I have 2 12" Kicker Comps and a Rockford P550 amp pushing them.My amp will fade in and out. Wat does that mean?

Question

I also have a boost bass control which does not work that much either. If I do need to replace it, what wattage should i look for.?

Answer 1

your car's electrical system may not be able to handle the system you've got installed.  It depends on the car but especially w/ smaller or foreign cars, you run into that alot.  

the fix is pretty simple.. either go w/ a bigger "deep cycle" battery (if possible) or install a capacitor near the amp... basically it's a secondary unit that holds power.  When the car's electrical system gets low it kicks in extra power to fill in the "gap"

Answer 2

your subs are probably blown and the amp is going in and out of protection

Answer 3

It sounds like you're not getting enough power. First, check you're connections. Make sure you have a good ground. If that's not it, then upgrade the power and ground wires, and get a capacitor. (The cap is just like another battery and it will store power so there is enough to power all the electronics in the vehicle). If nothing else works get a new amp.

Hope this helps
