2 amplifiers Desperate wiring needs. truly puzzled

[dustalicious]

right now i have a sony xplod Head Unit (HU) with xplod 6" x 9"s in the back running from The from the back of it and an xplod 1000w amp, and then I have 2 12 inch Cerwin Vegas running off the xplod amp. everything sounds pretty good but i think the subs should be hitting significantly harder. My overall goal is to have this thing functioning at the highest standard it can. here's what i have to work with:

in addition I have an MTX External Crossover RTX01A here's the specs:

One high and one low pass crossover point, continuously variable from 32Hz-400Hz

Two continuously adjustable output gain controls

High and low level inputs

12dB/octave slope

Signal to noise ratio >96dB and >.05% THD

Four gang potentiometers

DC to DC Power Supply

an audiovox rampage 150w amp sitting alll by its lonesome drilled into the back of the other back seat, here are the specs:

high performance 150 Watt, 2 Channel MOSFET Power Amplifier features a light-up LED power bar, high and low-level input capabilities, remote on/off switching, gold plated RCA line inputs and speaker terminals, plug-in automotive type fuses, and thermal & overload protected output stage. Compatible with common and floating ground stereos. Compact chassis can be mounted under dash, under seat, or in trunk. Maximum output power: 150 Watts (2 x 75 Watts). Compatible with 4-8 Ohm speakers.

and a Pac Lc-2 in-dash bass level control knob with y connector (it has 2 sets of female rca running off the back under the HU deck)

Product Description:

Converts the speaker levels of a factory or aftermarket radio to RCA (pre-amp level)

In-dash or under-dash mount control knob

Adjusts head unit output from 2-40 watts per channel

Cuts out low frequency noise below 20Hz

additional questions:

bridging the amps? bridging the subs? wiring the xplod 6x9's? will the cross over mess things up if i have one in the HU or the Amp or both?

What model is the amp?

What models are the subwoofers? Do they have single or dual voice coil?

here's what i did: sub out rca's from HU to crossover. HP rca's to 120 amp Lp rca's to 1000w amp.

i left the remote, ground and 12v wires that are wired to the 1000w alone and piggy backed remote, ground and 12v from the crossover and 120w amp

i get a strange sparking sound when i shut my amp off?

Da.mn

 

[implodein]

does the sparking sound come from subs or 6x9s or both? I'd bridge the amps but you might need some solder,duct tape, torch , 1/2" bolts, torque wrench adjustments, 30 pk of miller, gas masks, and of course zanex for the next morning!

i kknow how to work the zanex, infact i'm pretty good at it, but what about the rest of this stuff?
