Please help me with my speaker upgrade

Hi all,

I am planning to upgrade my speakers this weekend, and I want to make sure that I am not getting in over my head. I have a 2014 JKU Sport S with stock 130 headunit, bluetooth, connectivity, sirius (no infinity/alpine, etc.).

I want to keep the stock headunit and have no interest in a sub. Thus, after scouring this forum, I decided on and ordered the following:
Polk DXi6501 component speakers (for dash/tweeters)
Polk DXi 651s (for sound bar)

My expertise in car audio installation is severely lacking. I think I helped install a couple of head units when I was in high school, but that's about it. Though I am sure I will regret saying this, I'm not worried about pulling the dash apart or fitting the speakers/brackets. It's the electrical that concerns me. The speakers come with harnesses, so that's a non-issue. The tweeters don't, but I picked up some posi-taps and I can probably figure that out.

My biggest worry is wiring the crossovers that come with the DXi6501 system. I haven't been able to find any write-ups or installation instructions anywhere. If there is a thread out there somewhere, I must really suck at searching.

Anyway, how do I wire/install the crossovers? Do I have to cut the wires coming from the head unit? The idea of cutting wires stresses me out. Does anyone have any pictures of their crossover installation? Any help is appreciated.

Thanks in advance,

Anna

The wires that currently go to the speakers will be connected to the crossover then one pair will connect from the crossover to the speakers and another pair from the crossover to the tweeters. The instructions will have the connections on the crossover labeled.

Thanks.

I'm going to have to cut wires, right? That means I need to pick up some more beer.

No, you don't have to cut. You could get an adapter to plug the speaker wires from the radio into. I wouldn't let that stop you from getting more beer though!

Do tell me more about this adapter. Where would I acquire such a thing?

And don't worry, there is definitely more beer in my future. I have been training my liver for this project all week.

crutchfield has all the adapters you will need. I'm doing the same. Replacing all my speakers. Had them 2 months. Haven't gotten the nerve to partake in this endeavor. Thinking about starting this weekend. It's really not that difficult I just need to make the initial start. Good luck.

Crutchfield sent me adapters from the factory harness to the new speakers, but I don't see anything to use with the crossover. Am I missing something?

I replaced the soundbar speakers last night. I just couldn't help myself. They were sitting there in the box looking at me. It wasn't as smooth as it could have been. I will attribute that to lack of beer and the mosquitos that kept interfering.

Pulling the old speakers and connecting the new ones (using the harnesses crutchfield sent) was a breeze. I had a hard time with the adapter bracket at first. It was a tight squeeze to get the speaker tightened to the adapter with the gasket in between them. I ended up using the vise and making it work. The holes didn't want to line up to the speaker bar at first, but after a stern talking to they caved. Installed with the stock grills.

I played around with the tweeters a bit also, just to get an idea of what I am in for. Maybe a little too much, as I managed to yank the wires off one and had to enlist some help to resoldier (or is it sauter?) them. I knew that I was going to have to trim the tombstone housing to get them to fit, but after looking at it I'm a bit nervous. I would love to have the flush mount fit, but the flush mount ring looks way too big for those housings. The surface mount would work, if I could get just the top ring to protrude (almost like a flush/surface mount hybrid?). Otherwise, I feel like it would stick out too much.

FWIW, I don't think the DXi stuff was worth the extra $. If I had to do it again, I would get the DB series stuff. At least you have the option of using the polk grill with the soundbar speakers (not that I would have, but options are always good!). I went with the DXi because I liked the look of the all black tweeters. After all, those are the only ones you will really see, right?

If you are putting components in the front then you cannot use the standard speaker wire adapter that they include. Honestly the easiest way to to just bite the bullet and and cut the wire going into the woofer "pod". Then you could run the wire into the crossover and then run another back into the pod for the woofer. If you really don't want to cut any wires then you could use the taps that you have also. Basically you would unplug where the harness from the pod and then tap off of that and run it into the crossover. Then you would have to run a new wire from the crossover into the pod to connect to the woofer. On the back of the pod there is a rubber plug that the factory wires go into, you would have to either tap back into these (which I'm not sure if there is enough room or not) or see if you could run the wire either along side the rubber plug of drill a new hole through it or even remove it all together, I'm not sure if it would affect the sound with it out.

If you were using coax speakers as you did in the soundbar it would be just as easy as plugging in the adapter like you did for the other ones, but coax in the front are pretty pointless since they are basically pointing at your knees and not your ears.

Hopefully that will give you a better idea of how to connect them. Once you figure out how they need to be wired it's not that difficult to see how you need to connect them.

Also, the dxi and db series are almost identical to each other and can usually be found for the same price as one another.

I was able to get it done this weekend. Only took 6 hours.

I ended up tapping behind the harnesses for the input into the crossover and from the crossover to the woofer. I ran out of taps, so I did have to cut the driver's side speaker harness. I just left it hooked to the back of the speaker box, so it should be a quick fix should I ever have to go back to stock. It wasn't nearly as painful as I thought it would be.

I also chickened out on cutting the tweeter tombstones and opted for a surface mount instead. It sticks out more than I would like, but the black grill makes it look like it belongs there. The hardest part was fabricating something for it to mount to. I found a 1 1/4" knock out seal at HD (Raco 1-1/4 in. Steel Knock-Out Seal-1045-25 at The Home Depot), pulled the prongs off, and drilled two holes - one in the middle for a screw to connect the surface mount housing and a bigger one above it to run the tweeter wires through. Worked like a champ (and was cheap). I'm sure there is a way to push the seal in through the front of the enclosure and have it lock that way, but that would likely involve some trimming of the housing. Instead, the pulled the seals up from the inside. This would have been much easier with two people.

Overall, it was fun to get to know my jeep so intimately this weekend. Took longer than I thought, but I'm happy with the results.
