Is it a bad idea to connect the amp to the system without the sub connected?

..because I did it, and I got the same problem. The only wires in were power, ground and remote. The amp would hardly be drawing anything in this state, right?

If everything is normal, then yes. If something is wrong with the amp, it can be drawing for no reason.

not amp, per se, this happens when you are drawing more power than your alternator/power can provide without pulling from other areas, if it bothers you, add another battery and a higher output alternator
My problem wasnt as bad as this but instead of a bigger battery/ Alternator. Put a capacitor or maybe 2 in and it shoudl fix your problem. I got a capacitor for $15 at Frys and that solved my problem. The following are things I have connected to my battery. Radar detector, GPS, speaker amp, subwoofer and subwoofer amp, and sometimes charge my phone at the same time. The capacitor fixed the problem easy.

No. The correct response is not "Add a capacitor". The correct action is what DFW did: "Upgrade your alternator and/or battery".


ETA: In response to the OP's problem, it's most likely a bad ground. The old amp might not have pulled enough current draw to make the lights flicker/engine stumble. Improve your ground and look into upgrading your battery.

Or simply add a capacitor and save your money.

No. Capacitors are bandaids that don't really work. You're still way overstressing your electrical system and sooner, rather than later, you will have to replace your battery anyway.

Besides, any quality Cap is going to run close to what an upgraded battery will run ($75 compared to $100)


Thus, the correct response remains: upgrade your battery and/or alternator.

...that's probably going to cause more problems down the line.

But, hey, not like I'd know anything about that.
