At first I really liked this amp as the Highs/High Mids are wonderful. I had no problems until I recently had trouble with my Hifonics brutus hifi2500d. Since i had problems i removed my subs and amp until i can figure out what happened. This is where this amp comes into place. I messed with it a little to get more bass out of my 6.5 alpine type r (in doors) and alpine type s (in rear panels). I've tried everything to make sure i have the right airspace behind all speakers including pods and dynomating. The mids to low mids are very choppy and sound as if the speakers are distorting. It's very annoying. And to top it all off, i can only turn my volume up halfway on the amp and from my clarion eq without distortion and even then about 15 minutes listening time at those volumes will cause my amp to over heat and go into protection mode. I have it in a huge open space where it is extremely easy for air to get to the amp to cool it down. i've even tried keeping it turned off with the ac blasting until it gets pretty chilly in my car and it still over heats and turns off only giving me maybe 2 more minutes max. I like listening to rock music at a pretty decently high level of sound. but in order for me to have non stop music i have to have the volume only turned to 1/4 volume. Kinda stinks. For 150 bux you cant ask much from an amp but im pretty sure i should be getting better than that. I've also tried calling hifonics considering there are no dealers near me and left my phone number and all the detail i can in a message. After at least 5 calls and 3 messages i havent heard back from them. I think in the near future im going to save up and get an alpine pdx series. If you like your highs and high mids to go with your subs this is an alright choice. If you like quality, just look a little deeper into your choices as i did not and am not happy with my choice. Oh and i've had this amp for about 3 months now.
