i have been seeing some posts on here in regards to using the David Navone setup instead of the pricey Cleansweep and/or 3sixty. I am wanting to replace all of my speakers with the exception of the center channel with JL XR Evo's and run them with the JL 300/4 slash amp. I also am going to do a 12W6 and run that with the 500/1 slash amp. Please keep in mind that i am keeping my factory HU since i have navigation and LOVE it.

On the JL website, this set up is shown (http://mobile.jlaudio.com/pdfs/SYS_2.pdf), but they are running the main power, remotes, and inputs to the 500/1 and then just connecting that directly with the 300/4 and of course using an aftermarket headunit.

My question is why would i need to 2 adapters (NE-774V and NE-7V) for this setup, or would I???? i have seen KINGOFPAIN's thread and went to the website and thought this route would be a heck of alot cheaper, but am unsure of how to run everything. Also, if i left the center channel alone will that wonderful chick for my navigation still talk to me or will that be lost??

I know that there are alot of you stereo buffs on here that have already done this before, so i would rather ask now then mess up the TL............Thanks fellas and I welcome ANY AND ALL HELPFUL INFO!!

 

A few of us have used both the NE-774V and NE-7V because we LOCed the 4 main channels as well as center and subwoofer for a total of 6 channels. If your center channel will remain on your system but be powered by the stock amp, you only need 5 channels of amplification and 4 or 5 channels of LOC. The 500/1 can accept a high-level (speaker-level) input. So you could connect the wires going into the stock sub into the 500/1. The LOC would probably sound better but JL makes quality stuff, so who knows.

I have the exact same setup as you for amps (300/4 and 500/1), but I also have a small Boston GT22 for my center channel. I am using Navone LOCs now, but will be switching to a 3sixty this weekend because I am getting a lot of HISS in my system (see this thread).

So you COULD survive with only the NE-774V, but I've never tested the 500/1 using a high-level input so I don't know how well it works...

You will still be able to hear the navi chick, but her voice might not be as loud as the other four speakers.

 

so if i decide to do the LOC off of the sub wires, i would have a set of RCA's from the sub to the 500/1 and RCA's from the 4 channel LOC to the 300/4, correct?? since i am not changing the center speaker channel, i should probably just get a single LOC for the subwoofer????

my next question is do i only need to run 1 power wire from the battery to the 500/1 and then just connect the 300/4 to that one or do i need to have a splitter to run power wire to both amps?

So over the weekend, i stopped at the local JL shop and they quoted me $3500 for all of the speakers, amps, wiring, and included in that was $950 for LABOR!!!! that is where you get killed if you don't do it yourself. what i am thinking of doing is doing the speakers and all wiring myself and having them do my box and amp set up as they have a pretty sick idea where they place the sub firing in to the car, but still leaving about 4 inches between the back seat and the box.

Do you have the 1 12" setup? if so, how does it sound???

In regards to your hissing, did you take the signal/wires AFTER the stock amp or before and just disconnect the wires totally from the amp???

sorry for so many questions, but i am really thinking that i can do this myself and save a ton of money.

 

Hey dude,

So yes, you can solder an RCA to the stock subwoofer wires and plug that straight into the 500/1. It will deal with the signal appropriately. But I would get at least an LOC as it will probably do the down-conversion better, but I honestly don't know as I've never tried it.

As for power, you can run one power wire from the battery, but get a proper splitter in order to bring power to the 500/1 and 300/4. The 500/1 requires a 50A fuse just for itself, I realized that this weekend when I kept blowing the 30 and 40A fuses I was giving it. The 300/4 requires a 40A fuse. I would use a fuseable splitter so you can put maybe one 80A fuse at the battery and then a 40A and a 50A in the fuseable splitter. I ran two 4gauge power wires from the battery. One runs my 500/1 and the other runs my 300/4 and a small Boston GT22 amp which powers my center channel.

I have a 1 x 10" setup. I'm using the Boston G510 which is a pretty crazy sub and I have tons of bass and I'm happy. I'm firing into the trunk and it sounds great.

Here's what my setup looked like before I swapped out the e4300 for a 500/1:



I took the signal wires AFTER the stock amp, but this weekend I added a Rockford 3sixty.1 to my system and now the hissing is gone and my system sounds INCREDIBLE.

I'm really happy with the way it has turned out. I'll be making a new thread with my setup when I finish with the trunk trim.

No worries for the questions, bring 'em on.

Rob

 

looks good bro. where did you buy your JL amps from? Dealer or online? thanks and look forward to your thread.
