Hertz DPower4 - 4 channel amp

The following review is for DPower 4, which is a part of the bundle you are viewing.

Nice compact amp. Sounds pretty good but does leave a bit more power to be desired. After reviewing the Hertz website, the specs for this amp rate the 14.4v power output at both 1 and 10% THD. I am not sure how 10% THD is invoked or if this is a common configuration but that sounds like a lot of distortion. I am running it at 4x4ohms. I would also prefer direct connect terminals instead of requiring spade connectors for all connections.
