when I was looking into this last year, I ended up talking to a factory assembly line worker on a message board and he told me they do use different harnesses depending upon the options in the truck.

trytokeepup, if you're going to put in aftermarket subs and amps, just run new wires (at the least the main power wire from the battery to the amp).

 

So as far as RCA's and remote wire....how can i avoid tappin into the speaker wire with a line converter since im keeping the factory HU?

If you can walk me through id greatly appreciate it with out running all new wires. Id like to make things simple as possible since im very unknowledgable about this stuff. Thanks again!

 

I have read about your search for the harness...is there anything you can tell me about making my own? I think I read that you went to Radio Shack and had them hardwire your subwoofer in? Anyways, any wire harness info would be greatly appreciated...I have been doing all the searches I can and haven't found an exact answer...I am about to go to the stealership and get their "knowledge" on the matter...Thanks in advance

 

I kept my factory HU and went with an MTX Thunder 251D amp for my MTX sub, it has built-in speaker level inputs. There's no RCA's to use, but you still have to tap into the factory speaker wires. The speaker wires go into the input on the MTX amp, and that provides the signal/sound and automatically turns on amp (no remote turn on wire). I used the rear speaker wires for the amp and I found them in the channel along the driver's side door sill.

To provide power for the amp, I got a 10 gauge amp wiring kit. Came with a red 10 gauge power wire with inline fuse. You just wire that straight from the +positive battery back to the + input on the amp. Then ground the amp with the black 10 gauge wire and you're done.

So to avoid more wiring/line output convertors, find an amp that has speaker level input.

 

No that wasn't me, I went with aftermarket amp/sub instead since I didn't have the plug back there. Member Sandog53 wired up his own plug to get the audiophile sub/amp to work.

If you goto the stealership, stop by the service counter and ask them if you can see their electrical wiring manual for our trucks. and find the section on the audiophile amp/sub. In there, you'll find diagrams and charts with the pin/plug details.

 

Thank you very much!!! That helps out alot. So basically that fancy plug i have in the back doesnt do me any good.

 

You're welcome. Well if you have the plug, you could get the factory audiophile setup if you want to. The sub/amp come's as one unit and you plug that rear "plug" into it. But then you need to get the Audiophile HU and also make sure you have the extra 3rd plug up in the dash to plug into the Audiophile HU.

 

haha, That plug is sacred to some of us....

 

I wonder what it would cost to just get the audiophile sub and amp? Im guessing i can spend that much and get better aftermarket system with 10's and sound much better.

Do you think i could get by using 1 10? I really dont want to have to take the jack out and make a huge box to fit under the seat so i was thinking just going with one sub. Maybe even a 12 if it would fit? Im just looking for extra bass but the more the better. I plan on keeping it pretty simple and cheap.

 

Just did 1-10", box, amp & installed for 375. Sounds better than audiophile too!
