Yeah, I'm using the stock amp.

how many watts is the aftermarket sub and stock amp ?

I am not too familiar with electronics... but would there be any risk of damage to the stock wiring caused by hooking it to a larger sub???

no...... the only issue you might run into it underpowering the sub, wich can be just as bad as overpowering it. Overpowering the sub will cause too much power to go to the sub, making it burn up its coils, under-powering the sub can cause clipping in the amp (b/c the amp is not powerfull enough to power the sub right so you have to run it a little louder to get the same amount of bass out of it), a clipping amp can send distorted signals to the sub causing the sub to also blow. The best thing to do is to get a sub that it rated close to what the amp can put out at the right ohms. The local car audio shop told me that the civics amps/subs use a non-standard ohm setting to get the stock sub to sound better at lower power.

this is awesome, i really want to do this. so after having this done for a few days, have you noticed any abnormalities, like extra heat coming from anywhere or a bad sounding set up?

[WHITEcoat]

I was told that you would get more bass if the subs are facing outward, toward the trunk. Would I get more bass if I turned my subs in the same direction you have?

Hmm, I have a 12 at home I think I will try this

Nope, not a problem yet. I'll let you know if anything funny goes on.

Did you have the sub level turned all the way up and did you make sure the wires were connecting? What type of sub? Did you make sure you had the wires from the speaker connection to the sub wired properly? What type of music did you test it with CD Radio MP3? bass level? If you tried all that, and it still didn't work then the amp may not have enough power to to push the 500rms that your comp ten is rated at. The sony that im using is rated at 380rms.

[SoCal07Si]

Sub was all the way up, bass too. Wires were connected, i reversed them to make sure, still too weak. Its a RF dvc competition 10". 500 w RMS. Tested it with the radio, then a CD.

My friend gave me a sub. It's called the "Earthquake" And there's one sub on each side of a black enclosed round enclosure. It says 800 watt on the bottom of it, doesn't specify rms or not. Would this be safe to use?

I think it might rattle the trunk. That is why I have it facing the way it is. Also the sub is protected from crap in my trunk with it facing the seats.

Oo my question next!

Haven't a clue.

[Si Speed 317]

Solid answer. Any one else chime in?

Also, brennon, that adapter in which you put the wires into is located where in the stock setup?

If you pop the trunk it is attached to the sub on the right side of the sub. it is pretty easy to find since the sub in centered in the trunk.

Remember bass is NOT directional, BUT with that being said, you can put you sub in one spot and it sound ok, then move it back a few inches and it sound 30x louder. Take this from someone who installs/designs BIG dance club sound systems. if the your trunk is going to rattle, it will do it no matter what way you face it, but you better watch how close you put it to the back of the seat b/c the speaker might be hitting the back of the seat when its working, wich then yes, its not going to rattle the trunk b/c the seat if causing it to not make as much sound.
