I bought a pioneer 800 wt amp several months ago along with 2 10 in rockford fosgate p1's, They worked awsome for at leat 6 months. Recently I installed 4 rockford fosgate interior speakers and a 1.6 farad capacitor. That worked fine for about 2 weeks until I was listening to music and the subs stopped working. I checked the cap and it read "lo" when usually it says 12.2 to 10.4. When the car is running with the cd player off the cap reads 12.2 but when the cd player is on it reads lo. Any suggestions would help me so much.
