Hey Guys Jmanpc has been on this one with me and we can't figure it out.
I am currently experiencing some bad voltage drops, as low as 9 volts when the bass hits, keep in mind this is when the volume is at 85% and when the bass hits hard.
I am running the 500/1 and 300/4 and 2 w3v3 10''s woofers, not really a power sucking system. Anyhow I have the gains set correct at 17 on the 300/4 and the gain on the 500/1 set below 31.v6 (the required setting for my application) and I am still having drops to 9 volts.
Some more things to know.
I have 4guage power wire running from stock battery to distribution block with a ANL 150 mini fuse, where it is then split into 2 8awg for both amps.
I then have the big 3 wired correctly and cleanly with 1/0. With 300a ANL Fuse
I also have redone both grounds for the amps and still have the problems.
Some voltage numbers I acquired from my dmm
-Voltage at battery before and after 4 gauge fuse at battery 14.1
-Voltage at distribution block right before amps and voltage at actual amps with radio turned off : 13.9
-Voltage at distribution block right before amps and voltage at actual amps with radio turned on: : 12.1
-Voltage at 85% volume and heavy bass: 9 and thats where it cuts out.
The car is an 05 accord with a denso stock alt rated at 105 I believe, stock battery, but the battery is 14.1 at the terminals.
What may it be?
Lights still DIM
ok guys here's the video!, sorry for the mess of wires, anyhow you can see the voltage drops, it went to 10, when it is at full tilt it drops to 9. You can hear the music from the car going in and out, music remains playing from the stock tweetrs the car came with since they are still wired, but everything amped goes out which is basically all the speakers.
