The “Big 3” is a very simple mod to your automotive’s electrical system that may assist it keep greater voltages for extra energy hungry amplifiers. For those who’ve ever measured your voltage drop when enjoying music with the amount to the max together with your engine operating, you will see that as an alternative of studying 14.4v or 13.8 (relying on automotive), your voltmeter will learn 13v, 12v, and even decrease! You may simply inform in the event you’re experiencing these voltage drops by watching your headlights. In the event that they dim whereas enjoying your system, you most positively have voltage drop occurring. This voltage drop may doubtlessly trigger hurt to your amp whether it is important sufficient. I had a Treo SSX 1500.1 blow as a result of I used to be letting my voltage drop to about 9-10v, which the amp did not like very a lot.
What causes this downside are the inventory, small gauge wires used to attach varied electrical elements. The inventory wire is often 8 gauge, which is adequate sufficient for roughly 50 amps. Massive amplifiers can pull up and over 200-300amps, so now you see the issue.
When doing this mod, 3 runs of wire will should be put in. They’re:
- Battery constructive (+) to alternator – From the constructive terminal in your battery to the alternator constructive (+) put up
- Engine block to chassis floor – From engine block to chasis. That is to strengthen the bottom.
- Battery floor (-) to chassis floor – From the detrimental terminal in your battery to your automotive’s chassis.
I like to recommend utilizing 1/0 gauge wire. You possibly can use 4 gauge wire if that is all you could have laying round, however you may as properly use 1/0 the primary time so you will not have to return in the event you determine to improve your system in a while down the street. The wire I used was Knu Konceptz 1/0 Kollosus Kable Additionally, you will want 1/0 ring terminals to terminate the ends of the wire.
Earlier than you do something, make certain to be protected. Disconnect the wire from the detrimental terminal of your battery earlier than you start. This makes an incomplete circuit and retains you protected from sustaining electrical accidents.
First, measure a size of wire to go out of your battery constructive (+) terminal to your alternator. Ensure to depart a little bit little bit of slack, round 6 inches, so you’ll place the cable freely. Terminate the ends of the cable with ring terminals, then join the wire from battery constructive (+) terminal to your alternator. There could also be a plastic tab on the alternator put up. If there may be, go forward and break it off; it is what I needed to do. For those who do not take away the plastic tab, you will not be capable of take away the nut off of the terminal put up.
Including a fuse to go in between the battery constructive (+) and the alternator is very advisable, however not needed. There’s a small likelihood that the wire will come lose and brief out, nevertheless it’s an opportunity some folks don’t wish to take. Quite the opposite, I’ve had no issues within the 2 years I’ve had the massive 3 put in whereas operating an unfused wire.
The subsequent step is to run a wire out of your engine block to your automotive’s chassis. This step could also be troublesome as a result of you might have a tough time discovering a spot on the engine block to connect your wire. Search for a non-essential bolt; don’t use a bolt that holds fluids again.
From there, you then want to connect the opposite finish of the wire to your chassis floor location. This floor could be anyplace in your automotive’s chassis/body, however just remember to have metal-to-metal contact with the terminal and your floor location. begin is to observe your inventory floor wire again to its grounding location. If there may be paint on the bottom location you could have chosen, you will need to sand it off till it’s naked metallic to make sure minimal electrical resistance.
Lastly, the ultimate step is to run a wire out of your battery’s floor (-) terminal to the bottom location on the chassis. Measure the wire and make sure you go away a little bit slack in case you want it. Then terminate the ends with ring terminals and fasten one finish to the detrimental terminal and the opposite to your grounding location in your chassis (as seen above).
After getting made the brand new, beefier battery floor, you’ll be able to lower off, disconnect, do no matter you wish to the inventory floor wire as a result of it’s not wanted anymore. Whenever you assume you are completed, go forward and double test your whole connections ensuring that they’re cosy and tight.
That is it! The “Big 3” is now completed. It is best to discover a distinction in voltage when enjoying your system at max quantity. Earlier than I did this improve, my voltage was at about 10v beneath heavy load. After doing the “Big 3” improve, my voltage beneath heavy load was stabilized at about 11v. Fairly a big distinction for the way a lot you spent on the wire and terminals. That is why the “Big 3” is taken into account the primary electrical improve it is best to do to make sure constant energy to your amplifiers.
