Couple quick Audio questions

[2500 Gasser]

Hey guys, just picked up a 21' 2500 HD custom (gas) non Bose.  Purchased Infinity Kappa tweets, 6x9's and 6.5's and will power them and my kicker sub with an Alpine 5 channel.  My questions are as follow.

1) will I need one of the LOC's I'm hearing about in the threads, or does my head unit have RCA outputs for my amp?

2) If so, what is recommended? I've read a little on LLJ , and PAC make em I believe?

3) This may sound ignorant, but will a 5 channel power my 6 speaker plus a sub setup? Not sure if I can count the crossover feeding my tweets and 6x9's as just 1 channel. 

I've searched threads and YouTube looking into 2500 HD's only, but are all Silverados the same, there seems to be more search options if I include 1500's.

Any and all feedback is welcome and appreciated! Cheers

You will need a LOC unless your amp is capable of taking speaker level input vs RCA.  The LOC will give you control for getting it dialed in as well versus just having raw signal (good or bad).  

 

My installer had me purchase the T Harness from LLJ (still waiting to receive it at this point) as nothing else was available to him currently. Metra, PAC, etc either didn't have anything he could find or there was nothing available to order.

 

He could cut and solder but the harness will make it neater, faster, and easier. 

Rockford 5 channel amp I use to power focal rear doors, focal front speakers (separate with crossover) and kicker sub:

Good luck and enjoy your much better sound when you are done.

Thanks Knight. I've heard the lead time from LLJ could be a while, I may just order it now. I do appreciate the feedback, and know 5 channel will work as well

I see several harness available at LLJ, can anybody tell me the specific one I'll need for a 7" non Bose. Will I need the fullamo kit setup, or do I just call them and ask?

I'm assuming the screen size doesn't matter from when I was poking around their site.  More Bose/non Bose and need to know your connector colors above kick panel behind the glove box (black/gray or aqua/tan). 

T-harness lets you run your wire from amp to speakers however you wish to do so.  Their loop back supposedly returns the wire from your amp back to the factory harness location to use factory speaker wiring from what I understand.
 

But by all means shoot them an email.  Very friendly.  It did take a full day+ for them to answer me though.  I take it they are pretty busy.

Are you guys with door speaker upgrades running new wire to them, or sending amplified signal through OEM speaker wires?

I'll be running 75 watts rms 4ohm.. Just want to know if it's best to go up a gauge or two on the connections
