Just signed up and making my first post.
I have a specific question, but first a little about me...
I have installed systems before, but only head units and speakers. I've never installed an amp or crossover.
What I lack in install experience I think I make up for in technical knowledge...to a degree.
I know all the parts of a speaker, I know how they work. I understand impedance (3 years of electronics when I was in high school), I know the laws like ohm's law, how to calculate amperage, voltage, etc, etc.
I understand single vs dual voice coils, wiring series vs parallel to achieve desired impedance, etc.
I know what an amp is, line level vs pre-out from the head unit, what a cross over is and how it works and what it's for, etc.
I understand the thiele small parameters and what they indicate.
I understand the theory of sealed, ported and band-pass sub boxes (and with nearly 25 years of woodworking experience and my own full shop, building a sub enclosure won't be difficult).
But...I have a question about line converters...specifically to use one or not, and here's why...
My Dodge Ram 2500 pickup still has it's stock system. Head unit/cd player and 4 speakers. I'd love nothing more than to rip it all out and go crazy and just take it to a shop and let them do it up (because frankly I HATE running wires and doing wiring...probably why I didn't pursue electronics, heh), but as with all things it's always about the money. I just dropped almost $9,000 on the truck in the last couple months replacing front end parts (ball joints, track bar, u-joints, a lift kit, 35" tires and about $1700 in repairs at the shop I couldn't do myself)...sooooo dropping a couple grand on an all new system is out of the question...at least right now.
So, at this point in time I have $200 that I can use on whatever I want and I decided that some bass would be better than no bass at all. I want to add a sub to my stock system.
So I figured a mono amp, a sub and a box at minimum. I'm not kidding myself that all the components are going to be cheapy, so I apologize to all the enthusiasts ahead of time.
In looking around I discovered that I can possibly add a pair of tweeters, crossovers for the tweets and and a 7 band equalizer (personally I like equalizers).
So far I've looked at the Orion CO500.1 mono amp, an MB Quart 12" sub, some cheap tweeters and crossovers and a 7-band equalizer that will fit in the budget.
The only thing I need to decide is whether or not to use a line converter to run pre-out signal to the amp or just go ahead and use line level (the amp accepts both)?
Since the converter is obviously going to have to be a cheap passive converter, will it make a difference in sound quality vs line level? If so, is it enough to worry about or bother with? So, go with the converter or not?
