Where this amp fits in your build

We'd consider this amp if you need four channels of amplification with a compact footprint. It's rated 4x300 watts RMS at 4 ohms, with the same 4x300 RMS rating at 2 ohms, so it can drive four speakers or two subwoofers. The Class D design keeps it small enough for tight installs.

The matte black chassis uses 4-gauge power and ground terminals. Before you buy, confirm you have room for a 4-gauge wiring kit and that your speakers or subs match the per-channel impedance you plan to use.

What it will not do

This is an amplifier, not a fix for weak electrical or poor source signal. Those issues need their own solutions.

It also does not include a wiring kit, so you'll need to supply power wire, ground, fuses and signal cables separately.

No wiring or installation accessories are included with the amp

At $309.95, this amp is $37.60 below the typical price over the last 90 days of $347.55. That's an 11 percent difference.

That's a typical-price buy, with the current figure sitting under the 90-day typical.

Power, wiring and space checks

Confirm your charging system can support the current draw this amp will pull at your planned power levels. The 4-gauge terminals set the wiring size, but the fuse rating and alternator output are separate questions you'll need to answer for your vehicle.

Measure the mounting area first. The compact chassis is a selling point, but you still need clearance for airflow and access to the terminals. Also verify your head unit has the needed preamp outputs and that you have line-out converters if it doesn't.

Who should choose this amp

Choose it if you want a compact four-channel Class D amp with flexible power ratings for a speaker-and-sub setup, and if the $309.95 price fits your budget. The adjustable crossovers give you tuning options without adding external processors.

Skip it if you want a wiring kit included in the box or if you need more bridged output than this amplifier is rated for.
