Great package -  easy to buy the speakers and the amp together.  This is still working great after 6 months of daily use. I used this to replace the Infinity Gold amp in my 1998 Grand Cherokee. I did need to install a ground-loop noise isolator (PAC SNI-1) to get rid of the alternator sound. Installed under the rear seat with no ventilation.

Great package, great value

[This review was collected as part of a promotion.] the amplifier and speaker setup sounds good together and the amplifier isn't huge so it's easy to tuck away

impressive for the price
