its a good chance its the line out converter. I've had troubles with those in the past. What brand did you buy because the quality of those can also make a difference in your sound. I used some sosche ones before that picked up a LOT of noise and caused really bad alternator whine, replacing those fixed a few problems for me so that could be it as well.
its a rockford fosgate. My amp has speaker-level inputs, so the first thing I'll probably try is to use those instead of the external one and see if that works. If that works, I can return like $45 of stuff (hopefully).
you install it like any amplifier. ground the - terminal, and wire the + terminal to your distribution block.
the two important specifications are capacitance and electrical series resistance. capacitance is relatively simple to understand, the higher the capacitance, the higher potential charge storage. the ESR is the speed at which that charge can be delivered.
Did you know your cell phone has several one farad capacitors in it? they wouldnt work very well for audio usage, their ESR is way too big! one way to lower ht eESR is done through some sort of engineering that I dont understand, but its manifested through the size of the capacitor. so you can *kind of* get an idea of ESR by phisical size. two capacitors of the same capacitance but of difference sizes *should* be indicative of which has a lower ESR. ESR is usually not advertized in big letters on the box like capacitance is.
realistically, any capacitor designed for audio use will work, and the higher capacitance, the better. I have a two farad capacitor, and when it was in my car, I never had any light dimming. ever
its not really a factor most of the time, ive noticed. We did that as standard practice at my shop and we didnt get any noise 90% of the time.
but its a definite potential culprit if you happen to have alternator whine.
Road noise is the noise you get from driving. ever notice that a mercedes has a quieter cabin than a gutted civic, both going 70 on the freeway? thats road noise!
I found that grommet, and I *think* I found where it comes out in the engine bay. My questions are:
That grommet is PACKED, I mean no room at all. There's a bundle of wires going through the center hole. There are two side holes as well (smaller).
- Can I go through the holes on the side?
- What are the possibilities of hitting and damaging a wire in that bundle with a coathanger?
- Assuming I wire from the inside out, How am I supposed to grab the wire in the engine bay? It's behind all sorts of crap.
Also, this may have been asked before but I can't read through this thread : How big a fuse do I need if my amp has 2 20A fuses in it already?
...This is a 2003 sedan, dunno if that changes anything.
The grommet in my car wasn't packed at all. I'd be surprised if that changed between models. Be sure you're looking in the right spot. And if you're unsure about where the grommet is in the engine bay you can always get a coat hanger and carefullly push it through and then use it to feed the wire back into the car. Thats what I did to get mine done.
Hate to bring up old topics but I need some help on running the wires (power rcas, and remote). I have the power through the firewall, is there anything on the passenger side to keep the wire from? As far as running the wires through the car how do you get the trim pieces pulled up by the door and in the rear cabin. The car is a 2k4 coupe ex. Any & all help is greatly appriciated.
bty: are there any pics of the whole install process, i searched but couldn't really find anything

Ill try to take a pix tomorrow if I remember. And point out where the gromet is.

Run the wire from the gromet, under the carpet, the door pieces just pull straight out. Dont be afraid, just pull hard!!! Believe me. Then you'll have to lift up or take out (what I did) the rear seats. And just feed the wires under the carpet and up the body frame.
