Just want more bass for Bose

DR_ · 12-19-2012, 12:42 PM

So let me know if my plan would work okay. I want to keep it simple and just replace my bose woofers in the hatch with a box. I want to use a single 10" and a mono sub amp.
The amp and woofer would be under the hatch carpet with no spare tire.
I would use the existing bose woofer connections to go into the amp for speakers and turn on but would run a power wire and ground to something in the hatch.
I want to make it super easy to remove for track days.
I would prefer to fire the woofer down so that it wouldn't be visible but would consider firing up if it will make much difference.
I like this setup below and would maybe only change the woofer to face down and I would prefer the amp towards the front so I wouldn't have to lengthen the speaker level wires and turn on wire. Maybe add some handles to the side as well.
Does anyone offer boxes like this already or would I need to go local custom?

Why the preference for a downward-facing woofer? Just curious.

you would be better served using an LOC before your amp, rather than high level inputs. Audiocontrol makes some nice ones, and are quite reasonably priced. The LC2i can be had for about $80, and will put out up to 9.5 volts to your amp.

Even if you were to install the LOC using the subs inputs you would be better off.

Okay so I forgot that the amp is in the woofer so the wires that go to the sub are low level. So can RCA plugs be put on them and run them into the low level on an amp?

I prefer facing down so that I can keep it stealth. I suspect if facing up if there is any type of carpet over them that the carpet would be blown around.

It doesn't make much difference which way it's pointed, it still has to pump the same amount of air in/out the "back" as it does out/in the "front". It will bounce the carpet the same amount.

Mounting the driver "upside down" does allow you to use the magnet as a center support for the carpet. Just remember you have a huge magnet sitting there and don't set your laptop on it.

Exactly

NO you can not, you need a LOC to give you a clean flat signal to start with and to add what the bose system takes away in its processing.

I'm thinking of doing exactly this too, with a LOC, but is the amp for the Bose sub in the sub enclosure? Meaning the wiring to the sub enclosure is in fact low level? Please clarify bigaudio so I don't fry anything!
Thanks.

A lot of this info is in the AV section of the FSMs. The AV section of the FSM is a great resource for what you are doing.

According to AV, the Bose amp (behind and between the seats) sends an On signal to the woofer. That's says to me the the woofer has power (amp) that needs to be turned on, but I may be mistaken (didn't feel like digging any deeper when others probably know the answer already

).

Thanks I've read a lot of the audio threads but didn't think of that.

So I looked this up in the FSM and there is no amp in the sub. Only two wires from the Bose amp and confirmed in my car. (2012MY). I'm going to just tap the rear speaker leads for the LOC and from there to an amp and sub.

i would just use the sub signal from the bose amp with a AC LC2i, if you open it up there is a jumper you can switch that lets you use low level in, which will also let the LC2I correct the bass reponds.

Thanks 90 ST, are you referring to a jumper in the LC2I? If so that would be even easier.
Do the instructions point this out or is this obvious.

I'm looking into the same type of hook-up for my Bose/Navi system. Just looking to add a little more bass to the system. I'm looking into the Audiocontrol LC2i with a JL 10W3V3-2 sub, JL 500/1 amp and possibly a corner box like Wicked CAS has. I like the Zenclosure box, but don't want to give up my cargo cover.

Any thoughts on the corner style of box? I have something similiar in my 4Runner...
