Not enough battery power?

[fuji]

One thing that may help is "the big 3". This is a mod which is very popular on other car audio forums. If you google it there are several tutorials. The bottom line is it greatly improves your grounding system. If your gounding system is a bottleneck, your system does not sound its best. Some also claim it takes away some of the stress on the overall electrical system.

If you look at the wire that connects the chassis to the negative terminal of the battery it is very small. I only upgraded the ground wire from the negative terminal to the chassis and the throttle response improved.

If you just want to do the "Big 1", get approx a 6-8" run of flexible 4 gauge or 0 gauge power cable(get it from www.knukonceptz.com). Make sure it is nice and flexible. Get two ring terminals(Again from Knu) that use little allen screws to tighten them down. This way you can adjust if it is too short or long. Do not remove the stock wire, just add the additional grounding wire to the stock location. Another thing you may want to consider is some light sanding of the chassis where the ground wire connects. There is paint and you should be in contact with the metal itself.

Fantastic idea, thank you. I will do that. Just add a few more 4 or 2 gauge cables to the grounding system. Thank you very much.

My lights still dim just a little bit sometimes... The water line is on the right side of the fire wall... I think that is where I pushed my power wire through. I used the stock speaker wires. Cut them behind the radio, added speaker wire to and from the amp and back to that same spot. I think it would be an unnecessary pain to try to run new wires through the doors. Go check crutchfield for fitting on the speakers. Good luck with your install man! And welcome to YARISWORLD!

Thanks for that. I realised that there is a space under teh rear seat, is that where you have your amp placed?

Thanks for the warm welcome. I will post up photos of the install once i take delivery of the car. I am just acquiring my audio gear now.

I got a

-alpine CDA-9886 head unit
-eaudio 480ab 4 channel amp (no rear speaker, but 200+ RMS / channel bridged)
-Sub still looking. Looking for a SQ sub.
-Components still looking.. any suggestions? I heard the focal 165 krx2's and they sound very nice.

I live in Japan, and I usually buy off Ebay or Amazon as its cheaper, than locally. Anybody here know where else I can buy speakers? There isn't much Rainbow, Focal stuff on Ebay that will ship to Japan for a reasonable amount.

Thanks guys!

I think the below might be better than an ebay grounding kit. I will probably due this instead.

I am trying to stay away from installing a new amp. I was really hoping to run what I have off the stock electrical system. I will give it a go, if I can't, will need to get a Yellow top.
