Mike From Maxxsonics:

1. Front ground is best on strut tower bolt which goes directly to your actual frame of the vehicle rather than the flimsy piece of metal most people use. (sand well)
2. Ground in the rear? of the vehicle at the strut tower bolts rather than the flimsy metal as well. (sand well)
3. Fuse the cable from your alt to your pos battery terminal just incase it shorts.

  • When i take my negative off for when im doing whatever. Is it normal for it to spark some when i reattach it?

  • @SubMasterT - Yes, that's completely normal - Just as long a the arc does persist more than 1 second after the initial connection is made.

  • i just cant find the ground for the alternator/engine "/

  • @2sv15039 - You alternator ground IS your engine ground - You need to ground your ENGINE BLOCK to your battery, which in turn grounds the alt...

  • I did this upgrade. it took me 15 mins, and it really works! My lights dont dim at all anymore!

  • @Bigchuck678 - That's my man! GET THAT POWAH!!

  • @EXOcontralto dude. you are a boss. xD

  • Thank you for this video ... big ups

  • Hey bro, i have a question. I have a pair of 600 watt, 5 way pioneer 6x9's installed in my car. For some odd reason the one on the driver side static's, and sound's busted as if it has a shortage. I know the speaker isn't blown because, i experienced this problem with the last pair, and bought these brand new, and have the same problem. It does it on certain song's. I have it connected to an alpine mrp f-300 4 channel. PLEASE get back with me SOON with suggestion's, THNX!!!

  • @wiggster1080 actually he forgot to add a yellow top battery and a higher output alternator. those are the other 2 of the big 3.
