Re: 2014 Overland Audio Upgrade.

OK, here's the new list.

DSP: Rockford Fosgate 3sixty3.
Amps: 2 JL Slash 300/4v3 and 1 JL Slash 600/1v3
Sub: JL Stealth Box with 12W3v3-s Sub.

Speakers: ? Still not sure about speakers. Maybe Polk or Rockford Fosgate Power series. I may just use HAT imagine series speakers. My dilemma is the 3.5 dash and rear pillars. I want to retain the surround sound. Hence the 3sixty3. I'm leary of mixing brands.

For wiring I was going to intercept the RCA low level outputs from the factory head unit into the stock amp. Disconnecting them from the stock amp and running them into the 3sixty3 instead of using the high level outputs from the stock amp.

Am I on the right track now?

Re: 2014 Overland Audio Upgrade.

Greetings,

AMPS: The JL Audio Slash series is a CLASS AB amp that love to draw juice. I am not sure of the amps on 2014 Alternator you have. It might be a good idea to get some capacitors or better yet a reserve battery. The old rule of thumb, if you have the bass up and headlights start to dim really fast in your case, then you will know.

Speakers: IF you go for the HAT's, see if you can get a single L3v2 for the center. You be very happy with your front stage.

Did you check this diagram out?

http://www.wk2jeeps.com/audio/2014_w...io_diagram.pdf

You this as a guide. Make sure each speaker has an amp channel. You will have to sum the front door speakers in order to use the passive crossover. Otherwise, you will short one channel.

The train is almost their.

Best for now.

Re: 2014 Overland Audio Upgrade.

Summing won't be necessary. I'll be taking the output directly from the factory head unit that goes into the stock amp and re-routing it to the JL amps instead. From the main head unit it's just the 4 main speakers (according to the diagram). The factory amp is what splits into 2 separate channels with it's internal DSP. The original stock speaker wires may be replaced.

The setup will go.

3Sixty.3 -> JL Amp 1 -> Front doors and rear doors
-> JL Amp 2 -> Center Channel and rear pillars. (one left over)
-> JL Amp 3 -> JL Stealthbox sub.


I'll watch the current draw on each amp using a clamp amp meter on the input to each amp. It shouldn't be too much. I don't really crank the music up anyway.

Greetings,

The only problem I see by passing the OE DSP/AMP is you will lose the Euphony Surround Sound Steering Logic, which contains the matrix. If that is not important to you than the only thing you need to due is finalize your speaker purchases. Otherwise, if you want to retain the steering logic, then you have you might want to look into the Alpine PXA-H800 and the controller RUX-C800 instead of the RF 3.sixty.3 It is a 5.1 set up.

Keep us updated.


Best for now.

Re: 2014 Overland Audio Upgrade.

I see what you mean. The 3Sixty.3 cannot do 7.1 surround sound.
I don't mind replacing the 3Sixty.3 with the Alpine PXA-H800 but man they are really trying to squeeze every penny out of you though. You need the purchase the PXA-H800 and RUX-C800!? Yikes.

Re: 2014 Overland Audio Upgrade.

Greetings,

Yep.

If you can test ride a GC with the HK system or any of the fancy European Cars, listen to their system with the music you like on a CD or USB drive. See, if you really need the surround sound.

The way I did with both the JBL MS-8 and RF 3.sixty.3 is going to cost you more in DSP Units, interconnect cables because you want good ones and misc. install power cables.


Best for now.

Re: 2014 Overland Audio Upgrade.

OK, I've come close to narrowing the speaker selection down. I've looked through Rainbow, Audison, JL, HAT, and etc. At the moment I'm looking at Hertz speakers. Does anyone have any experience with them?

Also, I'm having a problem with the 3.5 speaker size. Is it possible to fit a 4 inch speaker in the rear pillars and the center dash? If I can then that opens up the selection dramatically.

Re: 2014 Overland Audio Upgrade.

Greetings,

The HAT L3SE went into the center and rear pillar. The speaker is almost a 3.7 inch. The center was no problem at all, depending what you get a 4 inch might fall in as well.

The rear pillar was tight and the speaker sits back a little from the grill. The advantage I have it is a wide band full range driver that is great for a point source application. The 4 inch would sit to far away and most likely throw off the frequency axis depending what you get. I have this speaker set up as band-pass crossover filter to eliminate the hi end.

