Amp question

Hello all. I have a 600 watt sony amp pushing two pioneer 12's. The amp is grounded with two diff. wires to the truck. The places they r at was ground down to bare metal. The reason for two was, whenever I push it real hard the amp gets hot and cuts out. A friend told Me to ground it better. I did this and it keeps cutting out when it gets hot. I have a fan blowing on it to keep it cool and it doesnt do that. And the amp is mounted on the back wall. It has plenty air flow. I want to get away from using the fan. Any ideas?

Turn the gain on your amp down..Yes, having it all the way up gives you more bass at a lower volume level, but it increases the risk of blowing the fuse, and as you have encountered, overheating your amp.

Also make sure if your driving two subs that your amp is 2ohm stable if not that will also cause it to overheat. It will also damage your amp. a nice website on car audio is http://www.bcae1.com/

it is a 4 channel amp that I bridged. using the pos. off one leg and the neg off the other side. thus using two channels to run one speaker. Only when it is cranked for about 20 mins or so is when it starts cutting out(getting hot). If u keep it low or halfway it will play all day long without cutting out.

If you have a good head unit, Good amp Good subs you wont need to turn the gain up. I hear a lot of people who just make noise with there system so much bass you can not hear anything else, Just a waste of time and money, I had a car with all infinity, Subs amps and Speakers, two 10" Kappa Perfects, fed 750 watts RMS and 4 5x7 Kappa's fed 120watts RMS Both amps were infinity.


do it right and it will sound clean and in my own opinion clean sounds better than loud.
