2012 non infinity front speaker install question

Right now I have the non upgraded sound system in my 2012 unlimited. I replaced the soundbar speakers with polk dxi651 speakers and now I'm putting in the polk db6501 speakers in the dash.

My question is how do I wire these crossovers? I am going to have a shop install an alpine power pack amp in the next coming weeks but I wanted to install all the speakers myself before I brought it in. So do I use the crossovers? If so how do I wire them? Again not factory amplified system.

Look at the Kicker 77kick10 speakers. They are an upgrade speaker that plugs right into the factory speaker wire harness. They are made for your vehicle. I have replaced my dash and sound bar speakers with these and they sound great. I paid $68 for a pair on EBay

Connect the wires that go to your speaker to the cross over input. Then connect the woofer output to the new woofer and the tweeter output to the new tweeter.

Cool thanks. I got it now. I got the harness connectors from crutch field so I was confused when I didn't need them. I just cut the stock woofer connector off, hooked that to input and then ran new wires to new tweeter and woofer from the crossover. Sounds great!!

Now when I get the alpine power pack installed I can just have new wires ran to the crossovers in the front and it will sound even better.

I installed the Alpine power pack and it does improve the sound.

I installed those speakers with the alpine power pack.

It's really quite easy to do. Just hook the output of the power pack to the input on the crossover. Wire the tweeter to the tweeter output and the woofer to the woofer output and enjoy.

Be sure to dial it in so you don't get distortion. You'll be surprised at how loud you can get with such a small amp.

Did you run a direct power from the battery for the power pack? I thought about installing it myself but didn't want to screw anything up. Did you follow any write up?

I've been a shade tree mechanic for decades and I'm an engineer so I didn't follow a write up. I did my own planning and installation.

I did run a direct feed power wire from the battery for my two power packs (one for the 4 regular speakers, one to run a dual voice coil subwoofer), the CB radio and a couple of other things.

Really, all you need to do is to hook up a wire to the positive terminal, put a fuse in it right there at the battery, run the wire in through to the dash and connect it to the power pack. Attach a ground wire to a convenient spot under the dash. Wire up the rest to the radio (an aftermarket harness adapter makes life so much easier) and you're in business.
