Tweeter Connector — Circuit Functions

• Pin 1: Speaker positive (+) — connects to the positive terminal of the tweeter
• Pin 2: Speaker negative (-) — connects to the negative terminal of the tweeter
• Polarity matters for speaker phasing — connecting the positive and negative wires in reverse causes the tweeter to be out of phase with the woofer, reducing bass response and imaging. Verify polarity before connecting.

Frequently Asked Questions

How do I repair a damaged tweeter connector?

If the housing is cracked or the latch is broken: replace the housing. Cut the wires behind the damaged connector, strip 6–8mm, crimp new terminals onto each wire, and insert into the new housing. If only the terminals are corroded: extract the corroded terminals, clean the wire ends, crimp new terminals, and reinsert. Tweeter connectors are typically unsealed — they are located inside the door panel or A-pillar trim, protected from moisture by the trim panel.

What contacts are compatible with 174056-2?

Cross-reference 174056-2 in the TE Connectivity catalog (te.com) to identify compatible contact part numbers. Speaker connectors typically use small crimp contacts (0.5–1.5mm² wire range). Verify the contact size before ordering replacement contacts.

Why buy 5 sets?

5-set packs are for car audio installers and workshops that regularly install or repair tweeter speakers. Tweeter connectors are frequently damaged during door panel removal and speaker installation — having bulk stock eliminates reorder delays during installation jobs.

Typical Applications

• Tweeter replacement: Connector repair when replacing OEM tweeters with aftermarket units
