When you want an amp that's truly versatile, it's hard to go wrong with the 6-channel Infinity Reference 5761a.

You can contour the output to suit your speaker setup with the variable high- and low-pass filters. Kick up the bass output with Infinity's Variable Bass EQ when you need a little extra impact. Speaker- and preamp-level inputs ensure this amp integrates smoothly into your system.
