I am going to throw a T112 in the back and get rid of the stock 10" in the rear deck. I was going to patch an LOC to the line out for the sub. However, since I've read that the processor reduces the sub output at higher volumes, I figured I would tap into the rear door output instead as long as it's full range. That way I would have no reduction in volume and wouldn't have to constantly fiddle with the input level control for the new amp/sub every time I wanted to crank things up a bit. So wondering if anyone knows if the rear door outputs are HPF'd or not.

Thanks

Bose system? Catch the signal before it enters the bose amp, by tapping into the b41 harness, wires 23 & 24 (rear L), 25 & 26 (rear R). These will provide a pretty clean signal from your HU to your amp's RCA inputs.

 

Sounds good. Thanks

 

Yep. That's what I did. Your 10" free air woofer will keep working. No need to remove it.
I suppose you mean a Rockford Fosgate T1 12"? What kind of box are you going to put it in?

I am using a kicker amp and I bought the optional bass volume control and I'm glad I did. I listen to a lot of different kinds of music, and a good volume setting for rock will rattle the car and distort with reggae, and not be enough bass for older classic rock, etc.

 

Yep.

I'm actually going to damp the parcel deck and remove the 10. Primarily since the 10 will be drowned out by the 12 and the 12 will give much cleaner sound. I'll be custom making a sealed enclosure and amp rack. Should only take away about 8" to 9" of total room behind the seat. I'll place lighted fuse access at the passthrough as well. I should be able to use hurricane T nuts inside the box to mount help mount it to the framework behind the seat, so it should be nice and secure and keep resonation down to maintain efficency. I'll probably have to slice the underside of the spare tire cover so it bends at the front edge of the box. There should still be plenty of room to pull the spare out. I have a line level control **** that I'll use for the sub. I don't typically like the ones that come with the amps since they are not controlling input, but rather boosting at range (45Hz for the RF amps) which is not what I am after.

 

I had a suggestion at an audio place to remove the 10" and the hole will act like a port to let more bass through. Another place told me it is better to leave it sealed. I left mine in, and working. I figure there's probably some sound up to 500 or 800 hz or whatever coming out of it that the sub isn't going to replace.
I've tried listening with the rear seat armrest door open or closed and can't tell much difference.

You should post pictures!

My kicker has a bass boost dial that boosts at 40hz, but it also has a separate remote bass volume that is full range. I mounted the **** way under the dash by my right knee. Not visible unless you get on the floor.
