Can I add a subwoofer to my existing factory CD6 unit? If so, how do I wire it? (I am sure there is no sub output on the head unit).

I have already replaced the factory speakers with aftermarket ones and that improved the sound.

I really don't want to replace the factory unit.

Thanks.

 

You can do it with a line converter.

 

I am in the same boat. I will keep coming for more details.

 

The problem is that the factory stereo doesnt have the pre-amps. and to power the sub your gonna need to run preamps to a amp, then to the sub. I had it done on my honda civc with the factory radio. (hate to admit i had a civic). Any way best of luck

 

Ok, my next question is what wires do I use with the line converter? Left speaker, right speaker, front or rear? and, do I need two subs, one hooked up to left and other hooked up to right?

I guess that was 2 questions.

 

Line-in converters can be easily added to a factory head unit. You will need to use both left and right inputs to get 2 pre-amp outputs. Front or rear, your choice. As long as there is a left and right signal. I used a line-in converter in the Ranger that I used to have, it worked just fine. Most models have left and right level adjusters so you can fine-tune the signal bieng sent to the amp. I am in the same situation. I also have the indash 6, and am looking to add a sub in the future. I am going to utilize a line-in converter to get the signal to a 5 channel amp. From there I will power the 4 5X7 Bazooka speakers that I have already installed, and a single sub. I am considering the Thunderforms custom-fit because I do not want to loose the seating space in the rear of my truck, and I don't personally need more than 1 10" sub to get the sound that I want. You can get alot of bass out of a single 10" with the right amp and wiring. My .02

 

Probably the cleanest way would be to use an external crossover, one that comes to mind is the MTX RTX 01, but there are many. With an ex. cross. you can use your speaker level (wires) for the input and output 2 or more (depends on crossover) to line level for your amps. This will give you tuning control of the crossover points as well as volume for each channel. Most of these type of crossovers can be had for under $100. Some amps do the same thing, I used some phoenix xs amps in the past that would use speaker level inputs and split them to separate channels.

Where do I get a line convertor for a 2002 F-150 Supercab V6. I have the factory HU, and a 6-disc CD changer that is behind the driver's seat under the rear single bench. I am wondering what a line convertor does? Will this make it easier and cleaner, where I don't have to rip out the dash. All I want to 2 do is get a small sub that will fit under the rear seat on the passenger's side, that will make my truck thump, but not rattle the truck apart. Any suggestions, please let me know.

 

I will be listening because I want to do the same.

 

Clarion makes what is called the "Camo Sub" (camoflage - spelling?). It is a self-contained 8-inch sub and 100 watt amp built into a sealed box enclosure. It can usually be ordered in a color that very closely matches your interior color. Mounting is on top of the transmission hump under the dash in the middle under the ash tray. For connections, you splice into the both rear speakers and connect them to the amp's high inputs. Only other connections are power and ground. This setup is what I have in my 2001 SCrew. You might think that an 8-inch sub can't do much, but this unit sounds very good for what it is. It adds a lot to the stock, factory system. See my gallery for pictures of what it looks like installed.

 

I haven't installed anything yet since I originally posted this question, but I am looking at the Kenwood KSC-WA62RC sub.

The Kenwood sounds similiar to the Clarion that SilvrDrgn mentioned in that it is already self contained, self powered, and has line speaker inputs to connect directly to the speakers.

 

Line-out converters can be purchased at Wal-Mart, Radio Shack, or just about anywhere that stereo equipment is sold. I got one from Wal-Mart, and it has 2 sets of RCA outputs (front and rear) it works great.
Hope this helps!

 

so using a 2 channel line convertor or one channel, just to get my sub thumpin. Are you guys saying that I can just tie in my line convertor from one of the two rear speakers from the positive and negative terminals of the speaker? Also how do I run a remote line to turn my sub off and on then?

 

It's best to get a 2 channel and hook up both rear speaker wires. Most amps when bridged use the signal from both stereo inputs. Using one channel will probably work, but your signal strength will most likely be weakened. That, and any stereo bass will only come through the sub from the one channel. Ex: If a bass guitar is only playing on one side it won't play through the sub if it's hooked up to the other side. Hope that makes sense
