I have read a lot about how to go about adding subs to the existing shaker 500 unit but I have heard mixed thoughts on using a line out converter. For one I have heard that it works perfect and some say they get a very weak bass sound... Also I have heard of different locations to pull it off of like the rear deck speakers or that you will get a cleaner signal off the door subs. Also I dont want an aftermarket HU & what is a good line out converter? Can someone please help me out! Thanks

Also if you were wondering what I'll be running...
2 Rockford Fosgate Punch 4 ohm 12" subs P3D412
& 1000 watt Rockford Fosgate amp @ 1 ohm P1000-1bd


Link to a good sub installation guide I found too

 

I fyou have the shaker 500 already then just use the line out that goes to the stock amp. You will have to figure out what wires to tap from the smaller connector with a wire diagram. You can tap in a small piece of wire to the right wires and connect a rca plug to them that you can get at circuit city.

 

oh btw. you wont need a line converter if you do it this way.

 

line out converter off of the rear speakers would work just fine. just know that if you fade all to front, you will lose your bass.

 

Use the JL CleanSweep ForTheWin hands down. Period. The best.
Wont be disappointed at all.

Yea, what he said.
Now what about the 5V turn on voltage of the shi**er 500 and aftermarket sub amps needing 12V turn on lead voltage. Got a fix for that one no one has covered. "
Its so simple".
No its not. Its called a Shi**er 500 for a reason.

 

Okay then what do I do about the 12V lead and can i use one of the cleansweep products only for subwoofers? I dont want to spend a ton of extra money and replace all my speakers right now so how do I go about just adding the subs and still get good bass response

 

for the 5v fix, find a switched 12v signal somehwere on your fusebox and run that to the remotes on the amps.... easiest solution i have used.... I have never really been a fan of line converters, nor do i think the outputs on the shaker 500 units actually seperate to true frequency range to run a sub properly.... too "BOOMY" is that makes any sense to you guys.... I know havin the multi cd deal is cool.... but that unit sucks.... I would stack up some bread and get a decent head unit and go from there.....

 

okay so if I decided to get a new headunit how would I connect the existing speakers then?? its not even a normal 4 speaker + subs setup since it has the door subs and everything...

 

Use a TO220 LM7805 voltage regulator to go from the 12V turn on voltage of
aftermarket head units to the 5V the shaker amps want as a turn on
voltage. There are adapters to get the low level needed to interface with
the shaker amps for the door subs. Been done many times before....

 

+1 on the regulator. As far as hooking up your speakers find a harness kit that goes to the car Metra part#70-5521, comes with the rca's to hook into the pre outs of the head unit.... easy to do. Get the install kit also Metra part#99-5812, its for a single din, double-din setup is part#95-5812. Hope this helps you out.
