Installing Subs

[Ell 10+ year member]

I currently have a 1999 Infiniti G20 and am trying to install subs into it. I was wondering if it is possible to do so with my stock Bose head unit that came with the car. If not I need to know if I need an adapter or whatnot so I can actually wire the amp to the HU. Any feedback would extremly helpful. Thankss

Does your car have rear speakers? i know nothing about the make and model you have. And does ur amp have high inputs?

Also, my car already has an amp powering my stock front/rear Bose speakers which runs to the HU. I can get the power wire from the sub's amp hooked up it's just that I don't know if it's possible to get the remote and input wires connected to this HU with the stock amp also connected to it.

is the amp stock that is powering the front/ rear speakers?

Yeah the amp is stock

i would run everything off the amp that is in it already well except the power wires. they should be ran to the battery and be grounded on its own. the power running to the stock amp is prolly to small for 2 amps to be hooked to. im not sure how the stock amp's wiring setup is, but if the amp is ran with RCA's to the stock HU then i would just get Y intercept cables to run from there to ur sub amp. the stock amp prolly has its own remote, cant explain to you what color or anything like that, but there should be one and you could run that to ur sub amp.

So you think I should hook all the cables except the power cables to the stock amp that powers the front/rear speakers?

yeah that is the way i would do it, the only downfall of having the wires ran to the stock amp is the sound will be highs and some lows. your amp will beable to block some of that setting the sub amp's low filter right and shutting off the high filters and what not. the remote will be fine so dont worry about that there is no downfall to that. there is prolly better ways of doing this, but this is the only way i could think of doing it.

You think just getting a new HU would be simplier??

i have a 1993 g20

but it never had the stock hu while ive owned it, so i guess i cant be of much help

i would say get a new hu, its a much better idea

Before I changed out my HU I had the Delco Bose system in my car.

The first thing I added was just a sub and amp. I used the high level inputs to the amp. I ran the L/R rear speaker outputs to the input of the amp.

I ran new power from batt. to amp and the ground of the amp to the frame. I tied the remote turn on wire to the power wire on one of the Bose amps in the rear.

Then when one of the rear Bose units took a dump I took out both of the rear Bose amp/speaker units and put in 6x9's in their locations and hooked up another amp to power just the rear 6x9's.

Bose is so much fun... NOT!

angryeric116 did your car already have a stock amp powering the front/rear speakers though?

What I want to know is that even with a new HU will I still need an adaptor or anything so I am able to hook up the stock amp for the front/rear speakers with also my amp for the subs, or will it be able to hook right up??
