Ask Me Anything About Audio System Design
Hello
All, I am jam packed with audio system design and calibration knowledge that is undoubtly of value to most of you!
If you want some real answers, post your question, but be ready for indepth answers!
Put me to the test!

Planning dual audison lrx 5.1 build with a DEX-P99RS with focal k3p, with dual 6 1/4 midbass. Unsure of sub, maybe JL 13W-7 (obviously ported tuned low). 4 way active. 50 watts mid and tweet, 160 dual mid bass, 1100ish per coil on the JL. Chevy colorado, regular cab. Think I can squeeze 3 cubic feet, for box fibreglass. How many runs of 0/1 gauge? Already own all equipment. All responses welcome. (Yeah I'm a lurker) TIA.

Here's one. I have 2 batteries in van. One in front, one in back. The vehicle has "Big 3" completed in 1/0. I have 2 runs of 1/0 connecting the batts grounds together + one 1/0 from rear batt to body ground. 1-2/0, + 1-1/0 connecting the pos batt terminals together. Then I have 2 1/0 runs of pos/neg connected to rear batt for sub amp (Atomic 7K) and one run of 4ga pos/neg for the highs amp (RF Power 800.4).
Question is... why is it that when I clamp the power in on amp, sometimes shows a (-) amperage. Also if I clamp other lines, some read (+), others read (-) amperage. The two positive lines should have similar amperage draw correct? Why would one be (+) and the other show (-) readings?? Then if I wait a lil and test again there might be no (-) draw showing, or one of the other lines will show (-), and the other one will show (+). Hell, last time I checked both the positive lines were clamping (-) amperage??
Totally confused...

Hey, welcome to the site. We don't really have an introduction section so how about you tell us a little more about yourself?

so I've got 4 12''s in a box on a 3k watt amp. I'm planning on adding two batteries and replacing my starting battery to give me 3 in total. wiring will all be changed from 2 guage to 0 in the near future. I need to hit above 150. if possible enough to bass race a 49.9. its gonna be for daily driving, so I need the loudest box possible.
or
I have an issue with a turn off thump. thats not the thing that bothers me though. it seems I have a hum from the subs, but its not constant. I only hear it at lower volumes but that might be because its drowned out by music. and it doesn't stay for long, it just comes and goes as it pleases. I've tried a ground loop isolator, but that seemed to reduce the loudness of lower bass notes and increase the loudness of higher bass notes. I've also tried grounding the rcas but that didn't help. I've been told there is a fuse in my deck that may have popped, causing the problem. I need to know what it is.
