So here is my setup B18B turbo tuned on hondata s300. So a couple of days ago I had my sub's and box installed in my car. On my way home driving 65 on the highway my car would seem to lose power, I would have my foot still on the throttle pressing down but the rpm's would start to drop until I got to 1000 rpms then would go back up to about 5000 then do it again. I always fill up at the same gas station and have had the same gas in the car for the past week so I don't think it's the fuel. I had new spark plugs put in back in July when we did the setup. Any ideas?

Thank you.

well id say maby the altonator is wanked or els the subs are draning two much power. see if it hapens again with the subs on it will probly happen when you turn on your lights aswel. if thats the case i would try fitting a bigger battery. and if that dosent fix it maby a new altonator. i hope this helps
