Hello guys, i have to install my new speakers and tweeters on my e46. The original speaker have 2 jacks to power the speaker and tweeter. Now, my aftermarket speaker don't have that, only + and - . I don't have adapters and for these jacks so i need to cut them and install. If i'm wiring the tweeter to power it from the speaker it's ok ? The speaker is 4ohms like my speakers. I have to wire them in series or parallel? I hope you understand
