SLAPZ Car Audio Mini 160.4 micro amplifier 160 x 4 channel
Feedback is limited to 10 ratings at 4.8 out of 5, so treat the score as early signal rather than a track record. Owners mostly mention the small size and the power for the money.
Pros
- Small size makes it easy to hide
Questions and answers
- Which is better for powering a subwoofer?
- The Stinger. Bridged it makes 500W x 2 at 4 ohms versus 320W x 2 for the SLAPZ, so it drives a sub with more headroom.
- Which is easier to fit in a small car?
- The SLAPZ. At 7" x 5.3" x 2" and 2.8 lbs it fits behind a dash or under a seat where the full-size Stinger will not.
- Is the Stinger worth the extra money?
- Yes if you need the power. It costs $119.00 at Best Buy versus $109.99 for the SLAPZ and delivers about 360W more total RMS.
- Which has cleaner sound on paper?
- The SLAPZ, with a S/N ratio above 105dB and THD+N under 0.01%. The Stinger is rated -90dB, which is adequate but lower.
- Do both run on a standard 12V car electrical system?
- Yes. Both are rated for 9V to 16V operating voltage, so either works on a normal 12V system.
- Which handles high-voltage line drivers better?
- The Stinger, with input sensitivity up to 11V versus 6V for the SLAPZ.
