is the cabling feeding the t-block
Any help appreciated - TIA
