Summary:
This amplifier was installed ina customers lexus with 2 15" Alpine type R's. The amplifier was requested by the customer and it failed within 3 months. Upon examining the amplifier guts, I found it to be very poorly put together and not very efficient, the amplifier would no way be able to put out 1800 RMS as stated, I hope it got to around 1000.

If your looking into a cheap amplifier to power your speakers, go for it, the s/n ratio was horrible on thsi amp, so as by my experience, I would not recomend this amp if you have ever used good products liek focal, JL, boston. You will be very disapointed, but if you don't know any better, go on and grab thsi amp. :D

Strengths:
Price, Looks
