Thread: Few Q's about wiring

Any other options other then a cap? So far I have read the Big 3 is a great thing, then I read it was not necessary. I start off assuming a cap could be useful then I read it is useless and just a bandaid fix for a bigger problem.

There is WAY TO MUCH contradiction going on with car audio, I guess it is a try it and see if it works for you kind a thing.

I can't get the volt drop right now as I took my carpet out due to the "water on the floorboard" problem. I reran all my wires while i had it up and haven't got it all put back together yet.

When I get it all setup ill measure the volt drop. Then I'll put a 4ga cable from my alt to my fuse box and do it again to the same song with the same volume just for the hell of it, can't hurt nothing, if it don't do anything I'll take it off, it helps even a little I'll keep it on.

Few more question for you two.
(1) My small amp is cheap (maybe $30, I'll be replacing this when I get the money) would it be enough to cause my dimming seeing how small it is? (I had just my sub amp hooked up for a while before and it never dimmed.)

(2) What is the average draw from an amp on the remote wire? or do you think a relay is necessary on a remote wire? (I'll check mine when I get it all setup)

1) Your bass notes go as high as 300hz which are handled by your mids. A bad amp design can be a heavy tax on the electrical system in your vehicle. I think you found the culprit. However, that doesn't mean go out and buy a new amp. It just means you need to design your power system around that.

2) I wouldn't worry about the remote turn on. Typically installers will tell you it's ok to turn on 2 amps. Personally, I have wired up a relay for my equipment. There's something you should add in case of backfeed to your head unit tho...forgot what it is. I didn't throw it in mine; it's for additional protection.
