Hi everyone,
I have an 08 Yaris sedan with an integrated radio. I just ordered Focal components and 6x9's with an Alpine MRPF300 amp to power them. I had a friend who gave me his 2 12" sony xplod subs with the 760 watt amp to power them...I realize the gap in quality there, I have plans to replace the subs very soon. I plan on running a 4ga power wire to the trunk and splitting it off to the two amps.
My question is about the alternator. Is the stock 90 amp alt enough to handle that? If not, what is the recommendation for the problem.
