Full Audio System NO Line Out Converter

I took the jump this weekend and had my local installer finish my system.

I have a 2014 Overland (Alpine System).

I started a few months ago with a set of Focal 165 V30's in the front doors. They did the job but didn't sing as much as I knew they would with an amp.

On Sunday I met with my installer and had predetermined that I would add a JL Audio HD 900/5. I told him that I want to put Focal Access 165AC Coaxial speakers in the rear doors and add my JL W6 which was in my previous car.

We started talking about LC7's, 6's and 8's. My guy told me that with the JL amp, we could skip the line out converter as the amp basically has one built in. He said the LC's are all crap and to avoid them if you can. I'm going to talk to him today about the whole process but the jist of it is. The whole system is in (including a JL w6 that is in a stand alone box, until I decide to go to a stealth box) and it works. I haven't found any bugs yet other than a very very very faint white noise sound when the volume is all the way down (must be do to grounds).

Has anyone else heard about this option? Any drawbacks I should be looking for?

Greetings,

Out of curiosity, how come you did not get the Alpine system and the 8.4 screen in the Overland?

Also, what setting do you have the input voltage set on the JL 900/5? That could be causing the white noise.


Best for now.

Re: Full Audio System NO Line Out Converter

The Overland did come with the "Alpine" speakers and the 8.4. They both come standard on the Overland. I still have the 8.4 just got rid of everything that is Alpine. It made a huuuuuuge difference in sound quality and volume level. The new system sounds good from volume 10-20 when it gets really loud! The old system only sounded ok up at 30!

I do not know on the input voltage setting but I can look into it! Thanks for the advice

Re: Full Audio System NO Line Out Converter

Greetings,

Any improvement to the Alpine system will sound better.

The next improvement will be to upgrade the radio when the aftermarket's are ready. ADS has the iDatalink Mastero out, but they are working on a full feature set for the 8.4. Seek out fellow member 12V GUY for updates, he might even write first. Kenwood Execlon would be the best choice when they have the large screen format. Otherwise, Alpine would be the next choice when the 8 or 9 inch screen gets the port for the Mastero.

iDatalink - Maestro - Home

Best for now.

Re: Full Audio System NO Line Out Converter

I had no choice but to use a LOC in my Ram. It's true, that lot of amps have it built in. Mine does also, and it did a great job even with the OE-amplified signal. However, I needed to sum 6 signals in order to obtain a full-range output. Thus, I needed the AudioControl LC6i at minimum. It works great for me. I have 0 noise associated with it. True, some LOCs are crap. I have not read many complaints on AudioControl equipment. If you had the OE Alpine setup, you would have had to do the same, or buy DSP. You are lucky. I wish I didn't have the Alpine systems.

Great choice in amp.

Re: Full Audio System NO Line Out Converter

Talked to my guy today and he told me that he has the JL Audio 900/5 running directly off of the factory amp. He soldered on RCA cables on the factory amp and ran those to the JL. I'm sure it is more involved than that, but it works and sounds great! Looks like the way to go if you don't want a line out converter.

Greetings,

As long as it sounds great to you is what really matters.

You realize by going this route, you are stuck with DSP settings from the factory amp. The crossover settings coming off the factory system is your base. The original 6x9 is set to a lower sequence to compensate for the sub woofer. The focal 6.5 woofer is set around the bottom frequency of 55 hz (cycles), which means you are getting the bass frequency in the setting of the Alpine. On the JL HD 900/5 I would lower the gain (could also be the white noise problem) a little for those channels to protect the woofer and tweeter. A spike could damage the woofer over a period of time. You can also play with the frequency settings to bring the woofer more into a mid bass/midrange driver get that punch. The tweeter is sound is improved regardless since your are using the passive crossovers.

Their are two schools of thoughts regarding LOC. However, in the JGC with the Alpine DSP 7.1 surround sound predetermined factory settings, many go with a clean signal. Thus, the need to sum the correct 6 channels from the front woofer, tweeter and sub woofer via quality LOC or high end aftermarket DSP unit. A fellow forum member, VOYAGERX, took time and look into the real problem of the Alpine. Here is an interesting read:

Factory Frequency Response

The other option you have to improve the system down the road is to remove the factory radio (see my earlier post) and do not use the Alpine as a surround system. Plug in direct from radio to the amp.

Best for now.

Re: Full Audio System NO Line Out Converter

Now we are just getting way over my head! Thanks for all the info. I'll looking into the posts you are suggesting. So the JL amp is able to read the signal off of the factory amp but it doesn't "re-work it" like a LC would? I had the crossovers installed that came with the Focals, but via your post it sounds like they are not necessarily doing anything unless I use a LC.

Do you think I need to go the LC6 route to get the best sound?

Thanks again for all your help.

Greetings,

That is correct that the JL amp is able to read the signal of the factory amp. To re-work the signal and to improve the sound a little more is done via the JL's internal crossover and that is for the 6.5 drivers. This will take out the low frequency and let your JL W6 play more of low end sound as it is intended for.

Question: What size speaker is your JL W6?

The Focal crossovers in fact has improved the high end (tweeters) sound a great deal. And with the JL amp powering it, you are getting that clean and precise sound.

Do you think you need a LC6 or some other LOC to get best sound? The answer is simple. If your current set up is to your liking and it sounds great to you is what really matters. So the answer in this case is no.

If you decide down the road to install the stealth box, then my recommendation is to look into to an LOC or a DSP that reads the signal coming from the factory amp. Or, by that time you are ready, hopefully, an aftermarket radio will be on the shelf to purchase. The reason is, the Stealthbox is not cheap. Therefore, to really take advantage of it and to produce the low end sound as it is designed for, then it does did the right signal. You already have one of the best amps to power it. So, the answer in this case is yes.

That is why their is 2 schools of system design to correct our Alpine system. The correct design in the JGC should be based on whether you want to have a surround sound system like some of the European Cars or the Grand Cherokee Overland Summit/SRT models with the LOGIC 7 or a traditional front, rear and sub system.

Unfortunately, Chrysler produced a bad specification for Alpine to work with. And your simple upgrade is good for you, then, your objective is done. Sound is perceive differently by individuals and each individual might have different level. My level is audiophile.


Best for now.

Greetings,

Our fellow member ABARBS30 did indeed go with Focal's. For the front door they went with very nice component, 165 V30's. The rear with the Access 165 AC coaxial which does a nice job for rear fill.

Best for now.

If they have the JL Amp running off the output from your crappy OE Alpine amp, your speakers are not seeing a full-range signal. It would sound tons better if they sum the signals via DSP or high-end LOC. All the filtering is done at the OE amp, and there's no way around it. All they are doing, is boosting the crappy OE signal even more. It's not allowing near the potential of your gear. If you are happy though, that's all that matters.
