Recommended Posts

Some DD Audio amps. Only two have ever seen power.

Used DD M2a silver finish: $275 shippED SOLD

Used DD S4a silver finish: $275 shippED SOLD

New DD M2a Black finish: $400 shippED

New DD SS3 Silver finish: $200 shippED SOLD

No to trades.

The two used amps barely saw any play time, because the car ended up getting a new motor built and had to have everything out of the trunk so they could do the fuel filter. Maybe 2-3 months use.DSC_0059_zps2ef43bf3.jpgDSC_0083_zps7afc7764.jpgM2aInput Sensitivity0.2V - 8VVariable Subsonic Filter10Hz - 50Hz @ 24dB/OctVariable Low Pass Filter20Hz - 200Hz @ 24dB/OctClipping DisplayLEDTested Voltage11.9 VDCTestedTHD≥1%ModelM2aCont power at 2 ohm1040W x 1chDamping Factor Cont power at 1 ohm 1600W x 1chDynamic Power2920W x 1chEfficiency thru OutputDimensions - mm400L x 232W x 63.5HDimensions - inches15.75L x 9.13W x 2.5LSignal to Noise>100dBDSC_0068_zps43ca7b7f.jpgDSC_0066_zps26047288.jpgDSC_0067_zpsd2335035.jpgLittle foam, but will clean it off.DSC_0084_zps2072b4e7.jpgS4aDSC_0069_zps91d8ed8b.jpgDSC_0071_zpsf3440c40.jpgDSC_0072_zps44ed955d.jpgM2AInput Sensitivity 0.2V - 8VVariable Low Pass Filter 20Hz - 200Hz @ 24dB/OctVariable Sub-sonic Filter 10Hz - 50Hz @ 24dB/OctTested Voltage 11.9 VDC signal to Noise >100dBCont power at 1 ohm 1600W x 1ch BridgedDynamic power 3000w Efficiency thru OutputDSC_0082_zps1f97ea80.jpgDSC_0076_zps4bb732bf.jpgDSC_0080_zpsf28d97cf.jpgDSC_0074_zps7769fd8c.jpgSS3DSC_0061_zpsa03c71b6.jpgDSC_0060_zps3af79f1d.jpgDSC_0062_zpsa4f998e2.jpgDSC_0063_zps4a78c2fe.jpgAmps will be cleaned off and sorry for some blurry pictures.

he wouldnt be the first to say they did a 167 with a system like that (one that clearly DOESNT), but i have to say, he didnt beat me anywhere, ive never competed against the guy. If he thinks his does a 167, mine would probably put him in a coma. :hairtrick:
