412 CVX Posted September 12, 2011 Report Share Posted September 12, 2011 your amps should, in theory, be seeing two ohms. however, due to circumstances stated above, the amps probably won't be seeing two ohms. which means the subs probably will not be seeing 900+ watts. now provided your amps are tuned correctly and you have the proper electrical support, i'd say the subs will be seeing somewhere in the ballpark of 600 watts per sub. it may not seem like much, but it's all relative. you can't "hear" how many watts your system is pushing, you can only hear how loud it is. in other words, the number of watts your system has is somewhat irrelevant, although more watts usually = louder. people don't want drills and drill bits, they just want holes in their wall... if that makes any sense. hope that helps.

MrSkippyJ Posted September 12, 2011 Report Share Posted September 12, 2011 Are you asking a technical question about impedance or just making sure you have your system wired up for maximum output from your amps?

skittlesRgood Posted September 12, 2011 Report Share Posted September 12, 2011 They are putting out 750 way to pull a number out of your ass. in reality, no theyre not seeing 900 watts due to voltage drop and imp rise. only half of this statement is correct. you are correct about voltage drop, but since music is dynamic impedence rise isn't really a factor. impedance rise is still, very much, a factor with music. Are you asking a technical question about impedance or just making sure you have your system wired up for maximum output from your amps? very good question.

Mr.JaunDurfle Posted September 12, 2011 Author Report Share Posted September 12, 2011 I'm just making sure the system is wired correctly. Thanks to everyone for the help. I think I understand what you guys are saying. So I could put a more powerful amp on those subs if I only listen to music and wouldn't really have to worry about blowing them if the amp is tuned right. Man when you start getting all technical, I had no idea about ohm changes in music. Good inf, thanks.

Bluliner Posted September 13, 2011 Report Share Posted September 13, 2011 So I have two Kicker zx750.1's running to two Boston Acoustics SPG555-2 subs. So one amp to one sub. The subs are single coil two ohm, the amps are rated for a two ohm setting. My question is are the subs seeing the 900 plus watts that the amps put out at two ohms? If they are receiving 750 instead of 900, would you even notice? No... Since you're asking it's probably safe to assume that you're not happy with something in your system and are thinking about changing amps. Am I right or are you just curious?

Mr.JaunDurfle Posted September 13, 2011 Author Report Share Posted September 13, 2011 It's not a question of 750 verus 900, it was mainly a question of if the amp was seeing a two ohm load. I haven't hooked the system up yet. I had one sub and one amp in my other truck to make sure there were on air leaks in my boxes and it sounded good and loud. But when I took it out and put my 10 inch sub and 500 watt amp back in, the 10 seemed to sound just as loud. So thats what got me thinking.

From what you described, the subs are/will be wired to the amps correctly and in the most efficient way possible. IIRC, you said the subs were SVC? in which case there isn't really any special wiring to be done. just match positive to positive and negative to negative and you're set. as far as a bigger amp goes, i probably wouldn't recommend it. I don't think i've ever seen a SVC sub able to handle more than 500 watts. if your current subs and amps get along nicely, then leave it. if you ever want more power in the future, you will want to upgrade both amps, subs, and more than likely your electrical support as well. just make sure your amps are tuned properly (search the forum for "clipping" if you don't know how) Quote Just say no to Ground Pounder Customs.

Mr.JaunDurfle Posted September 13, 2011 Author Report Share Posted September 13, 2011 Thanks 412 CVX. The subs are two ohm single voice coil and are rated from 100-1000 watts rms.
