yea the rear sub is pretty much a joke. They do have 10 inch subs in the door. I threw a alpine type X in right now. (Kinda of over kill but im tired of my amp or sub blowing so i have a nice little combo. if I blow this, then i don't deserve a subwoofer ^_^ ). But yea i took my sub out legit a week after i got the car because it was pretty much a joke to have.

 

Are you using the stock HU? If not, are you doing high or low level inputs from the HU>Alpine?

 

I am using a very sad scorshe line out converter, however I am going to probably buy the MTX ReQ because the bass from the line out converter is less than stellar. Its loud as hell, but the tone is quite muffled and lost. Trying to change a headunit of the 2007 sedan is like trying to get world peace. Way to much trouble.

 

does anyone by chance know what the specs of the stock bose amp is? Nissan/Infiniti/Bose are of no help what so ever

 

I have tried figureing it out but I am just as lost as you. I would discourage against trying to fit in a sub in the exsiting hole. A few reasons, 1) its a free air sub, they do not preform even close to a boxed sub, 2) you need to find a free air sub that is close to the same specs as the bose sub, otherwise the amp will clip and you will ruin the bose amp 3) mounting the sub to fit will be a headache because the bose sub is not a standard sub, so mounting a new sub will not fit with the top cover, my friend already tried it. Just go the extra mile, get a MTX ReQ, box, amp, sub and have a much better, responsive and nicer tone sub to go with any music you have. PLuss the bose amp cuts the levels at louder noises so even if u put a nice sub in there, it would still sound like **** (aka, the reason why im getting the MTX Re-Q to restore the levels im currently missing)

 

Hey Zomorg, had a question regarding your response.

I am going to hook up an external sub and I have used LOC's in the past. I have a hard setup for the sub and amp so I am not too worried about any loss from the LOC.

What I am wondering if you can answer is this:

(1) How did you connect the LOC? Did you tap the sub wires int he back or somewhere on the door speakers?

(2) Do you HAVE to use an LOC? I don't see any other way to go about it, but someone else online posted something saying that no LOC was needed and to just tap into the line-level sub output from the bose amp to the bose powered sub. Is that possible or make any sense at all?

Any input is appreciated, thanks!

 

Hey well a little update, threw the schorshe loc out and currently running an audio source lci2 bass restorer and let me tell you, what a difference. To awnser your question I too the line running out of the amp to the sub connector, turned that from mono to stereo and then it was send through the restorer to the amp and so forth. You can possibly get around the loc by taking the input pre Bose amp, I got tired of trying to figure out how to keep that line though constantly at close to 2v input, and honestly the bass is pretty much tuned from that amp for that stock sub. Honestly I would go LOC to one protect your amp, and to give you a much much better sound. It is well worth every dollar especially if you are completely replacing everything
