Default Possibilities of adding another sub.

Well, right now I have a sub running off of my amp with 125watts RMS going to it. If I get another sub and add it on to the amp, how much more bass will I get? I would have two subs with 125 watts RMS going to them. I know where I can get another sub like the one I have for only $30 and the sub sounds good IMO. So, I think that it would be a good deal.

just wire it up in series. what ohms are the subs? the worst that will happen is that the amp will go to protech mode.

a better option is to get a more powerful amp

if you have 125W going to one sub, then adding another sub would mean 75W to each. thats pointless imo

i agree but double the cone area and the more sound u get. it may not sound good with the low amount of wattage but it would be easier to get a biger amp.

o and if u bridge them and then wire them to 2 ohms u get double the power.

No, I have a two channel amp. 125 watts RMS x 2. Both subs would be getting 125 watts RMS.

but if you bridge the t channels you will got more out of the amp

the subs might not have that high of rms and max.

So, if I wire them in bridged (together) I would be getting more power than I would if I were to just have them go to the seperate channels? Bridged the amp is 380 watts RMS. Would both subs be getting 140 watts RMS if I put them in bridged?

Do you have a 300w RMS sub? Do the Peaks match the sub and amp decently? If so, adding another sub, will just make it sound worse. Subs need a minimum amount of wattage to pump their big asses. It'* like putting a 50hp engine in a car that needs 300hp. Yeah, it'll move, but it won't be fast [good sounding in this case]. If you need more bass, I vote ditching the 300w amp, grabbing a 500w unit, and getting two 250s. If you get two subs, get two matching subs. You don't want a Wal-Mart brand sub with a high-end Pioneer. One will sound good, and one will suck. Not to mention if you get one that is rated for 250 and one for 300 RMS, that could be bad.

Not sure about the bridged stuff though.

Apparently I didn't explain it well enough. So, I'll just tell you guys what my equipment is.

Subs: I have one(but can get another for $30 from a friend) Volfenhag 12", 500watts RMS 1000 peak. Dual 4ohm voice coils.

Amp. Pioneer 760watt, 125 watts RMS x2 @4 ohms, 380 watts RMS x1 (bridged) @4 ohms.

Currently, I have one of those subs wired in bridged. It is getting 380 watts RMS. I tested yesterday to see how it would sound with 125 watts RMS going to it and it sounds pretty much the same, maybe a little less bass. What I would like to do is get another one of these subs and put it on the other channel, both subs would be getting 125 watts RMS. I was wondering if I would be getting more performance from that, or from just one sub getting the 380watts RMS.

Now that you guys have brought it up, what if I were to wire both subs in bridged together? How much power would be getting to both of the subs? One of my buddies has the same exact sub I have and would give it to me for $30. I will probably just buy it, if it doesn't sound as good, I will save up for another amp.