In regards to speakers, look as DLS Audio from Sweden and Illusion Audio.

Best for now.

Re: 2014 Overland Audio Upgrade.

Why DLS and/or Illusion? Is there something wrong with Hertz/Audison? Also, how about a 3inch midrange in the center dash and rear pillar? Would it be too small? I'm getting confused. All these brands. Why one over the other?

Greetings,

DLS is know for 2 things: Sound Quality and options on mid range drivers.
I had them in my last setup in the Pathfinder and before that in my Xterra.

DLS - Start

Illusion is another company which is right up their with HAT. I choose HAT because of how they handle the off-axis frequency response.

Illusion Audio


Another option is to consider with Audison is the Prima line. I have not come across any good reviews on them yet. For what I hear, it is a line to watch out for. The nice thing about is they amps with built-in DSP Units so working out system is matched. If want to tap off the factory DSP to maintain the surround sound steering logic, these is another method to use.

Audison Prima

The problem in selecting speakers and recommending by others is that 2 people have different perception of how they hear sound. That is why I like to offer chooses that cover the music areas that you listen to. One of the problems when it comes to sound quality their are not enough places to listen to these speaker lines in the correct settings. The other factor which is very important, even through these all SQ speakers, they all have different ways of reproducing the sound in the critical area of the midrange and tweeter. On all of these speakers, including the one you posted, in the mid-bass, the high model, the better the punch, including at moderate volume levels.

The next level of speaker confusion exists between the brands is the use of the passive crossover or no passive crossover in the mid to upper models. What this means is where does the speaker company put their money into when designing. Creating the best dynamics of the driver or improving the crossover to help reproduce the sound. It could be even both. All of these factors have to meet the different budget points for the consumers. An all active crossover setup is going to be more money in terms of equipment, tuning and installation. If you have not checkout my writeup already, this is a perfect example of an all active system.

For example, with HAT, their drivers are designed to be played with an active (electronic xover) as the priority and the use of passive as secondary. Rainbow goes both ways and their are expensive. Audison is the same. Hertz could go both ways, but the little that I heard and what installers have said it is better on a combo of active & passive system.

So it really comes down to what type of driver you want for the proper application that meets your listening of sound. Since you indicated in the past you are going with a DSP, then match a speaker that allows to have full dynamic to take advantage of your equipment and what sound best to you.

In regards to a 3 inch midrange driver for the center and rear pillar is also an option. This is exactly what I did. In your case I would look for frequency ranges that give you the range of at least 200 to 16,000 Hz. This way with the DSP you can tailor it to your liking. I generally like the center to start above 350 hz so that you can hear the separation of the mid bass of the front channels. I do find that the center should cut off depending on the speaker around 8,500 to 12,000 hz in order to hear the separation of the hi's. In effect, you are making something close to a front 3-way system.

Best for now.

Re: 2014 Overland Audio Upgrade.

I've finally selected my components.

Hertz ML 700.3 x2
Hertz MLK 1650.3 x2
JL Audio XD - XD800/8v2 and XD600/1v2
Rockford Fosgate 3Sixty.3
JL Audio Stealthbox with 10W3v3-2 sub.

I'm not going to retain the factory steering logic but just go for an augmented 5.1 setup instead. The Hertz ML 700.3's will go into the center dash and rear pillars. The rear pillars will be tied with the rear door speakers in the DSP and have a X-over cutoff in the DSP at 250Hz @ 12Db adding as a rear filler. The Center 700.3 will be the center channel output at the same X-over setting. The Hertz MLK 1650.3's will be installed in the front and rear doors. I will get replacement pillar covers from the dealership that match the interior with the tweeter cutout from a HK system for the rear so I don't have to try and make something myself.

I'll use the passive crossovers the come with the MLK 1650.3's in addition to the DSP. I went back to the 3Sixty.3 because of something I noticed in the Alpine PXA-H800 manual. Even though you have an 8 channel output on the Alpine, 4 of those channels are dedicated to the front speakers. The Alpine makes the assumption that you are going to drive the front Mid's and High's independently. This would have been fine except for that I plan on using the passive crossovers as well. You would have to sum the front High and Low frequencies together before they are sent to the amp, wasting 2 channels. It also states that you cannot disable this function either while with the Rockford I can tell it exactly what I want the output to be. I can make all 8 outputs full range if I wanted to.
