Open Question

Hi there, I have a MAYSTAR QXT250 AMP, a radio/cd player and a 10inch sub Woofer. My problem is that I haven;t got a clue how to wire it up. I tried Once before only for smoke to pour out of the amp. I quickly disconnected The battery and have noyt tried since. The system came with the Nissan 200sx I bought and thetefore I have no manuals. If anyone can help I would be Very grateful as I much prefer listening to sounds instead of the engine. Regards in advance. Steve. Steve.milligan@o2email.co.uk

Hi yeahonda,

 

Your Kicker L7 Ohms may be too low for the MA Audio Mono block amp. The MA Audio Amp is probably 2 Ohm Stable. The kicker will either be 2 ohm or 4 ohm Dual voice coil.   To eliminate the low ohms as a possible threat to causing the map to go into Protect, Wire the kicker Voice Coils in Series.  This adds the ohms, so that you either have 4 or 8 ohms. 

I am using the following codes to show wiring. VC1+ stands for the Kicker  Subs Voice Coil #1 Postive post. AO+ is the MA audio Amp output positive.

 

AO+ to VC1+

VC1- to VC2+

VC2- to AO-

 

This shopuld give you 4 or 8 ohm depending on the 15" L7 setup.  Crutchfield does not carry the Kicker  L7 in 15" They do  have the L5 in 15".

 

If you know how to read a Volt Ohm Meter, set it to OHMs 20 and measure across VC1+ to VC1- and you should see between 1.5 and 5 ohms..  Do the Same with VC2+ to VC2-.  you should see the same voltage. Also read from the Voice coil metal housing to VC1+ , VC1-, VC2+, and VC2-. and you should not read any ohmage to the case. The meter should say OL, or -1.

Good luck.

SOURCE: one of 2 subs stopped working.

you have too much power. Although the power is 250 watts a piece. you should never apply the full strength of what the speaker is made for; and if you do the reliability of your speaker will deminish. Hense only one year in your case.

SOURCE: Do you know if my woofer is blown?

well if you hear a rattle sound its probably already blown...and the amp could be drawing too much power if the radio shuts off...make sure all your wiring is correct. also if your car is off and you turn it up it will most likely shut off cause the battery cant handle it. but as for the sub i think its blown. good luck

What is the color code for sub woofer control on alpine cda-9856 wiring?


Hi there,
Well I found out on Pages 34 & 35 of the following Alpine manual:

http://vault.alpine-usa.com/products/documents/OM%20CDA-9856.PDF

---------------------
The Remote / Amplifier Turn On is a Blue/White wire.

When the radio is on the sound comes out of all the speakers. when the cd player is on the sound only comes out of the sub woofer


are you running separate amps for the woofer and speakers??? sounds like you have the woofer amp being turned on be the amp remote wire (blue/white) and the speaker amp turned on with the power antenna remote wire (blue). if this is the case you need to use the blue/white to turn both amps on.

PIONEER 300 WATT CAR STEREO AMP WIREING HOW TOO


depending on how many channels the amp is, you may not be able to hook everything up to it.

usually you have a separate amp for subs. 4 channel amp for the speakers in the car, and a mono amp for the subs.

To hook them all up to the same amp you would need an amp with 5 channels. It wouldn't work out right.

If you have a mono amp its only for subs.

If you have a 2 channel you can either hook it up to the rear speakers or bridge them to mono to run the subs.


you need a channel per speaker basically.

Maystar MX2200 200 watt Mofset Amp. Single Sub Car wiring


The inline fuse goes on the power wire (as close to battery as possible), and is there for a sfety feature to keep from sending to much power to the amp. All it does, is simply blow if the power gets over the specified amperage. For your amp, I would use a 40-60 amp fuse.

The remote power line, is simply an 18 gauge wire, running from the headunit to the amp. All it does is tell the amp when to power up. Since the amp is straight to the battery, it is possible to be on at all times, so you run it to the amp so it knows when to be on. If your headunit doesnt have a remote turn on wire, then tou need to run it from the ingnition to the amp.

For a signal cable, I recommend getting an rca cable to run to the amp from the headunit. Make sure when you run it that you run it away from the power wire to prevent from having engine noise.

You also need a ground wire, wich should be to a stud on the frame of your car, as close to the amp as possible.

When hooking up your amp to the sub, you need to run the negative to the negative (black to black) and the positive to the positive (red to red).

No sound


hi there
on your CD deck or what ever unit you plugged the RCA wires to needs to be set on subs the radio needs to be set to put sound to your amp.....on your CD player if you press the F/function button a few times it will scroll to SW which is for the subs set this to the on position or if your CD player has a button with SW press it and turn on this feature......if this has been done......check the fuse or fuses on the amp.......if you have done all of the above check the back of the CD unit to make sure you are plugged into sub-woofer RCA or R (rear) RCA ..........sometimes people accidentally put the RCA wires into the aux input RCA,,,,,, double check this.........
hope this helps

Radio wiring problem 2001 Audi A3


Hi, had total issues with this too! Your back speakers arent going because they are amped by the factory amp in the boot. You have to provide power to the amp so that it will turn the rear speakers on. This was a white and black striped wire in my car (Audi A3 1997) The rear speakers are blue /green and brown/red (left rear) , and the LH rear is brown/red and (forgotten colour) but the wire on the bottom left under those two brown/red wires on the 20pin harness. If you wire it all up like this then your rears should be going :)

alot of times its not just the amp that gives you better sounding bass.. A lot has a to do with a few other factors as well.. first off your subwoofer.. the bigger the subwoofer the deeper the bass. Some woofers exturde, or flex differently depending on the quality and structure of the woofer.. 2nd is gonna be the sub box. different size boxes will give your sub diff. depths of bass. ... general idea is the bigger the box deeper the bass. But if your woofer is not supplied enough power a big box is useless.   With that size amp your best bet is too run a single woofer. Probably a 10inch woofer would sound the best.. but it in.75cub inch. sealed box.. should sound great.

No Subwoofer output


the connections to the amp seem to be all wrong .check the wiring again.Does your deck have a seperate sub woofer output ?If it does , just connect one sub, i repeat, just one sub,and see the output.
OR
check the GAIN control on the amp.it should be 2/3rds of the max volume of the cd player.check it is not zero!
AND
Set the amp to the L.P.F. position.
bye .happy listening.
