Hifonics HFi2000D (HFi 2000D) Class D Monoblock Car Amplifier/Amp

MB Quart ONX1.1500D - ONYX Class D Monoblock Car Amplifier/Amp

I need a amp that does around 1000 watt rms to power two 12 inch audioque sdc2.5s. Are these good amps that will do rated power? I wana the mb quart amp but im kinda wondering why its only 169.99. Also my subs are dual 4's wired parallel to 2 ohms so i need a mono correct? Also is it smart to buy amps off of craigslist? Do they go bad and lose power over time?

get a new ap 1500 ,cheaper too if your are looking for cheap.also 2 dual 4 ohm subs will give an end ohms reading of 1 ohm or 4 ohms , not 2. and yes you need an mono block amp.

Im starting to think the subs are 2 ohm becuase im currently running them off a kenwood kac-7205 and the amps specs are "250 watts at 2 ohms 170 watts at 4ohms. It says nothing about 1 ohm so that means the amp woudnt work with 1 ohm subs correct? Therefore my subs must be 2 ohms.

your amp dont determine what ohm your subs are your subs will determine what ohm load your amp will see. check the coils with a dmm to see what they read

Really? I always heard hifonics made great amps but i guess im wrong haha. Got any opinions on soundstream amps? Saw one earlier that put out 1100 watts rms at 2 ohms and it was 198.99 new.
