3 10's
 

what amp would be good for running 3 10" Infinity 1030W's?

Well, the 1040W's power range is 60 - 250 watts RMS, so if the 1030W's are similar or last years model, then you need to run an amp with at least 75% of that power (RMS), so a minimum of 180 watts going to each sub. Also are you going to run an amp for each sub? or are they 6 ohm subs to be wired in series to get a 2 ohm load? which would get the most power out of a single mono amp. Most amps are 2 ohm stable, it takes a little $$$$ to get a 1 ohm stable amp. If your subs are all 4 ohm subs and you try to wire them in series, you'll end up with a 1 ohm load. You need to figure out how your going to wire them, then all you need is an amp with at least 180 watts RMS per channel.

The 1030's are 250 wrms, and only come in SVC 4 ohm config's if I remember right.

If you wire them all parallel, youll get 1.33 ohms.
If you wire them all series, youll get 12 ohm(unresonable for car audio pretty much)
Wire 2 in parallel, and one in series and youll get 6 ohm.
Wire two in series and the 3rd one parallel, and youll get uhhhhhhhh, .25ohm???? I think.

So, best thing to do is wire them all in parallel for `1.33 ohms, and find an amp that is like 800 watts at 1 ohm. lol. Finding stuff for odd ohm's like that is a pain.

An amp I can think of would be a JBL BP600.1. Rated at 600wrms @ 1 OR 2 ohm, puts out more like 700.
It would be a pretty good match for those things all wired in parallel.

Although if you do plan on upgrading your system later on you can always go with a bigger amp and then just keep your gains low. maybe 1200w.

Ahh, I knew it was either 4 or .25 ohm. lol

I think there's some misinformation in the responses. Here's the real deal:

A.) Three 4 ohm speakers in series yields 12 ohms. Each speaker will "see" (consume) 1/3 the total power. Because the amplifier is loaded with 12 ohms, total power delivered to the load will be approximately 1/3 the power delivered to a 4 ohm load. In other words, each series speaker will only consume approximately 1/9 the power as it would if it were connected directly to the amplifier. Because total power is only 1/3 the power delivered to 4 ohms, your maximum SPL will decrease approximately 4.7 dB, all else being equal.

B.) Three 4 ohm speakers in parallel yields 1.33 ohms. Assuming the amplifier can continue to behave as a voltage source with such a load, total power consumed by the load will increase threefold. Each speaker will consume the same power as if it were connected directly to the amplifier alone. Maximum SPL capability will increase approximately 4.7 dB compared to a single 4 ohm speaker.

C.) Connecting two speakers in series and the third in parallel across the series pair will yield 2.66 ohms. This configuration, as well as connecting two in parallel and a third in series (6 ohms), is to be avoided. Power consumption between the three drivers is not equal, and the electro/acoustic properties when placed in a common enclosure will also not be the same.

Happy listening! :banana:
