  1. Nice! For highs or subs!

    Posted by Brandon on 4th Aug 2017

    I got two of these. Had one running the mids and highs. It's plenty loud and nice and clear. I question if it's actually 150 watts rms per channel. Not because it's weak, but because it's so small. Don't get me wrong , it's loud!! Prolly 100db with door speakers alone. Now, I ordered a second one for my other car. But needed a sub amp for a few weeks in my first car. So I bridged the second one to a couple Of CompVR's 12"s. WOW!! This thing makes a wonderful sub amp. I mean outstanding power. I bet it pushes every bit of 600 watts to each sub at 4ohms bridged. Both amps were set up with a DD-1. I really wasn't expecting it to pound the sh*t out of my Comps. Needless to say I'm happy with both of my Ampere Audio 150.4's. I'm a audio hobby-ist not a pro or competitor. I hope this helps with deciding on this amp. Good luck deciding, so many choices out there. These seem to be great amps with a very small foot print, and run very cool. A little warmer when bridged, but I'd say acceptable. If you think you might like it, I'd say you'll love it. Also heard they have great customer service. Haven't had to try it out myself.

  2. Smaller then I thought

    I have not used this yet but I was surprised at how small it was compared to AQ/SQ 90.4 I previously owned. I have also bought a ampere audio 5k to go with it. I will be running 4 soundqubed super tweeters and 4 crescendo pwx 6.5 on it.
