hey ppl i wanted to know if anyone has done this, installing a high and low rca converter to the existing wires of the oem sub instead of installer one of thos adapters in the back of the oem radio to be able to plug in an amp and after market subs?

thanks for helping

 

My JL audio Amp has one built in so I used the sub speaker wires for signal

 

thanks i got my answer right there, but is the remote wire there also?

 

If by remote, you mean remote turn on for the amp, no you will have to tap it from the OEM amp located in the trunk, I belive.

I did exactly what you were referring to on my old CL-S, and it worked perfectly for aftermarket sub/amp combo.

 

You can use a LOC if your amp doesn't have speaker level inputs. I have all 6 channel running off LCOs. Also, for remote turn on, you can't use the remote line off the OEM factory amp. The signal voltage is too low for aftermarket amps. It's like 7volts of something silly like that. You need 12v. I tapped into the fusebox at fuse #32. Use the lower part of the fuse connection so that your remote turn on is still protected by the fuse.

 

I am using LOCs by Navone, the NE-774V (4 channel) and the NE-7V (2 channel). Great sound for the price, $55 for both. Good low cost alternative to the 3sixty.

is there some kind of diagram i can follow?

 

is the oem sub connected to the amp in the right panel passenger side? can i just unhook the sub, becus i dont wanna upgrade ths speakers for now, i just wanna add 1 sub and an amp?

 

can anyone guide me here

 

here is my next question, is im only installing an aftermarket amp 2/1 CH, do i need to disconnect any wires from the front passenger oem amp from the sub or can i leave them right in there?i dont feel like blowing anything so i hope someone can answer me correctly on this

thanks

 

I guess there are 2 ways to do this.

1. You can find the wires for the sub at the stock amp. Cut and splice in new wires going to the trunk and the LOCs. You can then run the wires from the LOCs to the new amp and sub

2. You can pull down the cover in the trunk to get to the stock sub from behind. Disconnect the wires from the stock sub and connect them to the LOCs. You can then run the wires from the LOCs to the new amp and sub.

I'll try to post the diagram when I get home or you can do a search.

Hope that helps

 

Here's a diagram of the OEM amp and wiring.

Socket A is output to the speakers
Socket B is input from the head unit

 

I've been trying to find out if the wires from the head unit to the stock amp are lowvoltge, already. Why would I need to use the LOC. Couldn't I just soler in an RCA plug, then rout that to the new amp? I would think that this is low voltage, sice it is before the stock amp.

 

You can, but the signal is very low. Like 1v or less. NOT a good level. You're gonna have to use some serious gain on your amps, and that's gonna induse noise in the form of hiss. Some here have tried it and come away with very bad results. Those that do take the signal before the amp, usually use a line driver to boost the signal up to a 4-9v range. You can go either way. A good LOC for 30 bucks or so (50 for all six channels), or a line driver for 100 or more. Course, it really depends on what you want. Do you want to defeat the stock equalization? Add your own equalization? Adjust time alignment. I mean, if you're gonna go all out, a 3ixty can do all this for you, but a 6 channel 3sixty.2 is gonna cost you 400-600 bucks. How serious do you wanna get? The LOC is the quickest and cheapest way to get an aftermarket system into your TL and keep everything working like factory.

 

Thanks, Wyzard
For now, I'm just adding a 12" sub and amp and will use the LOC. Hope it doesn't drown out the rest. I have an old Titanium 4ch amp, and will add another later. I'm just not ready to do the whole speaker replacement, now and I can't imagine using the stock speakers with this amp.

 

what kind of line driver are you talking about, can you show me one? Id like to install that LOC but its too much work and too much time and i need my car everyday and cant drive around with such mess in my car, surely not if i have clients to go meet up, hope you understand my issue, thats why its gotta be quick,easy install

thanks for your help

 

Can i simply unplug my stock sub wires, hook-up the high/low converter to them and connect the aftermarket amp and my new 12" sub?

 

yeah, that is one of the easiest ways. TO just clarify, tkae wires from stock sub, connect to LC the nroute to new AMP. from amp to sub.

 

i just tapped into the wire right by the sub with the LOC, hooked it up to a ppi amp set on the low side for gain and what not, and i can still use the nav control to adjust sound output from the sub

 

thats great to hear guys, so you didnt have to unhook anything from the oem passenger amp right? any pics of the process?
