I am going to be changing the wires under my hood and doing the big 3 upgrade/ Now my question is, is this going to be easy enough for me to do myself? will everything be easy to get to, because i know its pretty tight under the hood. thanks for the help, below i have the wires i will be upgrading. Let me know if i can do this, and roughly how long it take, thanks again




Upgrade battery ground->chassis
Upgrade alternator/ground->chassis
Upgrade alternator/power->battery

 

for what?

 

going from OP's previous post, it's an 04, most likely a sedan (back seat doesn't fold down, if that means anything). Further vehicle details were requested, none were provided.

MOD- Can we make a sticky about what information we pretty much need to offer ANY help?

 

weve tried that...for a long time...we cant make people tell us stuff that they should know would be helpful...but hopefully the OP will give us some more info to help him out.

 

Unplug your battery first obviously.

I don't think it would be hard unless you can't reach certain grounds.
I just got an R/T today and only briefly looked under the hood. It looked pretty cramped in there compared to my Civic lol. So you might have to take a few other things out first, but it should still be relatively easy.

 

let me know what you need, and i will do my best to tell you, im upgrading all the wires because im running 1200 watts of current to an amp in the trunk from the stock battery, and i have alot of dimming issues, this should hopefully fix them. And yes, i have an '04 Sedan, and i figured out how to fold the seat down, thanks guys, but im stuck now lol, also, i was wondering if i need to fuse the wire im going to be running from +battery to alternator

 

Ok... I'll tell you where i'm coming from. I had a '99 kia that I used to do IASCA competition (135.4db w/800w spring of 2003 [thunder in the park, watertown, ny]). Afterwards, I upgraded to an infinity 1200a mono block amp and an infinity 600a stereo amp. From the battery (yellowtop) I had a 3inch run to a 150-amp fuse block. That is CRITICAL if you don't want to potentially set your car on fire (NO insurance will cover fire caused by aftermarket wiring). I was running a 2gu power wire. The power wire ran down into the trunk, where it went to a 3 way splitter. 1 line ran to the 600a, the other 2 ran into the 1200a. The amps were grounded to the body of the trunk with about 3 inches of 4gu power wire (grounds work better when they are SHORTER). I had serious dimming issues with the stock battery, and upgrading to the yellowtop made a huge difference. I also had a 1.2farad capacitor mounted inline with the 1200a's power wire that eliminated the rest of the dimming issues. I was unofficially metered after the upgrades at 143.1db by a local audio shop.
Upgrading the wiring from your battery to grounds is a nice measure, but won't help nearly as much as plunking down some change on a GOOD battery, and a high amperage alternator. If you live where it gets cold, the upgrades help on those frigid mornings too.
