    the receiver is a yamaha and is very nice. Well, it was in tis hay day. The model is RX-V659. What exactly is a subwoofer receiver? how would i use it or get one? The subwoofer is not plugged into anything than the wires going from the woofer to the receiver, and there is no power cord comming from the woofer

The sub woofer most likely needs to be powered, is it also plugged into the wall? Otherwise it's not receiving an amplified signal strong enough to move it's diaphram.

    Then you need an amplified output on your receiver. If it's a inexpensive receiver or part of a home theatre in a box kit then it probably doesn't have one. MOST subwoofers are powered and the signal comming from the receiver has very low power.



    Another option would be the connect some kind of subwoofer amplifer between the receiver and sub. You would need to know what the wattage is of the sub and find a suitable amp. I looked around the web and that doesn't seem to be a very popular item. :-(



    Sorry! I take it the sub didn't come with the receiver then.

    A subwoofer amplifier is a device that would amplify the subwoofer signal from your receiver to a stronger signal that would drive your subwoofer. Kinda like the ones used in car audio. I have never seen one of these as the amplifier is usually always built right into the sub. Speak to someone at your local stereo shop, they may be able to point you toward an amplifier. Like I said I didn't see anything on Google so they might not even exist.

How can I connect Bose 901 (speakers) to Sony STR-dh 520?


If you're using them in front then connect them via 2 wire (16 gauge or 14 guage) speaker wires to the back of the Sony unit. They're labeled left / right (as you would see speakers from the normal vantage point.) and front or rear. Make sure you get the pos/neg connections right. These are collored red (pos)/ Black (neg) on the sony and I believe they're red/black on the back of the bose speakers as well.

Wiring diagrams for clarion dxz535 car stereo


Here's how it goes:
Speaker wires:
grey=right front pos.
grey/black=right front neg.
white=left front pos.
white/black=left front neg.
violet=right rear pos.
violet/black=right rear neg.
green=left rear pos.
green/black=left rear neg.
red=12 volt switched power source
yellow=12 volt constant power source (direct to battery)
black=chassis ground
orange/white=illumination (switched source,not to head light switch)
blue/white=amp turn on lead (to remote turn on lead of amp)
blue=auto antenna (switched power source)
brown=phone mute lead (to cell phone mute lead)
RCA connector leads:
grey lead:
red=right front
white=left front
black lead:
red=right rear/right rear subwoofer
white=left rear/left rear subwoofer
(connect to external amp)
red lead:
red=right aux input
white=left aux input
(connect to external unit)
green lead:
red=right dual zone output
white=left dual zone output
(connect to wireless head phones)
That should be all there is. on the yellow that goes direct to the battery you need to use an inline fuse holder with 30 amp fuse.

Have a 2000 gmc sierra ext cab pickup and two type R swr-1042d subs and would like to know the best enclosure for the subs to get maximum performance and the best ways to hook up a one channel mono alpine...


it depends on the amp what can it handle. will it do 2 4 or 8 ohm is it 1 ohm stable are the subs dual 2 ohms or dual 4 ohms. 1042s are dual 4 ohm subs so if you wire them both in paralel it will drop both subs into a 2 ohm load for each sub that is pos of one coil to pos of sec coil then pos to pos on amp and same with neg to neg to neg on amp. now if your amp is 1 ohm stable i would do both subs the same way you will get the most power out of the amp. but itll run a littl hot if you dont have adaquate power running to the amp. now i wanna think your alpine amp maybe only 4 ohm stable. i would run both subs like i had said pos to pos then neg to neg now both subs will be a 2 ohm load so what you do to bring it back up to 4 is you run the 2 bridged subs into a series which is pos from one sub to neg of the other sub the remaining pos and neg will run to the amps pos and neg. which will make it into a 4 ohm load. now the last scenereo is your amp is 4 ohm or 2 ohm stable. this is how to wire it to 2 ohms and not 1. take one sub go pos to neg then pos to pos on amp and neg to neg on amp this will make an 8 ohm load with one sub take other sub and do the same neg to pos on sub then pos to pos on amp and neg to neg on amp this will tell amp to run a 2 ohm load. 2 ohms is a good run for these subs if the amp can handle a 2 ohm load. now if you would have given the amp model number i could have looked it up to just give you what you needed but with this short info i gave all possibilities.

8 wires on my subwoofer??


"One has positive and negative input, another positive and negative output (red and black on each)"

Just from your description, it sounds like pos/neg input are the 12 volt pos neg supply for the amp inside the subwoofer. Red is pos, black is neg.

"positive and negative output (red and black on each)"

This sounds like it's used if you want to proved 12 volt pos/neg to another component.

"and a third wire with left input right input positive and negative (blue, red, yellow and black)"

This is for the cables coming from the "subwoofer out" on the amp. This is 4 wires altogether -- correct?

How to wire my kicker solar baric


All depends on your amp. Is it 1 ohm stable or not?
Parralell:
positive (pos) on voice coil 1 (vc1) to Pos on vc2 and negative (neg) on vc1 to neg on vc2. Then speaker wire from amp to one vc only = 1ohm load.
Series:
Pos from amp to Pos on vc1. Neg of vc1 to Pos of vc2. Neg of vc2 to amp = 4 ohm load.

Neg and a pos on each side of car speakers


Depends on your amp. If they are dual 4 and your amp is 1 ohm stable and you have 2 subs, wire red to red and then red to plus on the amp. If your amp isnt 1 ohm stable wire ch1 red to + on amp, ch1 black to ch2 red, then ch 2 black to - on amp. If this sounds like french to you, go to a stereo shop in your area and pay them to hook up your stuff. It will be a lot cheaper than buying a new amp and subs.
