This Sub + These amps

[sleazebagger 10+ year member]

I'd say get the TC or Audiopulse and run a Sundown Saz-1500 or something. Maybe AQ1200, DD m1a, or something along those lines.

That might be the move. I'm definitely going with the LMS though.

What's the RMS? On an 18 I'd run probably around 2k. I'm not sure if you have the electrical or not though. The AQ2200 would be great then.

yeah, My max power is safely 1700 watts. and I need 600 of that for the front stage. I'm sure a lot of people around here would run 3k on this electrical but I'm not a big fan of replacing batts and alts down the road.

I'm sure running occasional peaks of 2200 watts won't hurt though. just got to watch the meter and do some charging here and there.

I might be wrong but doesn't running at a higher impedance put more of a strain on your electrical system because it's more work to push 1000 watts on an 8 ohm load than it would be at 2 ohms?

you are wrong, how can running at a higher impedance put more strain on your electrical. Think about it at 8 ohms(an example) a amp may put out 500 watts and at 2 oms it puts out 2000 watts, how can 500 watts put more strain on your electrical than 2000 watts. People don't run their amps at 8 ohms because people want more power from their amp so they run it a lower impedance. If you have a dual 4 ohm sub rated at 1000 rms and you have a amp that puts out 1000 rms at 2 ohms, 500 rms at 4 ohms and 250 rms at 8 ohms, why would anyone want to run the amp at 8 ohms when you won't get much power to the sub. Remember the more power you run the more amps it takes to run it, amps is what your altenator is rated for, so again how can lower amperage put more strain on your electrical than higher amperage?

I wasn't comparing it like that, I was saying compare 1000 @ 8 ohms to 1000 @ 2 ohms. There is more resistance at 8 so therefore it would take more amperes to push that kinda power at that impedance, Wouldn't it?

Then I think a SAZ-1500 would be best.

No. In this case the resistance doesn't matter. It's the output the amp is doing, ie the wattage regardless of the ohm load. 1000 watts, at ANY ohm, divided by the voltage the amp is receiving (14vdc) = the amperage the amp is drawing from the electrical system, which in this case would be 71.4 amperes and that's if the amp is 100% efficient, which it is not.

Your difference comes from the class design, A/B, D.

1000 watts A/B ~65% efficient would = 109.8 amperes

1000 watts D ~85% efficient would = 84 amperes

That's where the efficiency is, the class D circuitry not the resistance of the speaker/s.

And the Kronos amps aren't strappable. They're 1000 x 1 @ 4 ohms bridged and that's it. Even if they where stappable the ohms would double as well as the power. It wouldn't go to 2 ohms for 2000 watts, but 8 ohms at 2000 watts. It's just like bridging 2 chs of an amp, the ohm loads that each ch sees are combined as well as the power.

So the best bet would be to get a 4ohm DVC and 1 Kronos gain matched to each coil.

You should also consider the Pro 5100 Neo if you're limited on power, it has very high sensitivity, still drops very low in the right enclosure and has tremendous slam in a car.

The car's charging system doesn't care what impedance your speakers are wired up to your amp at. All the charging system cares is the current draw from the amplifier. 1000 watts @ 14.4v @ 4ohms will place the same strain on your charging system as will 1000 watts @ 14.4v @ 8ohms (assuming same efficiency amplifiers being compared).

TC officially went bankrupt, and the owner (Thilo) opened up under a new name (Audiopulse) to avoid some legal responsibilities and debts. One is or was not owned by the other, they were/are separate entities legally, but in reality are the same company. I recently heard Audiopulse is gone and Thilo went back to TC Sounds, but I havent confirmed that yet.

An LMS is going to be wanting somewhere in the neighborhood of 2500 watts (rms) to be happy iirc. No, you wont be doing this system justice by running it on your stock charging system. No sense paying for the biggest system you can afford if you are going to skimp on the power to supply it. Might as well save your money and go with a smaller system, unless you are just buying these products for some sort of bragging rights.

The bankruptcy occurred after AP. AP had nothing to do with legal matters. It was simply a branding solution to migrate to a dealer structure which was never fully developed, hence the bankruptcy . The AP brand has since been depreciated.

You are mistaken. The lower the ohm load, the less efficient the amp is at that ohm load...which is why amp manufactures will list efficiency at 4ohms, since 85% looks better than the ~75% you'll get at 1ohm.
