If you are looking for an amplifier to power your sub I don’t think you would need anything other than this one. It has far more power than I’ll ever need but because of that it has plenty of headroom so as not to ever distort at the volume I like. I had no problem installing it even though I haven’t had a lot of experience in that field. Once installed I had no problem dialing in exactly the sound I wanted in my 2014 Prius. I don’t think I could have found a better unit to fit my needs and I most heartedly recommend it!
