If the wires can be tapped, would cutting them then putting more subs in without amps even be worthy? I dont blast them, I just like them to kick hard when I want them too, so maybe have an infinity without an amp and just re-route stock wire to them? (I have like, 0 knowledge with car audio, I mainly do stuff with live sound and such.)

I dont think the stock amp will have enough juice to power the aftermarket subwoofers...nor would it be any good for the subwoofers.

I unplugged the stock subwoofers as the aftermarket, than tape into them, the LOC sends signal to the amp, than to the subwoofers...

There are several options for which way you point the subwoofer(s) in your trunk, but the best way in most cases is firing toward the rear of the vehicle.

Sound travels in waves, and the deeper the frequency, the longer the wave. This is why tweeters are very directional, and lower range speakers (subwoofers) are not.

Another factor that comes into play is the fact that pointing the woofers to the rear of the trunk "loads" the woofers, which allows them to provide more output, similar to when a home subwoofer is placed in a corner. Any surface that you can bounce the bass off of usually makes it sound like it is louder, much like putting a tight bend in a water hose will increase the pressure.

Finally, reflecting the bass off of the rear of the trunk allows you to hear the bass further into the length of the wave, allowing you to hear a deeper portion of the bass from your position in the front of the car.


The only time that firing the woofers toward you would be recommended would be if you are building a 'wall of subs' behind you, or if you are putting subwoofers in a truck behind your seat.

• In a truck, not only is this usually your only option, but it also works very well because of the fact that the back of the seat loads the woofers giving you optimal bass for the small amount of cabin space that you have to work with.
• In the case of building a sub wall, the amount of bass you get will be determined solely on how much power you are using, how many woofers you are using, and the size of the individual enclosures. You will be able to hear the movement of the woofer cones, but you will have so much bass firing right at the back of your head that it won't really matter.

Thanks for the info, Much appreciated

I have a 12w6v2 also with an old school punch power 800a2 amp.I hooked it up a while ago and got the stupid error mess on the dash.

Did anyone figure out a real way to fix this?I think after 400watts the car is really picky to voltage draw.

Today is my day off so I might try a few things.I bought a huge capacitor and will run the sub at 8 ohms or what ever I can get out of it.I dont remember if its a dual 6ohm or d4ohm.

Any progress to share Mikey?

Hi tbal. Hey do you know where those clips are at? I cannot seem to locate them, thx

mikey33

Hi, I got the system installed and it sounds great! I got a little bit of rattling due to license plate and having interior still torn apart, but I think it will go away once it is put all back together. By no means am I an audio aficionado, but it definitely is an improvement over stock.

Roverron

Well almost there mikey get back together and enjoy.... LOL

mikey33

Woot! Thanks Roverron. Tbal, the clips you were talking about were the black one's from inside the trunk. I just used a rubber mallet and flat head screwdriver to get it out real easy

mikeevo

Would love to see that write up. even some tips and tricks. I am thinking about changing mine. I have 2 rockford 12s with a 900watt AMP. just sitting in the garage from my last car. would like to here the details and problems you had to overcome other than wiring. did you just tap you amp into the battery in the trunk.

mikey33

Hi. Well, I cannot answer anything regarding wiring because I had a shop do it for me, but how to get the sub out I can help if you want.

I do know they wired the amp to turn on with ignition and they did it through a wire in the harness going to the fuse box in the trunk. I am getting the red "battery light" now, so I might have to figure that out next. One thing after another.

Swapping out my Comand for NTG 2.5 comand made a hu, hu, HUGE in sound quality and bass response, and it uses the stock speakers...

tbal

Mikey sorry for the late response... I didn't even do that, unless the clips were loose from the previous owner or something, but i just lifted the cover from the corner and pried it up lol.

tbal

More info! Pix!?

AMGPilot

What sort of Pix's? It's a comand NTG 2.5 headunit out of a 2009+ E63, I've posted about the conversion in the past. You need to remove anything on the MOST ring that is NOT NTG 2.5 (In other words EVERYTHING that is in the car stock. Radio, Audio Gateway (Amp/tuner unit in the trunk) CTEL module, SDAR module (If installed) Lignuatronic module (If installed), CD Changer, Ipod Interface (If installed) Nav Processor/DVD Drive (If installed) Bluetooth Phone interface (If installed) You replace all that with NTG 2.5 headunit (which has Nav, Linguatronic, Bluetooth and DVD Changer built in), Main Amp, Sub Amp, SDAR/HD Radio module, Media Interface (Ipod interface) and a Conversion wiring harness from Comandonline.co.uk

Install took me 8 hours going very slowly, if I did it again I can probably do it in 4 hours

mikey33

I kind of forgot about adding pictures of the system installed!
Here they are though

mikeevo

Nice and Clean. , do you have any pics of where they spliced in or which wire they used for the 12volt signal switched. I am about half way thru the install of those rear lights as well , thanks for the Tip. I will post a DIY for it and save you from taking it apart again ,

And THIS is why I picked up an '09. Don't want to mess with the factory system if I can get good quality sound. That much of a difference eh?

Lycan

I like that....very nice.

mikey33

Hi Mike, I tried looking but everything is already sealed up so it would be very hard to get any pictures. I can't wait to see your DIY on the tail lights, it should help a lot of people out especially since it such a common thing to swap out.

Thanks

FWIW capacitors are usually just band-aids, if that. If you want to run a bigger amp, say like a mono sub amp pushing 1KW into 1ohm, you will likely need a second battery. You also need to ensure that your alternator is up to the task of supplying enough current.
