Help Me Finish My Stereo Install. Please?

[NotColtonOrr]

Wiring up the head unit was easy. But I'm having trouble understanding what arrangement the wiring should be in in order for the amp to power my sub. I know I could just take it to a car audio shop and have it done but I don't roll that way. I'd rather learn/be taught to do it myself. So here's the specs for everything..

Pioneer DEH-6300UB

RMS POWER OUTPUT: 14 Watts
PEAK OUTPUT: 50 Watts
PREAMP OUTPUT: 4 Channel
RMS POWER BANDWIDTH: 20-20kHz

MB Quart Onx 4.60 *** X 2 ****

OUTPUT POWER RATING
4-OHMS: 60x4
2-OHMS:120x4
MONO BRIDGE AT 4-OHMS: 240x2

Infinity Reference 1062w

DUAL VOICE COIL
IMPEDANCE: 4-OHMS
RMS POWER RANGE: 100-275 Watts

One amp will power the 4 speakers while the other amp will be bridged and power the sub.

I'm assuming I will need 1 or 2 rca y-adapters but do I need 1 male/2 female or vice versa?

I'm pretty sure this setup should work because Luke recommended it about a year ago and i'm just finally getting to the installation. I know I might be asking a lot but any help would be greatly appreciated!

Outputs: 4-channel preamp outputs (2.2-volt front, rear/subwoofer).

Run 2 pairs of RCA cables from the deck to your amps. One pair into your sub amp, one pair into your speaker amp. On the speaker amp (bold is your case):

"MODE: “2” indicates one set of RCA’s are being used. This will also pass signal to channels 3/4 through 1/2 inputs.
“3” indicates bridging channels 3/4 while running 1/2 in stereo. “4” indicates connecting 2 sets of RCA’s to 1/2 and
3/4 inputs"

No splitters needed.

Hey thanks for your help! I think I understand now what needs to be done. I'll give it a try sometime this week and hopefully it'll all go well.

[NotColtonOrr]

I'm still confused as to how the sub should be wired. Are either of these correct?

The first picture is how you want to wire it on the sub side, assuming the amp can handle a 2 ohm load when it's being run in bridged mode. Pics of this are in my build thread.

To wire a 4.60 (or any other 4 channel amp) to a DVC sub, you will want to run it as if if were 2, 2 channel amps.

Use 1+2 bridged for one coil and 3+4 for the other coil.


Here is something I was trying to explain before though: you need to make sure the 2 pairs are just about perfectly matched in gain settings.

To do this, tune your radio to a pure staic station (as in between stations, just noise) and set your multi meter to AC Volts. Adjust the gains so that 1+2 and 3+4 are identical.

Definitely would not have figured that out on my own. Thanks Luke! I'll finish installing everything tomorrow and report back.

x2 thats the only way to do it with a 4 channel amp

Kick its ass, bud! Oddly enough, I suggest you NOT Use the "2 channel" input mode. That works great if you are using a 4 channel as a 2 channel for a pair of woofers, or mids and highs, but I do NOT recommend it for a single DVC install. I prefer to see the L+R signal mixed before amplification rather than at the woofer.

The only way to achieve that is with Y cords.

You want to feed both left and right into each pair of channels, and leave it in 4 channel mode. Meaning L into 1/3, R into 2/4

Keep this in mind: that "mode" switch does NOT change output wiring or power. It is simply a set of built in Y cords. You cannot make 2 mono channels by using that switch.

The only thing is that they are wrong for this. These mix 1+2 and 3+4. As I said, they are great for some stuff, but not running a DVC woofer. So you do get the joy of using Y cords at the amp.

BTW, This is how I did James Crivellones car, the white MTech1 with the pair of ADS PQ20s and an Exile XP12D and the very first "V2" 12" box.

You are in good company!

Oh, before I forget...Your 6300UB has 3 pair of preouts, correct? Well, seems when you and I talked, you were gonna do ONE of those amps on a SVC woofer (bass and front on amp, deck power on rear) OR a 5 channel on a DVC. Somehow, we got de-synced. The good news is what you did will give you quite a bit more power than most 5th channels.

Either way, you need to run 3 sets (6 channels) of RCAs

So now go kicks its ass!

The headunit only has 2 pairs of preouts. One is labeled as a rear/subwoofer output and the other as front output. I'm assuming this is only gonna complicate things even more haha.

Well, yes and no. If you want to do it really well, get a 2/3 way electronic crossover such as the Planet Audio EC20B: https://www.google.com/shopping/prod...ed=0CFAQ8wIwAA

First, change your deck so the pre-outs are front/rear instead of front/sub.

That crossover will also give you plenty of gain, it will allow you much better signal to drive the amps.

Second option is as above, run all 4 channels off of the front outputs and the sub off the other.

So you're saying that there should be a setting in which i can switch between rear and sub creating front/rear? Or that I should just look for a new headunit with front/rear instead?

I'm sure I could figure out how to properly work a crossover eventually but as of right now I feel like it will only complicate things even more for myself. Especially since I have no clue how to tune everything effectively.

I'm contemplating the idea of just switching to a single 5 channel amp instead. I saw the one you posted up for $109 and it looks like a good solution for now. At least until I learn more and move out of this car audio noob stage that i'm currently in haha.

Btw, thanks for all your help so far. I'm sure you've had millions of questions similar to this and it gets tiring repeating yourself, but it is truly appreciated!

Yeah, you have to power the deck up and go into the initial settings, the sub output can be changed to rear.
