Hey guys, so i've got a r34 GTT. and with the help of this forum a few months ago i installed and tuned it. Pretty much my "system" is:

4 speakers - 2 front 2 rear

1 sub woofer

1 1200 W Amp - 4 channel

1 Head deck

.

I have amped the two front speakers to the amplifier's front ports

And i have amped the subwoofer to the amplifiers rear ports bridged.

the two rear speakers are connected to the head deck still.

On the head deck i have all bass settings set to as minus as they can get (to avoid the front speakers distorting from bass)

The amp has the gain for bass set at about 3/4 and for the front speakers at half way.

The issue is, I have bass when the system is turned up really loud, however, at lower or normal volumes there is no bass at all. I can tell the front speakers are trying to make a bass sound but dont. and the sub is pretty much not putting any bass through.

Any help would be appreciated, thanks heaps.

boss amplifier 4500 ( i know not a good brand)

bass boosted songs play great, however normal ones dont.

polarity is correct, and im in westmead. (NSW)

Why don't you set the bass setting on the head unit to 0 and then set the gain on the amp accordingly?

Turn off all bass boost options (including loud). On the amp, set HPF for the front channel, set LPF for the rear channel. If you have the option of setting your rears as sub on your head unit, do it. Crank it up and tune accordingly (close all your doors/windows lol).

    • @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand
    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
