CT-400.1D Monoblock Car Amplifier vs Stinger Audio MT-1000.1 Monoblock Class D Car Audio Amplifier
Buy the Stinger MT-1000.1 if you want maximum bass per dollar: it makes 1,000W RMS at 1 ohm for $129.00, against 400W RMS for the CT-400.1D at $119.99. Buy the CT-400.1D if your subwoofer is rated around 300-400W and you want a smaller, strappable amp with a subsonic filter. The $9 price gap makes the Stinger the better value unless you specifically need the CT's compact size or strapping.

Questions and answers
- Which amp is better for a 1,000W subwoofer?
- The Stinger MT-1000.1. It is rated 1,000W RMS at 1 ohm, while the CT-400.1D tops out at 400W RMS at 1 ohm.
- Is the Stinger worth the extra $9?
- Yes for most shoppers. At $129.00 it delivers more than twice the 1-ohm power of the CT-400.1D at $119.99, plus a published -93dB signal-to-noise ratio.
- Which is better for a small sub setup?
- The CT-400.1D. Its 400W at 1 ohm and 300W at 2 ohms suit a single sub rated around 300-400W, and its smaller chassis fits tighter spaces.
- Does the CT-400.1D have a subsonic filter?
- Yes. It has a low pass filter, subsonic filter and bass boost, which the Stinger listing does not mention.
- Can I run either amp at 4 ohms?
- Yes. The CT-400.1D makes 150W at 4 ohms and the Stinger makes 400W at 4 ohms, so the Stinger keeps more headroom at higher impedance.
- Which has the better bass knob?
- Both include a remote bass knob and cable. CT-400.1D buyers complain theirs is poor quality; the Stinger includes a mounting bracket and screws.
