Trying to install subwoofers into my car
 

Hello everyone,

I drive a 2005 Honda Accord EX Coupe with a navigation head unit and I am trying to install subwoofers into my car. Every site I go to tells me that they are not compatible with my car. I dont know much about subwoofers but maybe you guys could help me out because I dont have time to go into bestbuy and listen to some guy give me the wrong information. If you guys could help steer me into the right direction that would be cool. Thanks

subs are compatible with your car.

you will either need an Line Out converter (LOC) or you will need an amp that has a high level input.

Then you will need:
an amp kit
sub(s)
a box.

if you go the loc you can splice into the the speaker out puts and run rca's to the amp. if you go high level you will need the correct wiring harness to plug into your amp. then run a + from the battery to the + on your amp (fused). then run a ground from the amp to the floor of your trunk.be sure and strip all paint from your ground spot. careful not to puncture the gas tank. run a remote from behind the head unit. wires from amp to subs in box. there you go you have subs in your car.

that was a very simplified answer to your question. If you have a more detailed question I (or someone else) will give you a more detailed answer. but the simple answer is yes you can put a sub in any car and it is fairly easy to get them in there.

also you will want to take note of this thread:

If you haven't bought the amp yet, I recommend an amp with high level inputs and auto turn-on. Simplifies everything.
Kicker, Phoenix Gold, JL Audio have amps with those features.

While connecting to the rear speaker wires will seem the easiest, I strongly recommend connecting to the front speaker wires behind the factory radio. This way you can use your fader to attenuate the factory rear speakers. While you are behind the head unit. You could install bass blockers for the front speakers, which will increase their clarity and power handling. Bass blockers are inexpensive in-line capacitors that provide a high pass filter with 6 dB/octave slope. 120Hz bass blockers would be a nice choice.

Running and connecting the power and ground wires is important. A lot of people do this poorly and create a hazardous situation. We can help you through that if you are patient and want to do the job right.

The power wire connects to the battery and has an inline fuse within 12". It is protected with split loom and routes to the firewall. Above the gas pedal, behind the factory sound insulation barrier, you will find a grommet through the firewall. When routing power wire through the firewall, you need a grommet to protect the wire. Once through, the power wire routes down the drivers side, in the corner of the floor, under the carpet. I find it is much easier to do this with the drivers seat removed. the power wire routes to the trunk. You can follow factory wiring up and through the factory opening on the far side of the rear deck.

While the seat is out, run to pairs of speaker wires down the center of the car, these are for connecting the front speaker output to the amp.
