Some guidance for good sound?



Looking for some guidance for decent sound.
I have never done anything stero beore and am quite convoluted with all the Ohm, Impedance, RMS etc. I just don't get it....

Can someone give some guidance here on an install?

Here is what I have:

2-4x6 Pioneer in the dash
2-4" in the soundbar
2-6x9 in pods behind the seats
2-8" subs
1-4 channel amp
1 Pioneer deck with wiring harness connected as it should be, one set of preouts
Power distribution block
Capacitor
Fuse holder for power to the amp

Currently, the fronts and soundbar are wired off the deck and harness.
I ran a power wire and remote wire along with a set of RCA's off the deck to where I want the amp.

How do I get best sound out of this coniguration?
Do i split the preout on the deck to run two sets of RCA's to the amp and then use the amp to run only the 6x9's and the 8" subs?

Do I really need another amp to run the 4x6s and 4"s?

The amp has two inputs on it, front and rear.....do I have to split my preout off the deck?

I have NO IDEA what I am doing....please god, someone help me, this 'aint like changing leaf springs at all!!!

OK, it has been a while since I dabbled in car audio installs, so I will do my best. I am sure others will correct what they see fit to :P

For the wiring, you are gonna go 8ga pos batt to a fuse within a foot or so, then on to the amp. Ground with an 8ga local to the amp, within 3' of it. Run the rca and remote lines like you did, lol, then hook em up.
Are your 6x9s componants or just woofers? The output from the hu will be a sub output, so it really should only supply low end freq speakers. If that is the case, run the rca and split it to power the 8s and 6x9s off the amp, and leave the hu powering the 4s and 4x6s. Not ideal, but it will work and be loud.

Your amp may be able to be bridged down, providing more power to the speakers by acting as a 1 or 2 ch amp. If you have componant 6x9s (with other speakers attached to them) you may want to get another amp, run the 8s off 1 and the mids/highs off the other.

I would go buy an amp for the 8s and use the 4ch for the rest, running the 6x9s and 4s on the same channel, assuming componants. I would use the 4ch for the 8s and 6x9s and leave the others on the hu if they are just woofers.

If you want/need the cap, it goes before the amp and acts as a energy regulator to the amp, providing constant power for it, which prevents sudden draws from your electric system (i.e. headlights dim with bass lines).

The power block comes in with multiple amps. You generally will need a larger gauge wire, like 4, if running multiple amps, then distribute the power locally to them with 8ga. Ideally you will do the same in reverse to ground them, but they can be locally grounded with 8ga and work just fine. Never connect the neg of an amp to the battery, at least without a fusable link anyhow.

Alright, here's how I would do it. If your deck only has one set of preouts, they should be selectable for either front/rear or sub; you can probably change it in the menu of the deck. I would set this for subwoofer and connect it in the rear input of the 4-channel amp. Make sure the low-pass filter is turned on and set it around 120 hertz - you will run the 8" subs with these two channels. Then, get a line output converter and a second set of RCA cables from your local car audio shop. Wire the line output converter into the rear channels of the deck's amp, connect the RCA's into this, and the other end into the front input of the 4-channel amp. Set the front for a highpass filter at around 100-120 hertz, and use these channels to run the 6x9 speakers. Connect the 4x6's and the 4" speakers to the deck's built in amp, and you should be good to go. You may want to invest in some bass blockers for the 4x6's and the 4's; you can get these at car audio shops too.

The capacitor should be installed in series with the thick power and ground connections at the amp - as close to the amp as possible. Run the main power wire from the battery to the capacitor's positive terminal, then run a wire from the cap's positive to the amp's positive. Find a good grounding point, and terminate the ground, run it to the cap's negative lead, then run another cable from the cap's negative to the amp's negative. If it's a brand new capacitor, it should have come with a little resistor or chip for charging - you get a big surge of power if the cap isn't charged before it connects into the vehicle.
