|The PA150 is a two-channel amplifier with power ratings of 75 watts x 2 or 300 watts x 1 into 4 ohms and 150 watts x 2 or 500 watts x 1 into 2 ohms. The relatively short list of features includes balanced input circuitry, gold-plated connections, and a beautifully polished heat sink. If you yearn for the old days when an amp was just an amp, the PA150 is right up your alley. You wont find bass boost, internal crossovers, or any of the electronic fluff that have made the modern car audio amplifier so complicated the PA150 is all amplifier.
Electrically speaking, this amp is also very quiet. Signal-to-Noise measured 114 dB and turn on/off noises are well into the single digits at 7.4 and 3 dB SPL, respectively. However, when the amp is powered up, there is an audible, mechanical click that comes from within the amp. A relay I would suspect hardly an issue for most of us.
Overall, this is an impressive package. Many of the amps that we test are designed with an eye towards cutting costs on massive production runs, and on the test bench, it often shows. If youre going to build an amplifier sans all the BS, it only makes sense to build one that works well and looks good doing it. Its obvious from the way that this unit looks, feels, and behaves on the bench that, at Poweramper, the bean counters dont run the design team.
From the installation perspective, the PA150 is small and uncomplicated and should be a delight to work with. However, it does present one potential for aggravation. Fuse access is through the bottom panel of the amp. This means youll be un-installing the amp if you pop one. The fuse access hole is also somewhat small and the fuses are quite close together. My best advice here is to use some type of fuse pulling tool or youll likely drop a fuse into the amplifier, like I did.
