HELP - installing new speakers at this moment.

in a 2013 JKU i'm installing speakers in the sound bar and front dash.

Question: in the sound bar i unhooked the & have to cut them to hook up my new kappa infinity speakers.... Is the black wire + and green wire - ?

Question: the front speaker - are the wire colors the same? if not, which is + and which is - ?

low end system, no alpine upgrade.

I don't remember the colors...but do a search on here. I know there is at least one thread on here that shows the colors of every wire in the Alpine system. Crutchfield has adapters that are just plug and play...no wire cutting or splicing. I'll look...may have a good thread saved in my favs.

I don't remember the colours off the top of my head, usually a pair will be the same colour with the -ve having a stripe but of course Chrysler will do something different, because god forbid they might actually make life easy for us.

If you don't have clear colour coding, just wire each speaker up in turn and turn the stereo on. If the sound is muddy and distorted, it means the speaker is running out of phase (i.e. it's doing the reverse of what it's supposed to be doing) because you got them the wrong way round. You won't damage the speaker by wiring it out of phase briefly. Reverse the connections, test sound, move on to the next one and repeat the process.

green wire is solid, black wire has a white stripe in it. And i do not know what "ve" means? (it's kinda comical, my dad was an electrical engineer. LOL) called him, he wasn't sure either.

Sorry, -ve is a lazy short hand for negative (as opposed to +ve).

Solid green and black with white stripe? Honestly no idea. If you pushed me I'd guess at black/white being negative, but it would be a guess based purely on the fact that a stripe is usually negative in speaker cabling. Like I said, wire it up and see. As long it's definitely a speaker wire you've got in your hand (i.e. it came off the previous speaker, and you're not accidentally tapping into the power cable for the overhead light) you won't do it any harm if you get it the wrong way round, and you'll immediately be able to tell it's wrong when you turn it on.

A little research takes less time and effort than trial and error. Colors of wires to all 7 speakers are listed in the link I posted above.

OOPS...non-alpine system...Never Mind!

Correct. Speakers aren't fused, all that happens when you get the speaker wired the wrong way is that it runs "out of phase" - because you reversed the polarity, the electromagnet that is the heart of the speaker does the opposite thing i.e. it pulls the cone in rather than pushes it out. The sound will be very unclear, and if you watch the speaker you'll see that the cone is being sucked in and released rather than pushed out and released. If you ran a speaker out of phase with a lot of volume and the bass pushed right up on the EQ then you could possibly do some harm to the cone, but you're just testing it - you won't do any damage.

They are, but that's an amplified system. I don't see a pair on that link that corresponds to the pair that OP describes on his non-amplified system, or even anything close.

Personally I'd be inclined to use adapters on the Chrysler plugs rather than cutting the ends off, but if OP has already done the cutting then it's kind of what he has to work with now.

i bought infinity kappa's they have a collector, to which you have to cut the stock connector off, and then slip in and clam down a screw for the new speaker.... and my system is bottom end, no upgrades.

If you haven't cut them yet, I'd still be inclined to use an adapter harness like this:



If need be cut the spades off there, that way you can keep the stock wiring intact.

Check polarity with a battery and your wires if not sure which wire is + or -, other batteries will work, same principle:



Wiring "out of phase" shouldn't hurt anything, but should be evident by the sound that it is wired wrong.

Polarity on speakers doesnt matter as long as theyre all hooked up the same.

I would never reuse factory speaker wiring anyway. Upgrade to 14 gauge wire. Lasts longer.

Since you went Infinity...did you go 2 ohms?

(And yeah, the adapters are good things indeed).

Infinity aftermarket speakers with the 2ohm voice coil you are talking about... right? I was looking at those, not sure if I'm going to do anything with my stock stereo right now. If I do I'll just replace everything.

Since you found the answer would you mind telling us that are about to do this job. I'm expecting my Polk to arrive tomorrow.

Simple answer - if you're re-using the stock wiring, and there's no reason not to, then use the adapters as described further up.
