guys! voltage stabilizer is not something on which all the performance depends,all the friends here are almost facing the same problem no matter its mehran or civic.leme try explaining a bit again.
The car being stock or equiped with heavy sound system becomes weak after some good usage a stock car becomes weak a bit late then that using neons,hids,sound system,leds,flashers etc etc & a heavy sound system shuts off cz it uses extra voltage for low and mid base levels etc and when there is a voltage drain on one side head light,tail lights etc start getting weak or u see dimps in it.when the system becomes very weak then u start seeing the things like sound system turning off or restarting or amps tripping in a last stage scenerio lights going dim and when u leave the gas pedal battery light comming up.now voltage stabelizer is not only the solution it could be the last resort.firstly u guys need to get ur generators(alternaters),coils,ground wiring check.old wires develop resistance and increase the blockage for the current flow resultingly ur electric systems get laid down.so change the ground wires if needed.then comes the voltage stabelizer along with the high flow grounding kit preferabely the HKS grounding kit which has (HKS) engraved in the wire its the best for enhancing performance along with the voltage stabelizer.this setup will give brighter headlights,a heavy base and a better acceleration.cz heavy acceleration also takes ur current,i hope this helps a bit.
Pivot stabelizer the original one comes at least for 6k the b class product would give u the performance but only for a couple of weeks and again slowly ur car would fall back to its current position so if u want some performance spend some money once and get the real product...
