2013 touch screen HU and alpine power pack

I just bought a 2013 texas edition today(yay for stickers and emblems ha) it has the factory touch screen with USB/AUX and Bluetooth. I have no reason to replace it since it does everything i want, minus the power output.

I have an Alpine Power pack mini amplifier from a previous truck and figure since my budget will not allow for the system id like, i might as well be reasonable with myself and goals and use this amp.

I do not want to cut the factory harness, so could i use the metra part number 71-1761

$10 Reverse Wiring Harness for 1987-2007 Toyota Lexus Scion Vehicles OEM Radio (71-1761)

to plug into the headunit, then connect speaker wire to RCA cables http://www.crutchfield.com/p_136XDCLR2S/JL-Audio-XD-CLRAIC2-SW.html?tp=1222

connect to power pack (select speaker wire input on amp)

then connect the output wires to the metra 70-1761 http://www.crutchfield.com/p_120701...r-Wiring-Harness.html?search=70-1761&skipvs=T

to the factory harness?

i know its a round about way to do it but it keeps me from having to cut the factory harness.

set the HPF at 60hz and adjust sensitivity accordingly?

reason being is i have the RCA's, the Amp, and would only need $30 worth of harnesses to complete the install.

eventually at a later date i would replace the door speakers and sound deaden the doors, but id really like to keep the factory headunit as i have no need to replace it.

 

well i ordered the above parts, got everything installed today. WOW, just a small jump in power resulted in outstanding gains. i put the fronts on a 120hz HPF and the rear at 80hz HPF. Definately need sound deadening for the doors which i will add RAAM audio deadening and ensolite later on after this coming winter.

i have the gain set very low as the factory speakers cannot take too much power without distortion but the results are great.

I do have some a Alpine type-s tweeters from a while back when a customer gave them to me, and those are rated at 1100hz-22k hz so i will probably swap those in the front doors for a better mid/high.

while doing the install i also tapped in an extra set of speaker wire to RCA adapters for a subwoofer later down the road. i will just need to find an amp that works with high level inputs and ill be in business.

 

Perfect, I've been trying to figure out what harness, reverse harness works for the 2013 Tacoma with the standard touch screen non JBL. I need to pull high level inputs off of the head unit rear outputs for a small sub and don't want to cut or splice. Thanks for confirming!

 

will this work with a 2015 touch screen/nav non JBL?
