buju2003tt Posted June 20, 2010 Report Share Posted June 20, 2010 yeah people my question is how many D3100s i would need to feed these 2 audioq 3500d.1 amps and what amperage alternator would do the job. each amp puts out 4300 wrms at 14.4 volts any help would be greatly appreciated Link to comment Share on other sites More sharing options...
tomypg Posted June 20, 2010 Report Share Posted June 20, 2010 Get as many amps as you can from an alternator, go for two of them. Then get maybe 4 D3100's. 1988 Honda City E Big 3 in 1/0 Venom 6x9 Venom 6.5 Components Response 4x100 midz and highs amp Fusion NV 2500.1: STOLEN 2 x 12 inch fusion nv subs 10 inch 5 doller subs in my doors PM me if you want help with electrical Link to comment Share on other sites More sharing options...
EricR Posted June 20, 2010 Report Share Posted June 20, 2010 A single 300a alt and 3 d3100's should do the job. I would also do 3-4 runs of 1/0 i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?

skittlesRgood Posted June 20, 2010 Report Share Posted June 20, 2010 1st of all you wont see 4000w+, it just doesnt work like that. but 4 3100s + a good battery up front should be ok, assuming its a 1ohm load. a high amperage alt is always a good idea. If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

Playa Named Joe Posted June 20, 2010 Report Share Posted June 20, 2010 I say 2 300amp alts and 2 3100s. Be perfect. 1994 Pontiac Grand Prix build Link to comment Share on other sites More sharing options...
buju2003tt Posted June 20, 2010 Author Report Share Posted June 20, 2010 I say 2 300amp alts and 2 3100s. Be perfect. so what wattage will i see from one of these amps it says 4300 wrms at 14.4 volts???? Link to comment Share on other sites More sharing options...
EricR Posted June 20, 2010 Report Share Posted June 20, 2010 Like stated before, only way you would see 8,600 watts is if after impedance rise your ohm load is below 2 ohms (strapped) and your voltage was above 14.4. There are alot of factors that you have to put into the equation. i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?

skittlesRgood Posted June 20, 2010 Report Share Posted June 20, 2010 so what wattage will i see from one of these amps it says 4300 wrms at 14.4 volts???? 1. music is dynamic and every tone will change how much power the amp puts out. 2. voltage drop, unless you want four 300amp alts and the 4 batts you will see voltage drop, ie. you wont be at 14.4v 3. impedance rise, normal rise can be 2-3x rise. so your 1ohm load becomes 3ohms. but thats only under the best circumstance, a test tone. just an example, at 40hz you see 2.5ohm. but at 50hz you see 5ohm. so since music has many different tones... get the idea? dont get us wrong, these are not bad amps and you will see a lot of power out of them. car audio is just a LOT more complicated than "this amp does this power" or "this sub will be this loud". its like 2 + 2 = banana. (if that confuses you then you get the point) lol If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.
