Efficient amps...need some advice

[Buck 5,000+ posts]

So my understanding now is that more efficient amp are easier to power. Like using less power as say a similar wattage amp but still putting out the same watts. I have a nine.1 right now. its efficiency is 67% which i don't believe is very efficient at all. my lights dim a lot. so what are some efficient 1500 watt or 3000 watt amps?

i was looking at the sundown 1500 and 3000ds. are these efficient? any help would be greatly appreciated.

how much are you willing to dish out?

DD amps are quite efficient. Sundown also has a pretty good efficiency rating

I'd say the AQ amps are VERY efficient, I have 2 AQ 2200's strapped @ 2 ohms, with stock 150amp alternator, big3, optima yellow top up front, deka intimidator g31 rear, 2 runs of 1/0 knu klmx, and I don't drop below 12. hell, I don't even drop below 13 without lights. When my lights are on I drop to about 12.6

I thought the exile x2400.1 was pretty efficient.

I second the AQ2200D. I run one at 1 ohm off a stock 140 alt. Plus I run another 6 amps as well. Voltage stays at 13.5-14.2.

I believe eff's is around 86% on that aq amp.

Not to mention its a beast.

The MMats are very good as well.

Also JL's 1000/1, but thats not a lot of power.

i have kickerzx1500 and wondering how efficient kicker amps are

I think Autotek MM series are pretty efficient.

I had a kicker kx2500.1 and it was very efficient. There was a test done between like the kx2500.1 orion 2500d and I think IA 20.1 and I want to say the kicker was the most efficient and most powerful of the three. So I'm guessing your zx1500 is also very efficient
