True amp that sucks

This amp straight sucks hands down the rms rating for it to be bridged at 4ohm@1000watts produce a sound of 250 watts i do not recommend this amp at all.

Does the job!

I have this hooked up to 2 MB Quart RLP304 12 inch subs and it hits really hard. It produces the type of bass that takes your breath away. I have only had one problem with it overheating and that is when I was testing to see how long it could go on full blast. Overall I am very happy with this product. It is small and easy to add to a custom system with limited space. The one thing I wish it had was a remote bass control. Other than that, I like it a lot.

Great Value!

Amp works good, doesnt over heat, but I don't blast my music or over extend the bass so... It was easy to set up, and I haven't had any problems w/ it.

great value

I've owned a few lanzar amps and I never had any trouble with them. I bought this lanzar as a highs amp and it's doing its job. it sounds great I even put it on my 3 kicker cvrs and I was surprised it put out good bass too.
