Magic Box!

The following review is for KEY180.4, which is a part of the bundle you are viewing.

Ive used several auto tune dsp's in the past. This is by far the easiest and the best sounding off all! Also don't let the 45watts a channel fool you. It is plenty powerful and gets very loud, and sounds good doing it! I am running a 2way front stage with Silverflute mids and Morel tweeters. Both are rated at 80watts rms and in fact my tweeters are 8ohm. So they are seeing approx 22.5watts to them and they sound very smooth with no fatigue. So if you are on the fence about this amp just buy it and you will have a smile on your face. And let me also point out I have no noise with this amp, no pops,his, or alternator whine. Hope this review helps.

The following review is for KEY180.4, which is a part of the bundle you are viewing.

If you need a small great sounding little amp that’s super easy to use for your highs this is it. It does all the work for you so no adjusting or anything g it’s a plug and play unit.

Great little amp

The following review is for KEY180.4, which is a part of the bundle you are viewing.

made my stock Sync 3 system sound so much better! Combined it with new Kicker speakers, and really improved the quality of sound!

I didnt like the sound stage setting... but the auto equalization was great.. tip is turn down all the treble/mid/low on the radio and then let the unit do its auto equalizing. Then you can add a bit more high/bass as desired.

Works great!

The following review is for KEY180.4, which is a part of the bundle you are viewing.

If you’re looking to use your stock deck and want a lot more output, this is a great piece of kit. We used it in a 2018 Toyota Camary with the stock speakers and another amp. to power a pair of 8” subs in an enclosure in the trunk and it really worked out great.
