Compact and convenient, good starter amp for small sub.
By M. Yatabe
This is long because I'm trying to be thorough. I've found that a lot of the reviews for equipment I've seen on Amazon weren't enough info for me when I was trying to make an informed buying decision.I picked one of these amps up from the Blaupunkt eBay seller in "manufacturer refurbished" condition. When it arrived, I was impressed by how small and slim the unit is, but on the downside the cosmetic 'end-caps' that snap onto each end (which serve the purpose of concealing wires) had the tabs broken off during shipping. Not a huge issue, I fixed the broken pieces with superglue, and ended up not using them anyway - mainly due to space constraints, but also because putting on the end-caps makes it harder to access the adjustment knobs.The setup options for this amp are straightforward. There's a three-position switch for Low Pass (for subs), High Pass (to block low frequencies from smaller speakers), and Full Range setting that disables the EQ. Next to the EQ filter switch are the knobs for Low Pass and High Pass crossover points, then a Bass Boost knob, and then the Gain/volume knob. The knobs themselves are accessible by fingers, which is nice when you're accustomed to the necessity of keeping a small screwdriver on hand to adjust the recessed dials on most amps. On the same end as the adjustment knobs there are two sets of RCA jacks; one set of inputs and one for signal pass-through (to use for multi-amp setups.) There's also a remote Bass Control knob, but mine came without that particular part, so I really have nothing to say about that feature. The wiring terminals and onboard fuse are on the opposite end of the amp. Power and Ground terminals are big enough to accept up to 8ga wire, but if you're trying to use any larger gauge wires you'll need to get a stepdown adapter or spade/ring connector.Appearance of this amp is very sleek and clean, flat top with rounded sides. The heat sink fins are actually inside cooling tunnels (no built in fans or forced air) that run along the rounded sides. Effectiveness of the heat sink seems adequate, as I've leaned on this thing pretty hard and it never went into thermal protection mode. On the top there are LED indicators for Power, Clip, and Protect. So they do have lights to warn you when you're clipping and about to melt the circutry, and then a light to tell you that you have melted the circutry... which is nice. While it will handle a 2ohm load in stereo mode, it is NOT recommended that you put any less than a 4ohm load on it while it is in bridged mode.I installed this amp under the front bucket seat of my Tundra with plenty of room to spare. The slim design really works well in this regard. Hooked up in bridged mode (supposed to send 200 watts rms) to a 4ohm single 10" Kicker CVR in a sealed box yields decent results inside my truck. I turned the gain up to about 90% (I don't have a multimeter to check for clipping, it's a cheapo stereo setup so I'm not stressing about dialing it in) with the LPF (low pass filter) point set around 180hz. It's got a clean sound, but not insane levels of power. I believe that this amp will do much better when I've got it hooked up to some door speakers in full-range configuration and a purpose-built mono amp to my subwooferAll in all, this is a great little starter amp for a modest upgrade to a factory system, or if you've got severe space constraints and don't have $900 for a JL Audio HD series amp, this will fit under any seat and provide enough power to a medium sized subwoofer to shake your rearview mirror, though I don't think you'll be impressing the hottie at the bus stop with your car's boom.
