I’m new to this forum and also new to car audio. I am still learning as much as I can.

I am building a sound system in my 2015 Harley Street Glide. I am running:

2- 6.5 inch speakers in the fairing – wired directly to the Sony AX7000 deck
4- 6×9 Polk Audio (4-ohms each) wired in series/parallel to:
Soundstream PN4.1000D 1000W 4-channel Amp with a 4 ohm rating of 140w x 4 channel

I was able to get everything working properly by wiring the 4 6×9 speakers in series/parallel, similar to the image attached:

I am happy with the sound, but I want more highs. To do this, I ordered 4 4-ohm super tweeters (DS18 PRO-TW220) at 225W RMS.

I ran them similar to the 6×9 speakers in series/parallel (since they are all 4 ohm resistance) to the “front” portion of the amp. The “rear” portion of the amp is running the 6×9 speakers. However, I am not getting any sound at all. The 4 tweeters come with capacitors built in. So, I was thinking about tapping into the wires for the 6×9 speakers to run the tweeters, but how would I do that without affecting the impedance? Where would I connect the positive and negatives to exactly?

Again, I’m brand new to all of this and refuse to pay someone to do this as I want to learn myself. Thanks.
