I have an old car subwoofer that I want to hook up to my home reciever, but I have no clue how. Is there anything special I have to do to get it to work? Is it possible to get the 12-volt DC amplifier to run off of 110-volt AC power?
yeh you need a ac to dc inverter, i think i saw some of these at radio shack, that would provide you with enough power im sure, http://www.radioshack.com/product.a...y_name=CTLG_009_001_005_000&product_id=22-510 theres some others, this one is 100 bucks. -sean
seanZ0r is correct.i would recommend that you run your sub off of the amplifier so you have a low-pass crossover for the sub.i did this once a few years ago and it worked ok.i had a band-pass box as a coffee table,many drinks spilled. careful hooking a 4 ohm car audio sub into a home receiver meant for 8 ohms though,if you use the amp it won't be a problem.
can somebody tell me how to hook up home audio speakers into the trunk of my car to replace my 6-9's. Thanx themancf@yahoo.com
no posting e-mails, against forum rules.. http://forums.afterdawn.com/thread_view.cfm/74142 and by the way, why would you want to replace 6x9's with home audio speakers, when you can just by you a car audio bow with speakers for cheap and have less hassle anyway?
my friend put a 300 watt sub into my car and I'm having 2 problems... the first problem is very weird... we hooked the thin power wire to the fuse box so when i turn the car into ignition II or when the car is on, the sub is on. Whenever I turn off the cd player but still have the car on, or have it in ignition II, the sub will just get very loud and and have a constant sub noise... like it's stuck on one beat. The second problem is when i play my sub, i can hear the voices coming out of it... I thought it was only suppose to play bass and nothing else? That’s how it was advertised in best buy. How to I make it so it only plays the bass and nothing else. I'm pretty sure it does this because we tapped into the 2 back speakers instead of running a wire all the way to the head unit but I’m not sure. Thanks
ste0matic....fist of all when u hear noise like that .. it means u didnot hook the wire right. first of all, i guess u should have a cd player and the power amp and the sub right. ur cd player should have a red wire (this is the ignition wire, u should hook this to the ignition wire from ur car) and a yellow wire from the cd player (u should hook it to the batery +) the blue wire from the cd player is the remote key (this hook direct to the power amp remote +) to turn on and off the amp or u can use the power ant wire from the cd player it does the same task. the black from the cd p is the ground wire( remember ground it good) so u wont hear a hissing sound..and the rest of the wires are just speakers wire. From the power amp u should have ground input ( ground this to the car chasic with the 8 g wire, batery + (run this wire to the car batery + with 8 g wire, and remote( hook this to the remote wire from the cd player or power ant from the cd player) and the rest just speakers or sub. second if u just want bass only. u should get a crossover this device will control bass, mid range and tweeter.or set ur power amp to low frequency or at 80 hz.. hope this help.
thanks, it sort of helped... the problem with the weird sound was that the 8g power wire was too close to another wire... all i did was move them away from eachother and it worked. As far as buying the crossover... how much does that cost... and is it worth it?
It is a common thing in both home and/or car audio - a low-pass filter. It filters out anything above 80Hz (or whatever its specification). Every 3-way speaker has one on the woofer. You can select your desired frequency and then purchase and apply the proper filter capacitor; it is inexpensive. This is a non-adjustable, static, low-pass filter. It is passive. Not to be confused with an active crossover that is adjustable for all sorts of high-pass and low-pass functions - they are less inexpensive :^) L8R
equalizers do the same function, again, not to be confused with active. passive means, non powered, relies on an external power source, ie; amplifier. a good e.q. will do the same as a crossover, cost is similiar, there are also bass blockers available in varying frequencies, but you have to install them inline on the power wire to the speaker, takes time, but is a cheap alternative. i have an old school kenwood eq, like 10 years old now, but is the sh*t for my system... but i installed all my car audio myself, as well as my home theater, really simple, as long as you know electricity and frequency.
