Right now I have an amp and im looking to buy new subs. I want to parallel wire it to the subs. I want to wire it that way I can get the most power out of my amp. My amp can handle a 2 ohm load. But do the subs have to have an impedance of 2 ohms too....so they can handle the amp? Or can they be 4 ohms?

Also, the lower the ohms....the better/louder?

Thanks

2 4 ohm subs wired parrallel is a 2 ohm load. Lower the ohms=more power, only if your amp can handle a low ohm load. More power doesn't always mean louder/better.

Thanks.

Im looking to buy either 2 12's or 3 10's.....so if I were to buy 3 10's and wire them up in parallel....what would the ohm load be.....if all 3 subs were 4 ohms?

Three SVC 4 ohm subs will present a 1.33 ohm load. To get a 2 ohm load, your best bet is to either get two SVC 4 ohm subs or two DVC 2 ohm subs.

Don't like rockford subs? Then don't look at my car =)

Is your amp a D Class mono amp or a 2 channel amp? I ask because alot of people misunderstand the rating of an amp when it says it can handle 2 ohms. Most D class amps will handle 2 ohms with no problem at all, but most 2 channel amps will handle 2 ohm STEREO, or 4 ohm MONO. In most cases the amp would need to be a High Current 2 channel amp to be able to handle 2 ohms mono. Just my 2 cents...

Here are the specs.....

2 x 200 Watts RMS at 4 Ohms
2 x 400 Watts Max at 4 Ohms
1 x 800 Watts Max at 4 Ohms Bridged
2 x 375 Watts at 2 Ohms
Electronic Crossover Network
Bass Boost Circuit
Bridgeable at 4 Ohms
2 Ohm Stereo Stable
Tri-Mode Capable
Gold RCA Inputs
Line Outs For Left &Right Channels
Power &Protection LED Indicators
Soft Turn On/Off
Frequency Response:15 Hz-35 kHz
S/N Ratio:90 dB

So if I wire 2 12" subs in parallel....that would give me a 2 ohm mono load right? Im guessing "stereo" is easier for an amp to handle. Maybe this would explain why my amp would cut out when I wired my subs that I had in parallel.

There are odd impedance subs. I once had three MTX 10's at 12 ohms each, paralleled to 4 ohms. They weren't very good subs, but it did work.

JL audio has 6 ohm subs don't they? Three 6'ers in parallell makes 2 ohms.

Someone needs to go back and relearn thier algebra. It is 2 ohms.
