Customer Q&A

2 questions already asked

I installed an aftermarket stereo that has a harness port that allowed me to use the existing wiring (with an adapter) to connect to my door speakers. The stereo also has front/rear pre-amp outs. My Honda Fit LX is not equipped with tweeters. Am I able to connect these Kicker tweeters to my stereo using the pre-amp outs while simultaneously using the stereoâ??s internal amp to power the door speakers? Is there a different way I should be thinking about it? The stereo unit is the BOSS BE7ACP.

The pre-amp outputs on an aftermarket radio are not intended to directly power speakers, but are instead used to send signal to an aftermarket amplifier that would power speakers. Our advisors would be happy to discuss options for connecting these tweeters to your BOSS radio. Please give us a call at 1-800-324-9695. We're happy to help!

How do these connect to existing wiring?

They already have the metal tips that slide onto the speakers + and - on one end of the wire, and conveniently enough on other end of the wire they have metal adapters that the factory speaker wires that you took off factory speaker slide into. That's if I remember correctly. But I'm almost positive it's 100% plug n play, no need to cut any wires, and no need to add on your own little metal speaker things that slide onto + and - (sorry drawing a blank on what their called) to speaker. They pretty much have a patch cable with the metal things on both ends so factory wires that you take off speaker slide into one side of wire, and other end of wire has metal things to slide onto + - of speaker That you took factory wires off of. Hope it makes sense. Either the wiring is cake no matter how it was, these were marked as not even not fitting my truck so I just added on 2 metal back straps, custom mounted in factory spot and the wiring took no time

Nowhere on the box nor the paperwork does it show you , but the wire with the black strip is negative.
[ Edward  Mar 31, 2021 ]
Each tweeter has about a 4 inch piece of pre-soldered wire to it with ends that connect to the wire that also comes in the box that has the inline capacitor/ barrel type crossover. Connect together and cut the excess wire to your desired length to attach to your existing wire. Great mounting options. P.S. The tweeters sound great !!! Not dull and low and not loud and harsh but really noticeable... About Perfect!!
[ Edward  Mar 31, 2021 ]
Well I had bought 2 way 6x9s and it didn't have the highs that I wanted compared to the Components up front 6 1/2 door and 1" tweeters. I hooked up the new tweeters to the rear channels of the 6x9s which is being run by the new Kicker CXA 360x4.. technically it would bring the ohm load to low by hooking up so many speakers but it didn't come down maybe a .5 ohm not even 1 ohm! I mounted them in the rear pillar post of the car. They came with a great crossover so it worked out really well! Thanks to Crutchfield and all the help that they gave me!
