HOW-TO: SC300/SC400 Install Aftermarket Head Unit, OEM Speakers and Sub Working!
#407
Hey Raine!
Ok I got all the new wiring done and I have sound out of all the speakers in the car the only thing now is my amp is not turning on to power my aftermarket sub??? I have connected the power source to the battery for the amp, connected a ground wire, connected my RCA cables and remote cable but still no power light on my amp =( I did test it out when I first bought the amp to make sure it powers on and it did but now I have nothing =( I do not want to put everything back together until this is solved. Any info on this matter? All the fuses appear to be good. I am running some 8 guage wire to connect the sub to the amp. I just dont have power to my amp now which is a little confusing

...wait - there's something missing in your description - what about the amp turn-on wire?

I feel like this is an extremely dumb question....
But I want to make sure I do this right
So you have to run 4 sets of speaker wire to the trunk PLUS the amp turn on wire, correct?
So you'll need 5 sets of wires running back there in total?

Ya I have the amp powered by the battery, the ground is connected to a bare piece of metal in the trunk, and now I have to reconnect the amp control wire. There is no (turn on wire) it appears.

Any one know what the stock amp puts out in the sc300 I currently just put two twelves in and im thinking of a 10 for the factory slot and as far as this post goes run your power wire next to your remote wire (turnon wire) and your RCA's which should only be two unless your running two amps like I plan to do or you are working with factory head unit but anyways the reason I say run them separate is because depending on your amp/setup you will get a whine threw you speakers some times it differs but anyways that is caused by the power wire being close to a negative (RCA speaker cable) so run them separate hope this is helpful to anyone

FYI try reading the HT again. It's punctuated, should be easy. You'll see that there are no line-level RCA cables at all running next to power wires to the trunk. The only instance of an RCA is between the sub-out on the aftermarket head unit and the OEM sun wiring behind it. The wires running to the trunk next to the remote turn-on wire are already amplified by the aftermarket head unit. So no whine at all THROUGH any speakers.
If you're running two aftermarket 12's and "plan to" run two or more aftermarket amps, then you're far from what this HT is for. And running a 10" in the rear deck off the OEM sub amp is pointless if you already have a pair of aftermarket 12's in the trunk; first of all, the OEM sub amp only pushes out about 30 watts at 1-ohm; second, leaving the OEM sub out when you have trunk-mounted subs allows the bass to get into the cabin, by way of passing up and over the fuel tank and through the OEM sub hole in the rear deck.

Raine,
Long time lurker first time poster here! I just wanted to drop by and thank you for a well written and informative DIY! I just finished dropping in a Pioneer AVH-P3400BT and used all your advice (even down to the Epicenter, which ROCKS BTW!) and everything (and by everything I mean sub amp and antenna) works PURR-fectly!! I also used your write up on the Metra double din mod to put it in the dash. I also added a XM module to the setup which is co-located with the Epicenter where the OEM main amp used to sit.
By the way, this was in my 98 SC400.
Thank you again!

By the way, a note to Nakamichi peeps - I'm working on getting the wiring worked out with the help of RealSC400, hopefully I'll have a solution soon

I have a 95 SC3 with the NAK system and with the package tray removed, and the Nak system removed as well as the trim in the trunk removed and rear seats removed. If you need pictures to help do a write up on how to wire the Nak system up to a double din touch screen, im more than welcome to help u with that. I have plenty of wiring equipment to make it look how it should. I have plenty of heat shrink, t-taps and i have spools of wire that I had from Harbor Freight along with all kinds of other stuff including a test light and multimeter.

Thats the wire kit.
Lets do this so I can have a radio in my car lol. Just let me know what you need. Everything is all factory and present. Only thing that has been done is I fixed all the broken wires that were cut by previous owner and rewired everything back to its factory locations.
