Well...I ended up switching over to four 15'' DD 3500s and 4 Kicker amps.Your electrical should be fine running on a 200 amp alternator but I'm guessing that it's not.How many volts is your alternator producing right now?You might need a better ground even if you think you have a good one right now.Use a digital multi meter and test the positive terminal of your alternator and ground the meter at where your ground wire is see what you're getting and then go from there.
