Yeah sorry I typod 2 instead of 4...2 D4 can be ran as that diagram shows to 1 Ohm....and it is 1 D2 sub that can be brought to 1 Ohm....

My typing sucks.

Quick question. So I hooked everything up and sounds nice. Since my amp is 900rms and my subs are 800rms I set the gain to about 50% and push the subs pretty loud. I would like to push them more but worry about blowing them. what would be a safe setting on my amp to push them harder?

Yeah, you can turn it up, but as soon as you hear distortion, back off!! When I competed in car audio, I would over power my speakers all the time. Doesn't hurt if you make sure you don't have distortion!

Tuning Your Subs

If your amp is MONO do not " bridge " it . It has four post but it knocks it down inside the amp so you'll have ++ -- but it's actually + - inside the amp. They just do this to make it easier to wire your subs in on the outside so you can use a good sized speaker wire from your sub to your amp, usually about 10 gauge.

Here's the Specs
# Kenwood KAC-9105D Class D 1800 Watts Max
# CEA-Compliant Amplifier
# 500 watts x 1 at 4ohms
# 900 watts x 1 at 2 ohms
# 1200 watts x 1 at 1ohms
# 1800 watts x 1 Max Power Output
# 1 Ohm Stable
# Fully Digital Power Supply
# Built-In High Pass and Low Pass Filters
# You can link multiple KAC-9105D amps together
# Short circuit, DC offset, overload, and thermal protection circuitry
# Tuned Bass EQ (0-18 dB @ 40 HZ)
# Adjustable Phase Control: 0 or 180 degrees)
# Built In Cooling Fan
# MOSFET Power Supply
# Speaker Level Input
# Signal Sensing Auto Turn On
# Frequency response: 10-200 Hz
# All terminals are mounted on one side for easy installation
# Aluminum die cast heat sink
# Input Sensitivity: 0.2 - 5 volts
# Gold-plated RCA level inputs
# Gold-plated screw terminals
# LED Power-On Indicator
# Preamp RCA output
# Signal Sensing Auto Turn-On
# 4 Gauge Power and Ground Inputs
# Dimensions: 13 3/4" x 2 5/16" x 9 3/8"

It doesn't specify on the Voltage you'll need to get these results meaning if your battery is at 14.1 Volts or lower, which if you're using your factory battery and alternator you're more than likely going to be in the 13's so you're probably not pushing the full 900 out of it @ 2 ohms and @1 ohm it states 1200 watts. Them subs will take quite a bit of power as long as your box is the right size, and you're not sending a completely clipped signal to them. I've had these same subs for over a year now and i'm pushing 600 rms to them with no problem at all.
