Need Amp Advice - Gonna run a single RF HE2 12

[MPDano 10+ year member]

I need advice on powering this beast. I do not want to run multiple Amps, so I need a 4 Channel.

The Sub being a Dual Voice Coil can handle RMS 100-200 per Coil.

2 Channels for the Sub (DVC) and 2 Channels for the Fronts.

Any suggestions? Oh, budget is under $175. Used is ok too.

going to be hard since most 4 channel amps dont run lower then 4 ohm bridged and you are running a dual 4 ohm amp, might want to look for an old school amp that runs 1 ohm per channel

or get a 5 channel so u can run the sub out at 2 ohm

Great Amps linked. I had my eye on this one too:

Product: MB Quart DCS4125 4 channel amplifier

Specs:

Discus Series 4-Channel Class AB Car Amplifier

RMS Power Rating:

4 ohms: 125 watts x 4 chan.

2 ohms: 250 watts x 4 chan.

Bridged, 4 ohms: 500 watts x 2 chan.

I was thinking of running 2 or the 4 channels to the Woofer, then using the remaining 2 for the front speakers.

problem is you will only be able to power the sub at 8 ohm which will be only 125 watts to each coil with that mb quart, great amp, but u really need a single 4 ohm sub or dual 2 ohm sub for its full potential.

jump on that ppi

Whats the PPI? The Infinity? Also, I am confused since the MB Quart has 125 watts times 4. I am using 2 of the 4ohm 125 watts to the Subwoofer. I thought there are separate connectors on the Sub.

yes 2 connecters one for each voic coil. so you will only send 125 watts to each voice coil when that sub wants atleast 200. you will be underpowering it.

this is a ppi, better amp then the infinity easily. precision power.

It's rating is 100 to 200 per voice coil. 125 would not be underpowering it.
