I'm trying to install a new head unit into my 92 GTST, I got the until in but I'm not getting anything from the speakers, I'm pretty sure I have it hooked up right but I read somewhere that the amp in the boot wont operate with a new head unit. I'm trying to avoid rewiring all of the speakers but I'm pretty new to the audio world and any help would be much appreciated.

Sorry to hear you're having troubles.

We're probably going to need more to go on than what you have here. A couple of pics and a hand drwwn diagram would be awesome and also the make and model of your amp and head unit.

Are you getting power to both the amp and head unit right now? And if so what voltages do you see?

I have power at the head, unsure about the amp I will check it when I get home from my little trip. I have 12 volts and a 5v reference at the head. This is the reference I used to write the head unit. It's a lower model kenwood head unit. Not sure of the particular model right now. I ran into this issue then had to leave for a small work trip.

There are wires that run from the console back to the amp. These can be made to connect to speakers instead.

But FWIW, just get the seats out of the car and put some new speaker cable in.

The stock working doesnt look too good I agree, but I'd  rather do that during winter when I dont want to drive this car. Right now I just want some tunes while I'm cruising this season

It's possible the car has the "active speakers" still in the car? Then an aftermarket headunit wouldnt work with the system, since both front speakers and the rear speakers are controlled by individual amps.

The front speakers were an easy replacement, the rear amp can be bypassed pretty easily as well

Yes it does have active speakers! How do I bypass those amps properly?

The front speakers should be pretty straight forward the rear takes some cutting and splicing. I'm trying to find the guide I used to bypass the rear amp that runs both rear speakers.

Found the guide I used.

 

I used crimable caps to seal the wires together, left the rest of the plug intact so that I wouldnt have any potential crossed wires. Works fantastically.

I'm running 4x6 in the front and 9" in the back. They're just cheap Dual speakers (cheap American brand) but they sound fantastic compared to the originals whose membrane had disintegrated like 10 years ago haha

saudering iron

Now, it's one thing for you Yanks to say "soddering iron" (when it is spelt soldering, and said with the L pronounced like in the word "older", by the original architects of the language, and us Aussies), but it is another thing entirely to spell it the way you weirdos say it! Did you make up the spelling "sauder", or is that actually how some/all of you write it also? If so, where the hell did it come from?

      Another little story of weird shit happening

      By GTSBoy · Posted

      I'm thinking that this is such a small part of the problem that you could easily forego the vac pump and just achieve 90% of what you need, which is keeping the gate open when off boost. It's not as if there are not already techniques to keep a gate fully closed under boost. After all, you have boost. Just use a wastegate actuator that will allow you to apply the boost on the appropriate side, just like every external gate out there.

      Heres another fitment photo. redrilled the pattern to 5x112, and threw my audi´s rims on. had to touch the upper control arms with grinder, because the "sharp corner" was sticking about 2-3mm on the tire path. i have the "fender lip" mostly cut off, otherwise these (too) would contact with it. 20x9.5 ET25 rear    265/30 20x8.5 ET20 front    255/30 they are temporary, and look too big for the chassis. searching for 19s to it.

      Background: my BMW 225i hatchback (rebodied MINI/X1) came with 3x RE003 and 1x Goodyear Asymmetric something. The RE003 roared and slid around, the Goodyear side was quiet and grippy. Definitely my car was thrashed before it got sent to dealers. My brother also got RE003 all round on his old VA WRX STI, I wasn't impressed with them, car was loud so can't comment on noise. Anyway, Hankook stopped making/updating V12 Evo2. So bought S1 Evo3 runflats. Great daily duties tyre and not that harsh ride. Tyre reviews site/youtube rated them as best stopping in the rain and I believe them. Next set, Goodyear Asymmetric 5 non-RFT. It beat PS4 in tests and is like $100 cheaper, so put them on. Great tyre, more grip then S1 Evo3 but a tad noisier as expected, still rocking them. Next set I am looking to go runflats, probably the new Hankook Evo. Although the new Pirelli PZ5 did well in tyrereviews test. Or go Goodyear Asymmetric 6 which was top tyre last year. The V12 Evo2 on my gen5 Liberty GT wagon did great in cold condition (drove to snowy mountains for a day so my husky can feel his ancestor's roots). Super impressive performance for $120 each lol. Never skimp on tyres, brakes, suspension. There's old pics of my R31's crappy random brake pads bending in the caliper at Oran Park track day somewhere around here. Anyway, my 2 cents.
