Review on Compact and Powerful: Soundstream ST4.10000D 4-Channel Car Amplifier - 90WX4 by Jamonte Hamilton

A very powerful amplifier with a very small footprint. Installed this small 4 channel amp in my '98 Jeep TJ, since space was limited I had to find a small amp with 4 channel outputs and a stable 2 ohm impedance. This amp fitted perfectly, I built a small platform to mount to a standard jack under the passenger seat (there is a hi-lift so stock jack is not required), vented the platform and placed the amp 3/ 4" keep it as cool as much as possible. The amp worked even better than I expected, after adjusting the crossover and gain points I have an audio system in my jeep that is just AWESOME! The amp will driven by a Kenwood 515 main unit at preamp level, it drives 1 pair of 4-way Boss 6x9 speakers mounted on an arch (rear channels) and a set of JBL component 2-way speakers, in parallel to a pair of Rockford Fosgate 4x6 speakers (front channels) has so far performed flawlessly even in extreme heat, summer in southern Arizona and consistently very high volumes.
