replacing speakers in front of 1999 camaro

i have a 1999 camaro with the monsoon AM-FM stereo with CD player and automatic tone control. i have bought a pair of infinity 652i 6-1/2 inch speakers. the factory speakers had two sets of wires going to each speaker, and the new speakers have only one set of terminals for the wires. the wires coming from the radio to the speakers are purple , dark green , light green and .orange. these connect to a set of wires that are two sets of red and black.  will i connect  the two sets of wires to each terminal or what. thank you for any help! dstter

I have a 98 trans am with the same system. From all the people I've talked to It seems that the best solution is just to go ahead and put in a new Head unit. Monsoon systems are odd as far as wiring goes and seem to be designed for the sole purpose of complicating upgrades(they openly discourage them on their website). Replacing 1 set of speakers in a monsoon system may actually sound worse than just leaving it alone due to problems of impedence and power output from the factory unit. Best bet is to replace the whole thing.Of all the things I've lost I miss my mind the most.
