Hi all CL members
I know this topic has been discussed before but maybe some members out there might do something extradinary.
Well, has anyone adds subwoofer and amp to their nakamichi system and keep the oem head unit?
I do know that in order to keep everything stock and add aftermarket sub and amp u must use the hi and lo adapter.
Does any member knows where do we supposed to connect the hi and lo connector to?
I think we supposed to connect it to the speaker wires but I'm not so sure wether front or rear speaker?
Do we splice the speaker wires or cut it off?
Any advice is greatly appreciated.

 

I would cut off the connection to the stock sub and spliced the Hi & Low adatper to the rear sub connection.

 

So you want to amplify an already amplified sub.?

 

You would want to tap into the oem subwoofer output in the trunk. Look up the term "LOC" and don't buy a cheap one

 

Exactly! Splice into the wires that use to connect to the sub in the rear. I learned my lesson, do not buy a cheap hi lo. I did for the first one I had and it had crazy feedback. Buy a good one so u don't have any issues with an annoying sound. Plus the quality will be better in the sound.

 

That's what my first though, I wrote this to ask for help just to make sure. Those sound guys wanna charge $120 for installation but I figure this would not be a hard task with such help from Club LExus members like u
Thank u so much for chime in

 

I wana add aftermarket sub and keep the oem head unit, by doing this we need Ana adapter calls hi and lo

 

Thank u very much for ur input.
Just one important question, which is the best way to splice into oem sub wires without damaging or possibly cutting those off? Or can we connect the hi lo rite into the positive negative terminals on the oem sub?

 

Thank u Sir..
Sonic electronix has few of them for less than $7 would those consider cheap hi lo?
A $20 hi lo is decent?
Thanks in advance

 

Once you figure this out you should do a DIY with your sub woofer set up and install.

 

I looked through a few on sonicelectronix and if I was to buy it would be the stinger sgn12. They have a sgn13 where you can adjust the input. But you can do all that on the amp so buying sgn12 for less is a better deal. PAC is a good company too. I used their loc on my last car with no noise issues. Just make sure to have a god ground.

Google "t tapping" so you don't have to do any cutting. Walmart, ace, homedepot or RadioShack should have some.

 

Yo biguppy man.. Thank u so much for this valuable info man..
This helps me a lot man.. Really appreciate it

I just looked at this video on YouTube after u told me about t-tapping, it's so easy to tap into oem speakers, I would of never knew about this until u told me bro. The SGN12 has excellent rating so ima get that. I will take on this project by myself with all the help from u. Thank u

**** one more question, several places selling t-tap connectors but it comes in different sizes. Do u know that gauge is the oem GS400 rear sub speaker wires?

 

NP. I think they are 16 from the look of it.

 

You would want to tap into the oem subwoofer output in the trunk.

 

Any updates on this ? Just wondering what set up you went with and how it sounds ?
