Hello cruzers,new member here, just wanted to let everyone one know it鈥檚 pretty easy to upgrade the audio in the Santa Cruz. I replaced all the speakers and added a 4 channel amplifier. I didn鈥檛 take out the factory head unit, all signal wires were located in the kickpanels ( I am using amp with high level inputs). The sound is like night and day from the underpowered factory system. I鈥檝e been in the car audio field for 25+ years and have plenty of experience. If anyone needs any help upgrading their factory system, I鈥檓 here to help! BTW this was done in the non Bose SEL vehicle.

Where did you place your amp?

With speaker replacement, I'm guessing you used component fronts. Did you use the crossover that came with them or did you use what I assume is a factory crossover? Did you just glue the tweeters in?

Amp is under the drivers seat, I鈥檓 using coaxials in the lower doors and separate tweets in factory pod, using PAC bass blockers in line for the tweets. I used a backstrap to make a mount to hold tweets using factory screws no hot glue.

Since I understood none of that, I'm going to take it that what's easy for you and other people is going to be very hard for me. Which speakers did you replace them with?

I had some Memphis PR鈥檚 6.5 coaxials laying around, the factory speakers r 6 3/4鈥 so I had to use a spacer bracket. I know everyone is not an installer, but I can answer any questions u might have on upgrading speakers or whatnot.

Do you have any pics?

Were the wires in the front kick panels for the front and rear speakers?

I didn鈥檛 take any pics, and yes the right side speakers r in the right kick, left side speakers r in the left kick. If u need wire colors I have them.

Gotcha. That's very helpful information. This might be a summer project for me. I'm going to try and find a harness that lets me splice in without cutting factory wires first.

Yes - please post the colors of the wires!

What amp did you use? I was thinking about using the Alpine KTP-445U, as I used it in past vehicles with good results. Its not a huge amount of power, but it does have crossover and gain adjustments.

Also, do you know if there is a center channel in the non-Bose? It really sounds like there is a solid center stage and there are mids that I'm sure are not coming from the puny tweeters.

The amp I am using is the Infinity Primus 6004a. Yes I know about the center speaker in the dash, I鈥檓 gonna leave in running off head unit power. Speaker wiring attached.
Was the Infinity amp and plug-n-play replacement of the factory amp? Or did you need to get special harnesses or splice wires? Were you able to use the factory amp power wire or did you have to run a new one?

I'm looking for a plug n play solution so I can leverage the factory wiring and not have to run cable or splice wires.

I did not have the factory amp, there is no special harness. I had to run 2 pair of wires to each speaker wire location, which I found to be most convenient and accessible in the kick panels. I ran a total of 8 pairs of wire ( 1 pair to get signal to the amp, then from the amp back to kick panel). There is no plug and play, you are going to have to cut and splice wire, there鈥檚 nothing to it and is totally reversible. And yes I had to run a new power wire to the battery. If you don鈥檛 feel comfortable doing it and decide to take it to a shop to have it done, they will do it like I did.

Pictures with a write up would be greatly appreciated. I have been planning this out for a couple weeks, but new cars are way different from the stuff I used to play with in the 90's.... :D and the non Bose systems needs a lot of help. Would love to see how and where you tapped the existing wires from source to amp and back to the speakers?

Do you also happen to know if we can tap existing wires for the BOSE sub under the back seat in a non Bose system? Does anyone know if they ran the wires for the sub anyway? If so do you happen to have this pin out? If not, what would you recommend tapping into for high levels for powered sub, in addition to an amp for fronts and back..... Thank you in advance for any help and guidance.

Pull the kick panel on either side there will be several white molex connectors, the speaker wires r twisted and the colors r listed above in the attachment. Cut rhe speaker wire according to the color noted, make sure u leave enough room to attach new wires, ie don鈥檛 cut the wires too close to the connector or too high on the harness. The output from the radio comes down from the top of harness and the signal to the speaker goes into the molex. Cut that pair in the middle so u have room to splice. The speaker wires r bigger than some of the other wires in the harness and are twisted. U can be verify u have the right wires by ohming the wires with a multimeter, the factory speakers r 4 ohm, u will get that ohm load at the molex not at the other end of the cut wire, since it goes to the head unit.
As far as adding a sub with the non Blows, I mean Bose system, u will have to tap into a door speaker to get signal. Use 2 speakers to tap into, left and right, not front and rear. That鈥檚 why LOCs have 4 input wires, for 2 speakers, more signal for the amp low level input (RCAs). Hope this helps.

Thank you Ingkel very much. I understand all the basics of the wiring, would love to see your work... ;) I was hoping you had a few pictures to share to save the time of guessing RF+, RF-, LF+, LF-, RR+, RR-, etc........ if not I will default to toning each one out.... Seriously though, Thank you kind sir.....
