How to hook up Subs?

I am a little unsure on how to hook my amp up. I have a completely stock system but i'm adding 2 10" W0s. should i use one of these?

I have a factory amp next to my battery that powers two 8" subs in the rear deck. Should I splice into the signal wires running to that with the above item?

It is NOT. Its Blaupunkt. My battery is in my trunk with a small amplifier for the 8s right next to it.

My aftermarket amp that im tryin got wire is a Precision Power PC2100

If you don't have any carpet or anything back there...its gonna rattle like a *****.

No do not touch the amp harness,your going to need to get some 4awg cable and a fuse holder.

LOL, i took all that stuff out. Its a 2009, you really think there isnt a carpeted trunk?

Obviously im not splicing into the amp harness for power. Just a signal. I have JL Audio 4 gauge wire for that which i will hook directly to the battery. Power and ground arent the issues here. Getting a proper signal to the amp is.

Depends how in depth you want to get.

A line out converter will work. If your run a Monoblock off the LOC, wire the positives on the LOC together and the negatives on the LOC together. Then T into either the left or right side and SOLDER them in. Cover with heatshrink then run your RCA from the LOC to the amp. For remote use the ACC wire from the factory amp. Again solder and heatshrink.

Ordered a converter since its obvious i will need one no matter what route i take. 15.99 from Best Buy.

If i wire each woofers coils in series with itself, than wire the two woofers in parralell to the amp, will that give me a 4 ohm load?
