    Now I decided to buy 150W opus.

    i have other question to you about upus.
    whitch version is better?
    the build in one or just pcb?

    I use hight-green black case for Epia M with slim dvd and full size hdd and there is av very small margins to put opus in there but I think it schould go.

    someone who has high green case and mouned inn opus? 55W is not som mutch so I don't think so that opus will go to warm in that case. for other site, there is alwas possibility to modify a case.

    Hi Goose,
    I don't have the problem of it dimming in my Celica (190/GTS/T-Sport depending on where you come from)

    I am running it on a Stock Toyota Celica battery and use the lilliput cigarette charger cable.

    What might be helping (although indirectly) is that the audio-video install I have has a 1F capacitor. Its hooked into the power distribution block on the boot which happens to provide all the DC power for the amp, CCFL lighting and 300w Invertor that the PC is powered from. Might well be smoothing out the power drain.

    BTW - In the UK the 190/GTS is known to have an ECU problem that is seen as the lights dimming and/or the whole car momentarily cutting out. Its not just a UK thing though as the batch affected has a certain VIN range

    NJay, ys I have today sended order to new Audio amp and Subwoofer, leater I will change all speakers in the car and buy one more audio amp.
    I am goying to put a 1 farad capacitor, but I nned to chenge my battery, taday I the car started on the las try before battery was empty and it was jus -1 C outside.
    So i think I will salve some of the problem with new battery.

    BTW. In norway the Celica is called Celica and Celica T-Sport, but I mean that US name is better GT and GTS...

    Ow just for a informng you and those who are interested. I found a tuning werksted in Polang that will make my GT to ZGT reasure turbo the result is 196 HP @ 260Nm)
    that schould be inuff for an GT engine...
    *** lots of projects ine my mind but less money ***

    Going way off topic.

    Founder member of Celica-club has tuning compnay. His own 140 is currently running a direct-port nitroused, Supercharged setup. Its has been going strong for well over 6months (he races it on tracks) and let just say its putting out more than that and that's at the wheels not at the crank

    nJay, I have'n say that ZGT will be fastes, but with my setup i will not destroy my engine at eny point,
    More power same toyotaengine quality.
    It is not a problem to get 270Hp fro a GT engine, but I am going to put onlky a turbo without any other engine changes.
    196HP is just inuff to kip a engine running quality.

    Your problem sounds like voltage drop pure and simple you need more, I suggest you have a electrical wizard like the guy at Waltz in Salem oregon rebuild your alt, he got 135Amps out of a small case Chevy alt for my truck and 244 out of a large case for my Surburban.

    in a nut shell when you kick on the hi-beams or hit your brakes hard enough to engege abs you are pulling more juice then your alt can make so the voltage drops for a second or two. a bigger would help but you can't fill a 55 gallon buckey with a spray bottle and a 80 amp alt is mighty small for running a stereo, fog lights and all the other bells you might want to add.

    the same is when brake hard so the ABS system turns on.

    Now I know my car battery is old now (3,5 years) and have to be changed, but will new battery solve the problem?

    Or maby I have to mout a condensator 8or what it is colled in english ) to get stable voltage and amp?

    or do I have to go for 2 battery system? (the seccond one takes chargin but is not giving amp to the rest of the car.)

    Or is it something else I can do?

    My Car alternator is 80A...

    here is schematics over my system:
