Audio upgrade, any suggestions?

Hi guys, I got a "04" 325xi and I just want to add a 10 inch sub and maybe upgrade my factory speakers. I already installed the Ipod player to my stock radio.
My question(s) are: Can I add a sub/amp to the business radio without a degree in engineering?
And also (I know I can, BUT) would it be smart to replace my door and back shelf speakers with aftermarket (non BMW) speakers?

I like my factory radio with the steering wheel controls and the amp has enough power for me but if I have to replace the whole head unit to make the upgrades possible, (or a whoooooole lot easier) I'm an audiophile so I wouldn't mind.

yea just get a converter that converts speaker level signal to audio level signal and plug into the sub amp.

Ok. But are there dedicated sub wires behind the head/trunk or would I have to splice into the rears?

check out www.bavsound.com if you haven't already. When it comes to good audio you get what you pay for so walmart speakers just don't cut it.

I drive a BMW AND I'm an audiophile. Why would I go to walmart to fulfill my audio wants? I know about Bavsound, I'm just wondering if I could go another route without much headache? I'm thinking along the lines of Sony, JBL, Infinity.....Thanks

^ The BSW kit is the most pain free way to get what you want. It's not cheap but it's plug and play. If you want to go and wire in other components, you are going to have one hell of a time doing it unless you're planning on swapping out the stock amp and everything else too.

Good luck.

All the tips posted are heading you in the right direction. One point to consider is how well the XI snuffs trunk audio. Basically, the metal backing behind the rear seat is solid and covered with insulation. Some hog out holes or punch the ski pass-through plate out. They stick a sub box in the trunk or go $$ nutty with a deck mounted sub. Owners that don't "vent" for bass waves claim a sub sounds "stuffy" in our isolation chambers (trunk).

Tapping the "hot" (speaker level) lines for your sub solution is the deal. There are NO pre-amp (line-level) sends from the head available at the trunk mounted, 10 channel, factory amp. These are non-conventional systems. Should you want to start over with a new head, common amps and speakers, prepare to pull shielded wiring front to rear.

My "fix" is probably not very common. I routed the rear deck, mid-bass factory amp speaker outputs to an aftermarket amp's inputs. With a little "massaging", two new high-excursion, 6", 4-ohm, sub/bass speakers were installed where the mid-bass buggers were. The 400w amp has an active cross-over set to 80hz and below for the now low-bass speaks. I roll the factory head F/R balance slightly rear. For volume levels I enjoy, she now adds a sweet amount of the lacking bass in. Bone-jarring sub-freq thump? Um, not so much but authoritative, punchy bass is definitely there in correct, cabin filling phase. No muff stuff. I retained all other factory speakers and have no urgent need to chuck them. Total upgrade cost was around $400.

Hey White_Knuckles, your the best man! Before I started this whole idea of a sub in the trunk I was thinking just what you said, replace the decks with with low freq direct replacement 8's. Great minds really do think alike. My ski pass thru aready has the hole in it that passes thru to the trunk and I already ordered a low profile 12 inch box for the sub I'm going to put directly centered through the hole so I'm thinking I'll go the inline RCA adapter route for less fuss. I like to feel my bass just a little,and I know a 12 can reach down a little further to grab those lows a little better than those 8's on the deck. I don't wanna wake the neighborhood but I do listen to quite a bit of rap music and the 808 sound must come thru for me to really get the experience I'm jones'n for.

I already have a few high powered 12's and amps laying around the house from building systems in my other cars anyway so that'll cut down on the cost significantly. Like I said, the door speakers and deck speakers play well enough for my taste (right now) I'm just lacking the low end I like so much.

I'll take a couple of pics and let you know how it turned out. Plus Im gearing up for a front left and right axle swap, trans and diff fluid change. My boots are leaking so I'm preparing. I got the axles right here beside me now. Im about to order up all the fluids i need. I might as well change the axle seal while Im under there too right?

What are the chances that you have the ski-pass cassette and bag? Or did you actually have to knock out the metal yourself?

Speaker level to line level converters are fine just buy a good one. Something in the $20+ range. Some of those products are junk introducing noise. The powered or active units are best but spendy.

I went the complex route and installed two amplifiers with signal cables routed thru the stock wiring loom gromments behind the backrests in my XI.
It was alotta work and not easy but i'm happy with the end result.
