One of the trickiest things in upgrading the audio system of a modern vehicle is the lack of space in the rear. Upgrading an Infiniti G37 is not that easy when you want to save the spare tyre. Thanks to class D topology, these (smaller) amps match their big brothers in power and rival them in quality. My ears still demand the sweet sound of a class A amp but when you're in a motor vehicle surrounded by road noise and annoying passengers, it makes it a little difficult to enjoy that smooth audio. This amp replaces my old Rockford Fosgate Punch P850.4, a class AB beast, whose total harmonic distortion is 0.08%. Quite the workhorse but since I now have a car with a backseat that folds down, the amp is just too big to mount anywhere if I don't want to lose any boot/trunk space. So enter the T800-4ad, which is the modern day class AD equivalent, only smaller. The total harmonic distortion is rated at 0.1% so it's not a hell of a lot dirtier than my old amp. Its more compact design makes it possible to mount it in an inconspicuous place and given the efficiency of the amp's class D topology, less heat is produced and that makes it a little more forgiving in terms of installation space. Of course, it's ideal to have at least one inch of space from every side of the amp where possible but even so, that's more forgiving than what the old class AB amps would allow for before they'd start to overheat at high volumes. Don't let the small size of this amp fool you though. It produces a rated 800WRMS total into 1 ohm loads and that's a guaranteed minimum. Mine arrived with a birthsheet quoting 939WRMS - not that I'll need to use THAT much power. In fact, I'm still driving 4 ohm Boston Acoustic speakers (ProSeries and SPZ series) which means I get a rated 100WRMS per channel and that's plenty. Quality is more than just what's on paper though. That's just the first step in the right direction. The proof of the pudding is always in the tasting and I can safely say that since installing this guy, it has proven itself to definitely have a cleaner power supply given the lack of alternator buzz I used to get from the old P850.4. My previous Sony XM-754HX 4-channel only had 75WRMS to give in each of its 4-channels but I never needed to add any external filtering components. The old RF P850.4 did need some modification on my part to correct this and as an engineer, I can say I was disappointed in this one area. Once modified though, the amp always did me proud. So it could be inherent of the class D topology that RF have vastly improved their product's power supply. All I know is, to the ears, it's one very clean amplifier, packs a mean hit of power and has quite the transparent sound, meaning you can flavour your music the way you want to hear it. I flavour mine with a JBL MS-8 DSP, for what it's worth. Whatever your intentions are for this amp, it can and will do what you hope it to. I'll grant you, there are much better amps out there but they cost a hell of a lot more, are a hell of a lot larger and unless you're planning on winning trophies with them in the next competition or you drive an S-class Mercedes or Rolls Royce with an ultra-quiet cabin, they're a waste of money. Great value, great sound and a great size makes this amp ideal for an upgrade in any modern vehicle.Read full review
