Pictures of Sound Systems

[hyde]

^I was going to say Billforde, but from the Red lettering on plates, I don't think that's in NY.. But I am %100 sure that I have seen above pic before...

I wanted to the exact same thing, but not on the gate, but up at the corners, because rear sound ***** on KJ. I think it is the way they are placed, so down low!

Also we would have to fill up the tailgate trim with sound isolation to prevent rattles...

My stereo has RCA outs as well, does anyone know if I can continue using my own set up as it is (with factory amps) and run additional speakers (possibly rears) to the RCA outs and use them without additional amp? I assume not, since you can either use internal amp or external amp.. Not internal for RCAs while using external for Harness connection?

First of all,
Gris: You can't just take the signal from the rear speakers to act as a pre-amp input to the another amplifier. If you've got an aftermarket headunit with pre-amp outs then just go and buy a car stereo RCA cable that is long enough to reach from behind the headunit to the rear gate. Then all you'll have to do is run a fused power line from the battery, not some other 12v wire, back to the amp. Just make sure you put the RCA cable and the power lead on opposite sides of your Liberty to avoid noise interference from the power lead.

hyedipin: You are correct in thinking that you can either use the amp in your headunit to power the factory door speakers or get an external amp to power the speakers. You can, however continue using the headunits amp to power the factory speakers and add an extra set of speakers with an extra external amp but you have to use the same set up I described above for Gris. To have an extra set of speakers you have to have an extra amp.

Hope that helps!

Thanks for your suggestion and valuable input, and welcome to the site, I am sure you will have a lot of info to share with some of us car-electronics newbies.

I have a question: I have subwoofer preamp outputs, I have two, and I am not sure why there has to be two of these outputs? Even if I get two sub boxes, don't they normally use same ouput?

My KDC-X590 has Subwoofer Preamp Output:The KDC-X590 is equipped with a pair of subwoofer preamp outputs. The subwoofer outputs can easily be turned on/off. When the subwoofer output is turned on, you can adjust the volume (-15 to +15 in increments of 2), set the low pass filter cutoff (50Hz, 60Hz, 80Hz, 100Hz, 120Hz, or Through), and the phase (normal, reverse).

Yeah, thats the same headunit that is in my Dad's Liberty. I've got to run to a class here (1:50-2:50) but I'll get back to you with a response/explanation a little after 3:00.

Installed in my Liberty is the following, and all installed by me:

HU: Pioneer Premier DEH-P980BT with iPod adapter and both Sirius and XM Pioneer tuners.
Amp: Kicker KX700.5 (running in 3 ch mode 165 RMS x 165 RMS + 500 RMS)
Front: Focal 165V2S components
Rear: None, as it should be!
Sub: 12" TC-1000 in a 1.4 sealed.
Acc: PAC-Audio Steering Wheel remote interface for Pioneer

Now for the pics!

Sub and Amp in the back.

My next upgrade will be to replace my amp with a Hifonics Zeus 6006 for the components, which I will run active, a Hifonics Brutus BXi-1606D running 1600 watts RMS @ 1 Ohm for the sub, and a TC-Sounds TC-3000 15". I'm going to run the 15 sealed, and will be making a fiberglass enclosure to mold into the side of my Jeep, keeping as much space as possible. The Hifonics amps are small enough that I'll be able to put them under the rear seats.

One thing I did forget to mention. The doors are completely sealed & deadened now. There's approx 3 layers of Elemental Designs Sudio eDead sheet deadener on each front door on both the inside of the outer skin, and the inside. All holes are sealed, and the speakers are mounted to a 1/2" baffle of MDF. From the door to the mid-range speaker the layers are: door metal > 3 layers of eDead > ring of non-hardening modelling clay > MDF baffle > ring of non-hardening modelling clay > speaker. Overkill, but the doors sound like a tank when they close and the road noise is cut down considerably.

gramifications, no problem.

Kriszilla, welcome to the site, and I went "wow" after seeing every one of those pictures. You did a great job fabricating that sub level to the panel. And I never thought doors would be able to hold the speakers there, with constant opening and closing.. You must have mounted them pretty strong. I was going to get the similar Pioneer HU, but was too expensive $500..

Hey there, Huseyin...

Thanks for the thanks. I did a lot of measuring before building the enclosure for the sub. Luckily, that model doesn't need that much airspace sealed so I was able to build it to the top and keep it compact.

As for the doors, the 6.5" mids are in the stock locations at the bottom, what you see at the sails are just the tweeters. They're only about 1.5" across, and only weigh a few ounces. The back of them are protected with a sheet of deadener.

If you're referring to the left and right (red and white) sub outputs as your two sub outputs, thats normal. Even though subs often act as a single speaker, rather than a pair, they still require a stereo input to the amplifier to produce sound. Check out the side of this amp from crutchfield:

The line in has a red and a white just like the back of your headunit. Hope that helps, if you have any other questions I'd be glad to help.

Bingo. However, if one is using a monoblock amp, they can use a 2-1 splitter to run both left & right outputs to the single input on the amp.

Thanks to both of you. I believe normally the L of the stereo acts as Mono. Or was it R. From what I have seen in the past, when there is a stereo output connection, L works as Mono if connected using a single RCA connection. From what I read at crutchfield, there is also not a huge difference between stereo and mono subs, since all it does is provide LFS.

What I loved is this new unit:

A bit pricey, but might be the right thing to put on a jeep, that is unless you plan to fold the seats individually, otherwise it totally defeats the purpose. Then would have to go with Kenwood SW1.

Thanks again on that sub connection info. One last question, how come I see that some subs have Front IN, Rear IN.. with two separate stereo RCA jacks, namely MTX Thunderlink or Basslink II.

Overkill, mainly. It just give you more options on getting a signal into the sub that it can use. Plus, say you run the rear RCA's to the sub, now you can use your fader to control the signal to the sub without changing the level of your front speakers. This is moot and unnecessary if the sub comes with a wired remote.

OK, Thanks for the info.

Let's keep the pictures coming.. (I think we had a very similar topic before, which might as well get merged into this one)
