Car audio question on a amp?

Car audio question about performance teknique 800 watt amp?

• ok can anyone tell me what this means and what is my amp capable Maximum Output Power @ 2 Ohms: 400W x 2CH Power Output @ 2 Ohms: 175W x 2CH Power Output @ 4 Ohms: 125W x 2CH Power Output Bridged: 350W x 1CH THD: 0.05% Signal to Noise Ratio: >95dB Frequency Response: 15Hz to 40kHz Crossover: Separates High-pass: 50Hz to 1kHz Variable Low-pass: 30Hz to 500Hz Variable Slope: 24dB Octave Subsonic Filter: 10Hz to 100Hz Variable Bass Boost: 0 dB to 18dB Variable Input Sensitivity: 200mV to 6V Variable Low level Input Impedance: 47K Ohm Damping Factor: 180 into 4 Ohm Channel Separation: >80dB High & Low Level Input through RCA Double Sided PCS Dual Protection (Thermal & Short Circuit) RCA Line Out Power & Diagnostic LED Indicator 2 Ohm Stable Soft Delayed Power On Tri-Mode Capability Power Supply Consumption (Bridged RMS): 36A Fuse Rating: 20Ax2 Dimension (WxHxL): 9.96" x 2.12" x 15.90" yeah cause i feel my amp really underpowered for some reason it is berly pushing my l5 12inch kicker any help would be appreciated thanks for help

• Answer:

  It is barely pushing that L5 because that amp is pushing less than 1/3rd of the max power for that speaker. For the 12" L5 the rated power is 1200w max / 600w RMS. With the amp specs you have given the maximum output power is listed as 400w, generally RMS is half that in most cases. That would be 200w RMS and that sub requires 3x that amount. If the sub is 4 ohm dual voice coil, wire them in parallel to get that down to 2 ohms and that should give you a little more bang, other than that give that sub a bigger amp to feed it more power.
