530 subwoofers

I want to upgrade my subwoofers in my 04 530i. Just wondering what others have done and what you upgraded to. Should I put a sub box in the trunk or should I try and upgrade the factory subs?

I've been looking at 2 12" subs in the trunk.

i went with a sub box inthe trunk with a ported band pass box, thru the rear arm rest. that way all the sound goes in the cab sounds great.. 2 amps. one 300 amp for mids and highs with the stock speakers. a 500 amp for the woofer... worked well in my car ,,, i didnt go high amps to be easyer on the alternator.

I have a 12" JLW7 sub in the trunk with a custom side molded enclosure with a JL HD 500 amp!! Maybe wayyyy to much base but it sounds incredible.

Leathal,,,, wat is a side molded enclosure ,, different than a woofer box?

Did you connect it to the factory system through any special equipment?

How is the car handling it?

I have the factory speakers hooked up to a 300 watt 4 channel amp, the woofer I got running on a 500 one channel amp, all the connections are tapped into the factory amp harness in the driver side trunk panel , I'm running a 10 inch woofer in a ported bandpass box made out of one inch mdf, the port runs thru the arm rest in the back seat, all the sound goes straight inside the car out of a 4 inch port ,it sounds bad ass,,, no rattling in the trunk it's a solid deep tone,,

Could you post a pic of the port going through the rear seat arm rest? I like your setup but don't want the port to be too obvious.

Thanks

Above it the sub enclosure I am talking about.

Leathal,,,,,,,Very cool enclosure. do u get alot of rattle and vibration from air waves bouncing in the trunk ?. how does it sound inside the car ?

No rattle that I know of, I have a separate control for the sub that I can turn it up or down. It can vibrate you're body its so loud or you can adjust it down so that it just sounds like a rich deep base. The sound quality is just about the best you can get.

Patdougher.... will upload pics soon

l like that it looks clean... how do u power off ur amps..

You don't have to power them off. You just set the adjustments where you like them at the amp and use a separate control mounted somewhere near the dash or center console to turn the sub up or down. No need to get in the trunk.

I see... i have mine set up alitle different.. i have a module hooked up that automatically turns on the amps wen it senses power turned on in the car . like the remote to open the car.. and automatically shuts power off to the amps bout two or thre min after the car is turned off or the car is locked. i also have a switch in the car tha cuts powerr off completely.. to overide the module.

so ur amps are always on?

Patdougher.....the thumb nail is a pic of what the port looks like in the car .

Pat,,, heres the pics u wanted

Oh no sorry, the Amps turn on and off with the car.

HF- thanks for the pics- that's a VERY nice, clean install. I'll show them to my car audio guy soon!

Leathal .. i was like Hmm, was wondering bout that. i added a kill switch cause when i clean my car i would open and close the doors and trunk and the amps would go off and on( and it takes me hours to clean my car ) then my battery would die... So thats why i installed a kill switch. it keeps them off, untill i turn them on,,

thx... Pat. i get alot alot compliments. everyone says inside the car it looks like it came from the factory. I did every thing myself. designed it, drew it up on paper. built the box and installed it all. the only thing i didnt do was connecting the wires to the existing audio harnes had my stereo guy do it cause i didnt wanna fry anything.....
i have alot of time and effort invested into it.. glad u liked it.. im very proud of it. let me know if u need any help.
