Question about Car Audio & Video

I hooked up a stereo system for a friend last night, and he has a 250 watt power acoustic amp, and he bought a 1200 watt amp wiring kit, is the wiring kit to powerful for the amp, because i hooked it all up and it was working but all i could hear from the subs was a slight vibration and a few minutes later the fuse in the amp blew, i ran the wires correctly the power on the driver side and the rca and rem wire on the passenger side could my ground not be properly grounded or what

As I said in the previous post no the wiring kit is just fie. Yo uwill need to change the inline fuse and that is about it. The problem exists in how you have your subwoofers wired and what impedance is being presented to the amp. Please read my previous response to your your post.

    No problem man. From the initial sound of it you have it wired properly. If the fuse in the amp blew it has nothing to do with that wiring. The fuse in the amp is the fuse that resides on the amps power supply. If that fuse blows that means the power amplfier is drawing too much current. This is either due to a shorted output or incorrect wiring of the subwoofer(s)

I have been having a problem with my amp not turning off when the car turns off. The other week I had to recharge my battery because it drained it over night.


You have constant 12v going to your remote. Check your remote wire. You need to hook it to a power source that only powers up when you turn your ignition on. If your stereo doesn’t have a remote wite coming out of the harness you can hook it to power antenna.

I no nothing about hooking these things up my mixer is un powered mixer so i bought a 1200 watt amp to power it mixer yamaha


Humm??? a mixer in a car ?? what a concept !! could bring an entire new dimension to "air guitar on the freeway " but might you mean an equalizer ??? if so its easy to connect a equalizer before the amp as it comes from car stereo , the round "rca" jacks are the best way to do it if you have the means !! then its a simple wire out to each speaker and whoola !! you got sound !!

My kicker 12 inch cvr's arent hitting as hard as they should


amps and wiring kits are very optimistic on the output. If you want proper wire, buy some welding cable "0" or "00" guage. That solves the power delivery. Put a 1 Farrad (or more) capacitor near the amp, that solves the surge power issue. Make sure the box is suitable for the subs. Lastly I'd say do some research and find the right amp that can deliver the clean, huge current required to move some serious air!

I have a 92 marquis, and ive just changed out the factory stereo with a aftermarket. How can i hookup the amp that came with the bose system??


If you bought a wiring adapter kit for the aftermarket stereo, the unit should hook up directly to the stock bose system. Note: If there is sound coming from the speakers after installation, the amp IS hooked up...the speaker wiring is routed to the factory amplifier, not the stereo itself, the stereo wiring is just signal leads to the amplifier. In some instances, you may have to connect the amp remote wire to the remote wire coming from the aftermarket stereo(blue wire). I hope this helps. Any other questions, just reply.

I have a 1200 watt amp and 2 12 in pioneer champions and it keeps killing my battery how do I hook up this capasitor I just bought?


first make sure your power wire is directly hooked to the battery, {make sure ure in line fuse is pulled} power wire that goes to positive of power cap , ground wire is grounded to chasis, now attach aditional power wire to amp and aditonal grond to amp . make sure all conections are solid and tight { also make sure inside of power cap is tight as well after long periods of time the insides loosen } i have 2 -1,000 watt sony xploid amps and 2- 1,200 watt sony expoid subs and they pound hard . i probley should have 2-1.2 farrid caps for what i have but it seems that its holding its own

I hooked up a stereo system for a friend its a 250 watt amp and im using a 1200 watt wiring kit is the kit too high for the amp also i got it hooked up and it was working for a few minutes but all i got...


Let me address the wiring kit first. No the higher wattage kit is not a problem however you will need to change the inline fuse to an amperage that is more suitable for 250 Watts. The amps main fuse will be able to protect the power supply but no need to have a larger fuse than needed.

Now lets talk about the fuse. First off what kind of amp is it? Just for my knowledge. What is the rated impedance that amp can drive bridged mono or stereo (however you have connected it) If the total impedance presented by the woofers is lower than what the amp can drive the amplifiers power supply will demand more current than is designed for. I guess what I need to know is the model of speaker, model of amplifier and size of the inline fuse (right next to battery). Initial diagnosis would say the load on the amp is too large.

Rule of thumb for calculating impedance. The easy way if you have two or more characteristic impedance that are equal then you can add them and divide by the number of impedance to get your total Load however the formula is as follows,

1/((1/Z1)+(1/Z2)+(1/Z3)+(1/Z4)) or (Z1^-1 +Z2^-1+Z3^-1+Z4^-1)^-1
(They are the same thing, just written differently)

In electrical terms Z is your impedance, the negative exponent just means reciprocal.

So in your case if you have 2 dual voice coil subwoofers with a 4 ohm per coil impedance. If you parallel the two coils you would have a 2 ohm impedance. Then if you parallel the two woofers you would have a 1 ohm impedance. This is to low of a load for your amp to drive.

Let me know

What amp will push 2 kicker 15inch cvr's


Hello herb31,

Kicker lists the RMS power handling range of the CVR's from 100-500 watts, with a peak power capability of 1000 watts. There are lots of monoblock amps within that range. It just depends on how loud you want them and how much you want to spend.

In the low range, an amp like the Alpine MRP-M500 will deliver 250 watts to each sub at 2 ohms. And it only costs $179. Currently, the MRP-M500 is out of stock at Crutchfield. I just bought the last one. So my 2nd recommendation would be the Sony XM-1S, which has the same power rating and according to Crutchfield is no slouch either. It's also $179. I really like the Sony, too. It has a small footprint that makes it easy to find a convenient mounting location. Both the Sony and the Alpine are CEA-2006 compliant, so you can be sure that the manufacturer provided specifications are not overrated. Assuming that your vehicle electrical system can deliver the current, both the Sony and the Alpine will deliver an honest 250 watts RMS to each of your Kickers. And 250 watts will make them kick pretty darned good.

In the medium power range, consider either the JL Audio G Series G1700 which delivers 700 watts into 2 ohms. It costs $419 at Crutchfield. Or perhaps the Kicker 08ZX750 with 750 watts at a cost of $399.

To push the CVR's really hard, close to their 500 watt RMS maximum power range, look for an amp that delivers 1000 watts. In this range, you will definitely some heavy-duty wiring, electrical system upgrades, perhaps a 2 farad capacitor, and be ready to spend at least $600 on the amp. Your best combination of power and price would be another Alpine, the PDX-1.1000M, at $799. If you buy one from Crutchfield, they will throw in a 4-gauge amp wiring kit. And if you use a "friend referral code", such as mine, which is p7sdj-hrx8q-9800g, and your order is at least $200, you'll get another $20 discount. And I get a $20 credit toward a future order.

Hope this helps. If it does, please rate as "FixYa".

Need to hook up bass system to 1999 ford explorer can anyone assist me


Probably need an installer - depends on yr/make/model of car - stereo and wiring diagram for sub system. There are lots of questions need answering and if not installed properly, you can certainly damage the stereo, sub system. Subs use a lot of power and improper wiring could cause problems, even fires !
