Help with installing components front and rear

[Jojo_Gutts]

So here is my prob. I recently got my hand on two pairs of Jbl component systems. The JBL club 6500c and the JBL stage 6000c. I want to put these in my car (nissan versa note sv 2014) since my stock speakers are shot. I have a sony xplod 4 channel 50 watt rms (per channel) amp that I want to use with them. I know coaxials are better in the back but it is what it is and I am stuck with components. I need help with the following:

1. Which component set to place in the front and which in the back
2. Do I use new thicker speaker wire or are factory wires ok?
3. Most important of all where do I place my front tweeters and where do I place the rear ones? This is becoming a headache
4. If coaxials are absolutely better in the rear is there a way to DIY components into coaxials? If not please help me with question 3 or tell me where to go from here.
5. I have HPF and LPF settings on my amp for front and rear channels. How do I adjust those for front and rear?

I would really appreciate the help since I am doing a car audio install for the first time and dont really have money to spend on a professional install. A poor noob needing ur help

Welcome JojoGutts. I would install the 6500s in the front and 6000s in the deck. The front tweeter can be mounted in what is known as the "sail". It is that corner area that covers the bolts for the side mirrors. On the rear, you can mount them right next to the grille of the 6.5s. I assume you got them with the whole kit and kaboodle, so there have to be mounting cups to mount them on the surface. Or you can use the flush mount cups, but you would have to use a hole saw and that is a little more difficult. Those sets come with crossovers so there is really no need to mess with the amp's crossovers. Only thing you will tune is the GAIN knob on the amp. When all is connected, you turn the gain full counterclockwise. Turn on radio to about 75% of it's volume. Now turn GAIN clockwise until the speakers distort a bit, then dial it back a little. You are done. Any more Qs, we are here.

Thank you so much. This helps for me to get started. I am sure I will run into a lot of unseen problems since its my first build. I will keep posting here for advice.

I cant figure out the JBL 600c diagrams. The diagrams are a little different from my speakers. Which inputs on the speaker are for the amp and which for the tweeter? It has 4 male terminals sticking out on the speaker.

Connect the tweeter positive to the speaker positive, tweeter negative to speaker negative. Then connect speaker positive to amp rear positive, then speaker negative to amp rear negative. Of course left rear speaker to left rear output etc. The tweeter has a built in crossover so do not worry about damaging it. You said you have the Stage 600c right? If yes then that is how you will wire them. Remember that all crossovers on the amp have to be OFF.

An inline crossover or a passive crossover protects the lows from going to the tweeter you still need to use the high pass filter on the amp.

Can you please explain more. I am a total noob so dont want to screw it up.

They filter the incoming signal so each component only see's the frequencies it was designed for. Using a high pass on the amp keeps the lower frequencies from going to the mid. 80hz is a good starting paint. Using no high pass will result in your mid seeing frequencies below the range you set it at.

I see your point, but at 50 watts rms I do not think it critical to block anything below 80 hertz. This particular set was designed to play 50-20,000 hertz, blocking higher will rob the user of some of the lower usable spectrum. More so in this build that will not have a sub setup. I know 6.5s do not hit loud lows, but why block what little there is.

Thanks both of you for being so helpful and taking out the time. I did some research on my own to better educate myself but i feel the more I learned the more confusing it got lol. I do not have a sub so I think I will need the components to do the lifting for the low frequencies too. One thing I read that was kind of confusing was that some people suggested not plugging in the rear tweeters at all and just operating with the woofer. Because rear speakers are for rear fill and not really for sound? However, the discussions seemed to be emphasizing the sound stage and clarity of instrumental play and direction that I would expect to matter more in generes like jazz or rock. I mostly listen to house music and think having rear tweeters for "club" like effect might be better (since apparently thats what rear speakers end up doing by "spoiling" the sound stage). I would love to hear both of your thoughts on that. Am I right to think that the sound stage thing is more genere related or does putting in rear tweeter make the sound absolutely deplorable? A lot of people made it sound that I would be wasting the money I spent on everything by putting in rears.

I would personally just use the front speakers. It is easier to wire and tune. But rears are meant more for passengers. They like a song that is playing, no need to crank radio to feed them the front only speaker setup. In retrospect, I never had sound issues using all four speakers. So if those users had problems, I would attribute it to installer error.

My two cents...

6500's up front.
6000's out back.
Make sure the speakers are mounted tight to the door with NO gaps. Use a "rubber like" gasket to mount the speaker to if you can.
If these speakers were/are new, the 6000's (Stage series) have the capacitor built into the speaker wires that came with the set, this wire is to be run to the tweeter.
I would run the crossovers full range on the amplifier. They are full range component speaker sets. Use an eq to compensate for any overbearing frequencies.
The front speakers (Club Series) should be slightly louder than the rear speakers if everything is set the same as they are 3ohm speakers and the rears are 4ohm speakers.

I do have a roll of speaker wiring (12 or 14 gauge). Consensus is to not use that?

12awg is too big for what you are doing... 14 is too but it will work. 16-18awg would be ideal for your power output of 50w x 4 for the door speakers. I am running 16awg and 14awg for my doors. Mid/tweeter. 100w x 4 but realistically 60w x 2 and 30w x 2ish.
