F**.. i had a huge post liek the last one that was perfect, and it got deleted.. =/ .. haha..

again
For TI
haha..okay, so I didn’t do the math for the DB .. also, after re-reading this (i was tired when i wrote this, and had to write a huge English paper that was due) i meant 83 DB really, which is a popular DB for cheaper or higher wattage subs. (88 DB is really a half decent DB rating) anything OVER 90 DB is a good loud speaker. so 88 would be alright, and 93 or more is prime for those that want a high quality system with little money.

anyway.. ohms is a tricky thing to figure out when it coems to a system, and really depends on the speakers individually for sound output. (yeah over all I was thinking about something else, but read what i have for him)


anyway, Gambit:

yeah, sorry I went a little off topic with amps in my last post. I was just trying to explain that you probably wont get what u want unless u have one. Also.. can you tell me the brand, model, DB rating, and watts of the 5 ¼ inch speakers you are trying to install? Just installing alpine r speakers probably wont fix the problem a whole lot if the speakers your are trying to stick in now have an OK DB rating. The alpine will probably sounds better and have a higher wattage and a slightly higher db, but probably not going to fix the problem.


if you do have 2 door speakers, the kick speakers are fighting with the door speakers for power. Since the kick speaker WAS 8 ohms, changing it to a 4 ohm speaker would have upset the balance, and made the KICK speaker louder in the new system, then the last one... its probably making the door speakers more quite, and the kickers louder (or about the same as before, since a small reduction of power in a small tweeter means u are losing a lot of sound, which u aren’t gaining back in the 5 ¼ kicker speaker. )


also, depending on your old system, and how you hooked up your new system, you probably HAVE an amp already installed in your car.. my car came with a small amp in the rear left trunk panel. What happens is if you hook up your car radio like the old one was hooked up, your radio’s power gets dumped into the BMW amp, then sent to your speakers.

what I am getting to is you maybe be able to cheat, and do one of 2 things with that BMW amp.

You can add your crossover there, which will add more bass to your kickers, and change the sound at your door panels. (it wont do much anyway, but you are limited with out an amp)

or you can use the BMW amp to power the kicker speakers ONLY and then use your radio’s front speaker output and rear speaker output to power everything else. (but that is alittle harder to do, and you need to remove your BMW AMP, find the wires, cutthe old ones, splice into them, and run them to the output side of the amp)
Then the amp will ONLY power the Kicker speakers.

I don’t know anything about the BMW amp, and if you would like to do that, I would look into it more for u, and help you out.. (im not sureif u can because i havnt looked at the BMW amp.. i have a real amp, and cut that amp out of my car.. )

I you DON’T have door speakers, then I have no idea other then u got crappy speakers with low DB .. haha.. or they ARNT angled in the right direction, and the sound is just pouring into the carpet of your BMW, and u hear muffled sounds.


if u do decide to go with an aftermarket amp.. let me know.. really, if you are just looking to add a little bass without an extra speaker, and your kicker speakers are solid, without a tweeter strapped on them, you can just pick up a cheap $30 amp, and it will work perfectly. All you have to do is find the BMW amp, splice into the wires before the BMW amp, and use the HIGH power input on your aftermarket amp. Then for the output of the aftermarket amp, splice into the wires going to your kickers(coming off the BMW amp) . They are the biggest speakers in your car, and the amp will allow you to make them much louder and much more bassy (if you want) you will have more control of them.. total cost shouldn’t be to much. You only need like a 100 watt amp (50 - 75 watts RMS meaning 100 – 150 watts rated) , 2 channels.. which are cheap online, used or new. Then u only need like 14 AWG wire, and you can run it to your cig lighter if you want. (the amp doesn’t draw to much power when they are that small.) then you ground the amp where the BMW amp is grounded. .. not to hard, and shouldn’t cost more then $40 – $50 .. .. I would do it for free if u lived close to me, since it wouldn’t take me more then an hour. you can probally even pick up a used amp that small for like $20 locally or online, and the wire cost about $3 depending on where u get it.

---sorry about my HUGE post.. haha--
