Hello all,

I am wondering if I would loose sound from my 2 10" subs at 4ohms each wired to 2 ohms, if i wired 2 more in and wire 2 X 2 in series and the 2 pair in parallel. I guess this would take me back to a 4 ohm load on the amp and would losee some boom. I am running a RF Amp pushing 377RMS and the subs are 10" Pioneer's. Any Ideas on how to get these to maintain a 2 ohm load or should I just break down for another amp? Dang what way to go.

Thanks for any info in advance.

Get a bigger amp. By the sounds of things you will need a different wiring method for 4 subs. If you are going on the 4 sub path, make sure all of the subs are the same.

The Pioneer subs are the new ones with the Carbinfiber cones ??TW-255-VC?? Single voice coil. But the way I am thinking is I will have a 4ohm load and not the 2ohm load for the full 377rms

Amp is a Rockford 351M Mono amp

Thanks again

To wire (4) 4ohm SVC's together to a mono amp for a 4ohm total load, you would need to wire like this...

Thank you very much for this info. Now will sound get better or will it get worst. If amp is stable at 2Ohm load with the 2 subs wont it cut out some of the Pound at a 4 ohm load. Sorry things I need to ask before doing this.

What model amp and sub do you have? If your amp puts out the same amount of power at either 2 or 4 ohms then it won’t matter which load it has on it, you will still get the same sound quality at either load. But if have 2 subs running at 375 watts @ 2 ohms then each sub is getting 187.5 watts each. Now if you add a total of 4 subs then each sub would be getting about 94 watts each. Now that’s assuming that your amp puts out the same amount of power at both 2 and 4 ohms. To help us figure out how to optimize your setup we need the exact model #'s of both your subs and amp.
