Aftermarket rear speaker wiring trouble
08 Gt G6 Monsoon audio system.
I recently blew my right rear tweeter so I decided to replace both speakers with 3 way aftermarket 6x9 kickers. I bought an adapter from best buy that was recommended for my car. After installing the rear speakers I went to simply plug in the adapter to find out it was not the correct one. After researching further I cannot find an adapter that will work with the monsoon amp. For some reason the amp has a positive and negative wire, but also has 2 extra wires that run to the stock tweeters. My aftermarket speakers, like most other speakers, only have a positive and negative port without separate tweeter wires. I cut my factory adapters thinking I could just connect the positive speaker and tweeter wires from the amp, with the speakers positive port and the same with the negatives. But when I connect the wires the speaker seems to be overpowered and shorts out and sputters. If i only connect the tweeters they work fine and if I only connect the bass speaker its fine, but they will not work together.
I've talked to multiple local professionals and they have no suggestions and I cant find anything online. I do not want to pay someone to do this b/c i have already installed them, its just the wiring.
