I was contemplating bridging my 2 subs together. I think at least, I am new to car audio and learning I guess. The plan I have is since the bridge connections for the amp are the far left negative and the far right positive just putting both of my speaker negatives and the pair of positives together in those connection areas. From what I am thinking this would give me more power than my amp does as is which is the 100x2 and also if it would be safe for my equipment.

Any input is still appreciated, but I have done a good amount of research and what I have come to see is that with my single voice coil subs the impedance is too low for my amp when bridged like that. At least from what I have learned, when bridging two single coil 4ohm subs (which have the only option to be wired parallel) the impadence is 2ohms which the min bridged impedance on my amp is 4ohms. Which I am guessing is bad
ok so your amp pushes 100 rms x2 @ 4ohm (155x 2 @ 2ohm) and 1x 300rms @ 4ohm if you wire both subs in a bridged parrellel form you are still pushing 300 rms so no you will not cause any damage... but if you run those subs on seperate channels you will be under powering the hell out of them...
yeah, but my min bridged impedance on the amp is 4ohms. and when wired in parallel my subs are at 2ohms. Correct? and from what I have read running below the min impedance is bad for my amp.
i shouldnt post when im tired... short answer no you cant push both subs with that amplifier... both subs require 250rms even if your amp was 2ohm stable you still need a minimum of 500rms to push both subs (600rms for life of the subs)
well they work, I have had this working for some time now. I have already made the decision of getting a 800w RMS monoblock amp to push them. From what I see you would do this and wire them in a series.
short answer apparently was to short.... wiring in parrelle you decrease the ohm resistance and thus increase the current draw of the speaker/amp, wiring is series you increase it thus decreasing the current draw of the speaker/amp... so if you wired to svc 4ohm speakers in series you are at 2ohm (which your amp is not stable of operating at) wiring svc 4ohm speakers in series you are at 8ohm which your amp will push but you are not getting as much power as you should and your going to be under powering your subs... so to lengthen up my short answer... if you wire in parellel your amp is pulling more current then it can handle @ 2ohm yes it will beat like a mofo till over heats, short circuits, or catches on fire... i tell you catching the carpet in your trunk on fire is no fun and the smell lingers forever yes you can run your subs off this amp... for a short amount of time with out causing any damage to the amplifier... at 8ohm but you are starving your subs of power if your @ 8ohm with your current wiring i would be surprised if you are hitting 50rms per channel and or 100wrms bridged at 8ohm's of resistance...
yeah I get what you are saying, I have already decided against that and will most likely be getting a single channel amp and wiring my subs to that. I looked at a diagram for wiring 2 svc subs to a single chan amp and it looks like the are wired in series, but wouldnt it make more sense to wire it parallel?
ok let me see here real quick ohm's law v=i*r (v\r=i) voltage = current * ohm's (resistance) 14.4= current * (in this case it is) 2 ohm current = 7.2 amp 14.4= current * 4ohm current = 3.6amp 14.4= current * 1 ohm current = 14.4amps 14.4= current * 0.5 ohm current= 28.8amps 14.4= current * 0.3 ohm ( i have never seen an amp that can push an ohm load past 0.3 ohm) current=48 amps i think that gives you a better idea of how and why most people choose to go to 2 ohm vs 4 ohm i my self prefer running subs @ 4 ohm because it sounds better the lower the resistance of the speakers the more power you can pull out of the amp... when an amp says stable @ 2ohm it means that the wiring inside can not handle the extra 7.2 amps of current draw for very long....
I get what your saying, but yeah I am most likely going to be getting a Massive Nanoblock N2 800w rms soon to power these svc subs. But if I wire them parallel would that make them 8ohm? so I should probably wire in series to get down to a 2ohm load.
