This, much like the subwoofer, is an area where lots of research was done. Much like the subwoofer, there were requirements in an amplifier. Those requirements are as follows;
1. At least 2 ohm stable.
2. A minimum of 300 watts RMS of true power, not just rated power.
3. Small physical size. The amp MUST be able to fit completely under the passenger seat with room to spare, and preferably be slim enough that the under seat HVAC vent can stay in place.
4. Low amp draw. Even though it appears as though the electrical system on the Niro can handle 50+ amps of current, I want to limit this to only 30 amps. This means the amp needs to be a Class D type.
So after an exhaustive search, one amp stood above the rest. What worried me is the brand of this amplifier. Power Acoustic. They are not known for making quality equipment.
More searching revealed this amp being tested on an amp dyno. This tests the true power output, not just what a manufacturer says what the power will be. So this little amp produced about 450 watts at 4 ohms and about 650 watts at 2 ohms. More than enough.
Then I discovered another very nice tidbit about this amp. It is made in Korea! So why does this matter? Typically, amps made it Korea have better quality control and are made with better components compared to cheap made in China amps.
The model of the amp is RZ1-2300D. The last nice surprise is this amp can be bought from any local WalMart for $97. It has speaker level inputs which will be used, and it also has a remote level bass knob that will also be used.
