I was pretty much saying for the price range and power the lanzer are good.
You can get a less powerful more expensive amp or a real expensive more powereful amp.
Im poor so a 1000rms for $150 will make me happy, Sure the alpine will kick its *** but its $600 more.
I do think the legacy are garbage but basicly a big brands rms will be closer to its max then a cheap ones. So if you pay attetion to it you might get a steal.
example: A kenwood 800 max might push 200x2 rms maybe 500 bridged. $180
A lanzer 2000 max might push 300x2 maybe 800 bridged. $130
If you go by max it wont help, You go by rms youll have a better understanding of its power. You go by price and rms youll know what your paying for.
