[QUOTE="RosedaleGuy, post: 7724878, member: 641381"] I had an audio shop upgrade the sound on my 09 MDX. He left the factory amp in to power the rear and front speakers but added an MRX F-65 to power the side speakers and subwoofer. Everything was fine but then I had him upgrade the side speakers to component Alpine SPR-175. One thing I noticed after the upgrade was that I have to crank the volume up much more than I did with the factory speakers. I guess the small factory speakers are more efficient. But then the sub blew on me. I thought maybe it was because my girl maxed the volume. The sound guy replaced the sub today. Now today it seems it blew out again. I had the sub and base set very low, never maxed the volume (0-40) I went to 32. It seems like I was playing music, the Nav sound took over, and I could hear the sub making an awful sound while the Nav voice was directing me. Now this new sub (10" Helix) seems blown. 1. What is going on here? 2. Is there something I can add to prevent the sub from ever blowing out? 3. Is this guy doing a bad job? He seems to know what he's talking about. It seems to me that the sub is getting way too much power. If I raise the sound volume so the music is loud the sub gets too much power and blows? Any help would be appreciated. [/QUOTE]
