tristan560 Posted January 6, 2010 Report Posted January 6, 2010 Okay so ive seen this here and there...people saying that running 4 subs to one amp will have much more rise than 1 amp per sub. Any real truth to this? <u>99 Jimmy SLT 4WD</u> Systemless. <u>99 Grand Prix GTP</u> DC XL 12 on 1.5k tuned lowwwwww.
Torres Posted January 6, 2010 Report Posted January 6, 2010 that's always what i've believed as well.
Rogers Posted January 6, 2010 Report Posted January 6, 2010 yes that is correct... if you ever get a chance to use a multi meter on multiple subs hooked together you will notice that the impedance is a little higher each time you add woofers.... say for instance... when i had my 4 type r's... they were dual 2's... if i hooked one of them up in a parallel circuit, the multimeter would read like .95ohms or so..... then i would series each one and parallel them all together and the multimeter would read like 1.6 or so... so just by having 4 of them hooked up at a 1ohm load, my impedance was rising to almost 2ohms... that that was just sitting out on my work bench with no box and no power... http://www.stevemeadedesigns.com/board/topic/79921-rogers-700-dream-car-update-page-17-a-wall/?p=2335774 93 Saturn SC2My system4 SA-15's Walled 2 Cerwin-Vega S2000's 3 Kinetik Hc2000's Dual 200amp alts. you guys done with the peepee touching contest or do I need to end it?

Thanks for this comment makes a lot of sense.
Rogers Posted January 6, 2010 Report Posted January 6, 2010 Thanks for this comment makes a lot of sense. no problem... just sharing my hands on experience...lol.. lets just say... i had the 4 of them hooked up to an aq2200d and they barely moved... im guessing with voltage drop and impedance rise i was getting somewhere in the neighborhood of 1400rms to them... plus they were new and very stiff... but it was loud as shit though http://www.stevemeadedesigns.com/board/topic/79921-rogers-700-dream-car-update-page-17-a-wall/?p=2335774 93 Saturn SC2My system4 SA-15's Walled 2 Cerwin-Vega S2000's 3 Kinetik Hc2000's Dual 200amp alts. you guys done with the peepee touching contest or do I need to end it?

Eric B Posted January 6, 2010 Report Posted January 6, 2010 It is said to have less impedance rise.. I will be testing this within a few months... Last year i tried testing but amps didnt like the low load... 2007 Chevy HHR LT UNDER CONSTRUCTION 1st Place Loud N Low 2010 MWSPL Finals 3rd Place Xtreme 3 2010 MWSPL Finals
Rogers Posted January 6, 2010 Report Posted January 6, 2010 thats DC resistance, not impedance.i havnt experimented with this yet but i do plan to some time... whenever i get around to it lol. very true, but the dc resistance is an example... and an easy way to see how impedance rise effects a load when adding resistors. fyi: impedance is a measure for the manner and degree a component resists the flow of electrical current if a given voltage is applied. anyways if someone knows for a fact that im wrong, please feel free to chime in... http://www.stevemeadedesigns.com/board/topic/79921-rogers-700-dream-car-update-page-17-a-wall/?p=2335774 93 Saturn SC2My system4 SA-15's Walled 2 Cerwin-Vega S2000's 3 Kinetik Hc2000's Dual 200amp alts. you guys done with the peepee touching contest or do I need to end it?
