DAMN! I didnt realize what a pain in the backside a do-it-yourself install was...... I HAD A BLAST regardless!!
Anyway, Ive come to 2 dilema's, and would appreciate some incite, advice and or help.
1st, is a power issue. I had some farad caps, and quickly realized they were a waste of money. I have a Crossfire vr1202 amp 2x300w @ 4ohm, 2x600w @ 2ohm and 1200w bridged @ 4ohm. I have it bridged pushing 2 Fosgate 10" 1000w subs. I also have a Fosgate 551s, 2x125w, 550 bridged pushing 2 150w Fosgate 6x9s.
Ive got a 4 gauge wire running to a Distribution block. 2 8 gauge wires going to my Crossfire amp, and 1 8 gauge running to the Fosgate. Needless to say, I have a serious power drain issue. My headlights almost go out completely on deep bass hits; not to mention interior power strains as well.
Ive heard adding a second battery would do the job, or a more powerful battery. Ive been told a high performance alternator would do, but then only to be told a high current alt could fry some of the electrical system if alterations were made to comply. I also believe that as a result of not having enough power, my amps arent pushing their capabilities. Ive heard a Crossfire vr1202 at a car show....... WAAAAYYYYYYY louder than what I have. Then again, HE had a monster box, I have one that fits underneath the backseat of my 2001 F150, XLT. I know the enclosure is as important as the rest, but THAT will be resolved later.
Does anyone have some advice?
Also, as of now, I DO NOT have a fuse! Meaning there is no fuse between the battery and the amps. And the reason is Im not exactly certain on what size I need. Help?
Thanks

 

Bigger alternator, plain and simple. You wont fry anything, the electical devices will only pull the current they need, plus if there is a big spike, well thats what fuses are for.

As for the fuses on your amps power wire, definatley get one soon, and just look at the fuse rating on the amp.For example, if the amp has a 30 amp fuse, put a 30 amp fuse on the power wire. If it has say two 25 amp fuses, put a 50 amp fuse on the power wire(add the fuses rating)

Good luck

 

Dual battery set up it the way to go.......i JUST fried my alternator and battery and am in the middle of setting up 2 batteries....thats the way i would go.gets rid of alot of problems...optima batteries is the way to go with second battery

 

IF your gonna sit there with the car off listening to the music, dual batteries are nice.

When the car is running, the power is being produced by the alternator, not the battery.

 

I'm with bartak on this one. Dual batteries are a "no go" with the stock alternator. They will tax it heavily, cause it to fail prematurely, and then when you are thumbing for a ride home.

Start with the upgraded alternator first, you've nothing to loose this way.
