Bass sometimes cuts off

[Ant Monifah]

I have an infiniti i35 2002 with factory bose speakers and radio installed. It sounds pretty good but whenever I play a song with alot of bass it cuts off only playing jus the door speakers. Idk I even put the bass on the radio to -5 and dont pass 20 on the volume but it still cuts off then comes back on ina few mins. Its so annoying lol does anyone know if its my wiring or anything with my speakers? How can I fix it? Also my ac blew cold air last month and now for some reason it blows only outside air I dont get it because this car has no ac button I just lower the temp to 60°....can anyone help me with this issue also? Thanks so much

I think that's usually and amp draw/ overheating issue. I would check the wiring to and from the amplifier. Here's a link to the FSM chapter for your car. See the stereo stuff starting at page 194 and diagnoses on page 201. Welcome to NICO Club!
