is it worth it to get another sub?

So if i have 2 subs in their own boxs wired to 1ohm each...is that a 2ohm load on my amp....ohms don't just add do they? it's how it's wired...the power is wired through both whole subs

Are you bridged, or running in stereo? If the two woofers are wired to one ohm, by paralleling the voice coils, that is 1 ohm per woofer. True. If you wire one woofer to each channel of the amp, that is 1 ohm per channel. True. If you wire those 1 ohm woofers in series, for 2 ohms, and then BRIDGE THE AMP, the amplifier is doing EXACTLY the same work, as running the amp in stereo mode to one 1-ohm woofer per channel. True. SAME power as running stereo at 1 ohm per channel. Whether they are in one box or not, ELECTRICALLY, they do not change. The impedance of the woofers remains the same. It is all in the wiring.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

So what would you do run them at 1000/2 @4ohm per channel 1500/2 @1ohm per channel 1500 bridged @2ohms...it's have to wire them series to get the 2ohm right.... I'm actually rewiring them right now and im pretty sure i'm just going to wire them to 1ohm each so that'll be 1 ohm per channel right. Sorry i've been so thickheaded, i just don't have a lot of money to be spending on subwoofers so i'm trying to MAKE SURE 100% that it's worth it...i guess i like to hear different people opinions thats why it came up a few time SORRY but you guys saved me couple hundred bucks! mike

Your impedance will be higher, so your amp CANNOT make the same amount of power. Ohm's Law, baby! Perhaps you should learn it, know it, LIVE it... Three 2-ohm DVC woofers, can be wired to 1 ohm each. Wire all three of THOSE in series, and you get 3 ohms. Connected to an amp in bridged mode, and your amplifier is "seeing" 1.5 ohms per channel. That is roughly a 33% decrease in available amplifier power. That is also the only safe mode, while still getting maximum available power. 1500w - 33% = 1000w 1000w / 3 woofers = 330 watts per woofer 330w is actually LESS than half of your current 750w 330w per woofer vs. 750w per woofer = ABOUT a 3dB loss per woofer 3dB + 3dB = 6dB loss from reference 6dB off reference + 1.5dB from a 50% diaphragm increase = 4.5dB loss from reference Those are solid numbers. Is that straight enough for you? You WILL be quieter - 4.5dB quieter! - maybe you'll hear it, maybe you wont - but it WILL be less output with three woofers than it is with two woofers, using the same amplifier. You HAVE to allow the same amount of power PER WOOFER if you expect it to be louder. That means you would have to connect an amplifier that can make 2200 watts, into the available 1.5 ohm load. THAT is JUST to be even detectably louder! You have to go to 3kW and 4 woofers to be SURE that you are DETECTABLY (to the human ear) louder! Dude! Can't argue with Ohm's Law... This is why EVERYBODY that has answered you has mentioned this! KP - no sweat, mang!

ALL i needed...thanks bro
