Upgrading your tweeters is usually pretty easy. I mean, unless you’re doin some kinda fancy pillar pods or something. If you’re lucky, your new tweeters will fit right where the old tweeters used to be, using the preexisting wires.
This handy guide will help sort out some of those frequency… err frequently asked questions.
First up, what the heck is the polarity of these gosh darn things? On BZRK Audio tweeters, the wire with the marking is positive.
It’s hard to see the marking on the RS-T150 tweeters, but if the lighting is right and you squint a bit, you’ll see some text on the wires. On RS-T150 tweeters, the wire with white text is positive.
On SQ-T100 tweeters, the wire with the red stripe is positive.
On your bigger speakers- the woofers and such, you might be lucky enough to find polarity marking on the terminals. Otherwise, on woofers, the larger terminal is usually positive.
On speaker wiring in general, the wire with the line is usually positive. Red wire is usually positive, and black wire is usually negative.
If your door speakers are receiving full range signal, then you can wire your tweeters directly to the door speakers. You can also connect to the speaker wire anywhere in between the door speaker and your amplifier/radio.
Always use a bass blocker, or else your tweeters will smell funny and sound bad, or worse, they could let out the magic smoke and then they won’t make sound at all.
With the bass blocker installed, your tweeters will have very little impact on the overall impedance that your stereo sees. The image below is from our guide to wiring in series/parallel.
