		The 360a2 is a two-channel amplifier rated at 90 watts per channel into 4 ohms or 360 watts bridged into 4 ohms. Features include bass boost with wired remote, high- and low-pass crossovers, gold-plated, captive-style screw terminals, and line outputs. Also included are a MOSFET power supply and output devices, as well as that infamous heatsink with the fins that would make a ’57 Cadillac feel short-changed. Performance In typical Rockford Fosgate fashion, the 360a2 produces an impressive spec sheet. Perhaps more impressive in this case is the amp’s flexibility. It’s internal crossovers and line outputs offer several obvious advantages, but that’s nothing new. Size is the key, both its physical size and its output potential. To begin with, the 360a2 is a very small 500-watt amplifier. We’ve seen a few switching amps that were smaller, but you won’t find many class A/B units with a smaller footprint. From the power point of view, the 360a2 is also a nice size. We’ve all seen those system diagrams in the manuals that depict a single amp setup driving a pair of components and a sub — 500 watts would be primo in this type of system. In this power range, it still makes sense to power the whole system with a single amp. Single amp systems offer far less complication and a lower price tag. If you wanted to make the system appreciably louder, you’d need about 1000 watts. However, a class A/B amp capable of making 1000 watts is going to be a huge current hog. If you’re looking for the kilowatt range, it makes more sense to go with a class D amp dedicated to the subs and a smaller amp for the components. This puts the 360a2 squarely in the sweet spot. If you decide to go the single amp route, it will provide a substantial amount of power for your system without severe current demands. If a multi-amp system is more to your liking, the 360a2’s internal crossovers will allow it to work at either end of the audio spectrum. Connections & Adjustments All connections to the 360a2 are gold-plated and include 4-gauge power connections, 8-gauge speaker connections, RCA inputs and outputs, and a telephone-style connector for remote bass boost. Adjustments include input sensitivity for each channel, variable bass boost, crossover select, and crossover cutoff frequency control. Installation Installing the 360a2 shouldn’t be a big deal — it’s very small for its output potential and sports a low profile. Under-seat mounting is a distinct possibility, but if you plan to drive subwoofers with this amp, a small fan wouldn’t be a bad idea. The 360a2’s heatsink is a bit small for an amp in this power range. The fact that this amp has been on the market for quite some time with a negligible return rate would indicate that this hasn’t been a huge problem. However, a fan is cheap insurance. Thermal shutdowns never impress the ladies.
