the amp will run you about 12K the sub about 9K so there goes half your budget.

Default How will you connect the HU to the amp??

Hi, i went through your thread.. but as far as i know the stock civic HU unit does not come with RCA outputs. How will you connect the amp to the head unit. If you use the line level input provided on the amp.. i have heard there will be humming from the amp and also the quality will not be good.

hi, my setup is still half done, currently i have a ID12"v.3 sub powered by kenwood 9103d mono amp with audison 4 gauge power wiring. as you all know i have already got the DLS speakers and i am getting the audison LRx4.5 amp by this week. the ICE setup would be complete, but the headlights/tailights dimming problem has still not been solved, after the complete setup, i think it would dim even further. as most of you have suggested that capacitor would not help much. i dont know about changing the BIG 3 wires as my civic is brand new. i am not much concerned about dimming, as it does not bother me. but won't it reduce the battery life and might even spoil the electrical systems of the car. there has to be some way to solve this problem. i am concerned that it would hamper the life of the battery.

@sanchits, you need not worry about the battery or its life. The problem that you are facing has no effect on the battery, nor the other electrical systems.

What is happening is that when the current drawn by your ICE is increasing beyond a point that the alternator regulator can regulate the voltage, the overall system voltage is dropping - and that is reflecting on your head/tail lights dimming. You are seeing the difference between operating at 13.x volts versus 12.x volts.

Quite simply, during music peaks the line voltage is dropping to battery voltage (or slightly lesser). During these peaks, your battery will not charge, but so what - it will charge during non-peak times. The culprit is the alternator / regulator, which is not designed for your level of transients (peak load occurring for short durations), not the standard harness (your amp would not be connected to the standard harness).

You just have to figure out a way of replacing the alternator / regulator without voiding the warranty.

Dimming is there in every car. It depends how hard you are playing your setup. Maybe your amp gains are turned up, Ground is not full tight, Power cable might be loose some place. There are lots place where there can be problem.

Also how much dimming is there it is very high or a little that one also need to see.

the quality may not be as good as it would have been via pre outs but if properly done you should not have any "humming".

Guys, listen if LBM does not find the need for a cap why do all of you worry. LBM's system (from what I hear) draws in excess of 2000W rms (at peaks) from the battery, few systems draw more.

i learnt this from LBM too, just keep your car on when you want to flaunt it.
i always keep the engine running while playing my system.
