Subwoofer Help

[Novistion]

So my car got stolen (yay .-.) and because if me being 16 blah blah, my mom just got $10,000 from insurance (That car still worth $32,000 but whatever). And currently I am driving our old 2002 Kia Sedona. Anyway, something I miss from my Buick Enclave is the Bose stereo system and the sub I put in. I don't wanna rip out the audio stuff in the kia because it is about dead. (motor and rear axle problems haha)

 

 

Anyway here is were I need help. I am using a PA Amp (this one: http://amzn.to/1Ii9aAX) to power this: http://amzn.to/1LAuXTF PA but I have a Dual Sub (because I'm a bass head) but because there isn't any eq on this amp, it sounds bad and I know isn't good from the sub (this is the sub: http://amzn.to/1CTsGkH) I have the PA speaker on channel one, and I want to use that sub on channel two so can anyone help me just get the low frequencies to the second channel some how. A device or something. The input to the amp is from my droid turbo 3.5mm to a 1/4 adapter. I can always split it so I have different input to have something in between input and channel two. Someone please help. I know this isn't really the right place to get help but I'm desperate. Help.

Get a real car amp, they have a remote wire to control the amount of base, problem solved...

Like I said, I'm not getting into ripping out and putting wiring into it.. I am just looking from something to fix this.
