It can't be done unless you choose to include some power resistors in your circuit for impedance matching. The problem with that would be some of your power will be lost in the form of heat across the resistors without the benefit of contributing any sound.

Also, the amplifier's damping factor will be compromised, so you may notice a loss in sound clarity. It's possible that you might not easily tell with subwoofers, depending on the enclosures they're mounted in, and whether they're isolated in a trunk vs being in the same airspace with you (hatchback, SUV, or pickup truck).

What size amp needed with a sony explod player?

this bandpass enclosure is rated peak power at 1200 watts . what this means is that each subwoofer in the is peaked at 600watts to make 1200 watts . what your looking for is to power up the subs with rms continuous wattage . you need an amp that will put out 400 to 500 rms a channel to run this sub enclosure at 800 to 1000 watts rms to keep the speaker from blowing

I have two 12 inch rockford p1 punches powered by an 800 watt sony explode amp (2 Channel) and i want to install another 15 inch kicker with a 1200 watt amp not sure the model, i got it from a friend and...

I have a similar setup & I just run the second amp straight off the other amp by running positive & remote wires directly from 1 amps positive & remote inputs to the others amps inputs. But my head unit has RCA inputs, (sub in & front & rear inputs) so from my 4 channel amp I run 2 6 inch alpine S's to the front to the front RCA inputs of the head unit, & 2 Pioneer 440w 6x9 inch speakers to the rear inputs. & my 800w 12 inch sub from my 2 channel amp to the sub woofer inputs on the head unit. Has blown my eardrums for nearly 12 months now great stuff! Hope this has helped

I was given a kenwood kac742, what do i have to do to hook up 2 subs to it tom

You need:
1) 2 4-ohm subs
2) Appropriate enclosure
3) Amp wiring kit with RCA's

Connect each sub to a separate channel and set both mode switches to "MONO" (center position). In 2-channel mode, this amp is only rated at 80 Watts RMS, so you need relatively small and efficient subs. I'd say nothing bigger than 8" or perhaps 10". Rockford-Fosgate P1S48 (8") and R1S410 (10") will work OK with 50-150 watts RMS. Some others will also.

I have a rockford fosgate p250.2 amp hooked up to two 12' subs but the amp is not powering on... instead the protect light is on and im not sure if its because its so cold outside... please help and thank...

Remove the load from the amplifier (subs) and the RCAs
If the light stays on, there are internal problems with the amplifier, and it needs to be serviced.
If the amplifier works normally, attach the RCA's and power on again.
If it remains on, connect one sub, and then the other.
Your amplifier is a 2 channel amplifier rated at
60 Watt - 4 Ohm - 2 channel(s)
125 Watt - 2 Ohm - 2 channel(s)
250 Watt - 4 Ohm - 1 channel(s)
Your amplifier is not rated for a 2 ohm mono load.
If you have Single voicecoil subs wired in parallel, you have a 2 ohm mono load - your amplifier will eventually fail.

Protection light

You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.

Check your wiring, and if everything is fine you might have a blown or broken channel on your amp

Amp Will Not Stop Overheating

You say you have 2 p312d2 subs. Ok so the d2 stands for dual 2homs (2 X 2homs voice coils per sub) , conecting in parallel the 2 voice coils of only one sub will create 1hom load to the amp, and if your amp is 2homs stable per chanel that means you are lowering too much your homs causing the overhwating to it.
