Rockford Fosgate Power Stage 1 T115D4 Review
Rockford Fosgate Power Stage 1 T115D4 car subwoofer review. The new Power Stage 1 T115D4 is just a beast of a 15″ subwoofer. A lot of people have been asking for reviews of Rockford Fosgate and I decided that the Rockford Fosgate Power Stage 1 T115D4 would be a great start. This sub slams, very hard. A lot of reviews that I have read online agree as well.
The Power Stage 1 T115D4 is a 15″ subwoofer with a RMS rating of 600W and a peak rating of 1200W, so will need a amp with some power to push one of these subwoofers. There are a lot of great things to say about this subwoofer. The Power Stage 1 T115D4 has a huge double-stacked magnet at 220oz. The basket of the sub is designed to help it stay cool. This is a great feature for letting you play the subwoofers longer and loader with out having to worry about the subwoofer over heating. Custom compression terminals accept up to 8-gauge wire. Remember with buying this sub that it is 4 ohms and needs a lot of power to push, keep this is mend with wiring options you are going to be using and the ohm load that it will produce. Depending on your set up it may be better to go with the Rockford Fosgate Power Stage 1 T115D2
