A small spark when reconnecting the battery cable is normal
no spark at all would be a concern sice that uaually only happens with a dead battery.

How to install a wired fuse between battery and amp


Fuse rating is based on the guage of wire it's to protect.
Install the fuse holder close ...within a foot...to battery positive connection.
You may require a different battery cable clamp to accept your new amp wire (and the existing wiring).
Occasionally, it's possible to use an unused location in a vehicles power distribution panel (the fuse box close to the battery - under the hood). Sometimes appropriate for small to mid-draw amps, in certain vehicles, where some high draw options were not factory installed.

Tip

Save your charging,and electrical system when installing a audio amp.


Every one wants the BIG amp,the more powerful,the better right?When installing an audio amp,it is good to install a addition battery,in the trunk, it is the idea place,just ground the battery to the frame or body,to a good know ground,It needs to be a large cable,1/o wire,yeah,that is big,but will keep you from having problems,then run a 1/o positive cable from the aux battery you have just put in the trunk,to the main battery in the vehicle,use a 3/4 heater hose to insulate the positive cable you have just installed.This heater hose will prevent a portion of the cable to be rubbed threw on the insulation of the cable and shorting out.Then install the amp.Now ,for better electrical control over the charging system of the vehicle,you can install a isolator ,to separate the circuit,and still charge the battery up with the vehicles alternator.Install the isolator at the vehicles battery and the positive cable you just ran.The alternator will charge the aux battery,and the vehicles battery,and not affect the running of the vehicles engine,or charging system.Be sure to connect the amp to the aux battery only,and the aux battery needs to be a good strong battery such as a 65 style battery such as for a full size ford crown victoria.These batteries are full of power.There you are,you are ready to thump,and do it safely .You need to install a fuse holder between the positive cable from the aux battery and the isolator,use a max link fuse holder and fuse,and a strong 60 or 80 amp fuse,this will blow into before starting a fire,.

I plug in rockwood detanator VII and it goes to protections mode


Generally if an amp goes straight into protection, the amp is not grounded well enough. Either you should find a new location to ground the amp to or unhook the power wire from the battery, remove the ground wire from the chassis of your vehicle. Strip the paint from the chassis, since it doesn't conduct electricity, and remove any corrosion or copper shielding from the ground connector. reground to a solid metal location Can be grounded to the brace behind the back seat or to the seat belt bolt for best results.
An amp draws a lot of power, there it needs to be grounded well.
Hook back up your power wire to the battery and see if your issue is resolved.

Install dual xd1222 into a 1993 dodge intrepid


The best way is to get a stereo installation kit designed for your car. It will have the surround for the new stereo to fit where the stock stereo fit. Also, it comes with a wiring harness that you connect the new stereo to then it plugs in to the stock radio plug. Most local automotive stereo stores should carry them.

I have a brand new soundstream xxx 6500d amplifier and when i installed it for the first time protect mode light come on even without rca jacks and speaker wires hooked up. any1 can help?


You need to plug in the RCA and speakers you could blow the amp. The amp is sensing no Input and No output. I would unplug the amp wait around 30 seconds then install the rca and speakers THEN install amp to battery + cable. You should be ok.

How do I install my Pioneer MOSFET 50wx4 Super TunerIII in my '93 Jeep Cherokee?


When you go out and buy a new stereo make sure to buy a wire harness kit and a mounting kit. The back of these packages will tell you if it will work for your vehicle. As long as your son properly removed the old stereo, all you should have to do is plug one end of the wire harness into your stereo, the other end into your car, and you're done, no wiring needed. If he cut the wires you may be better off going to an auto shop of some sort to have it installed.

How to connect 2 Amps for my car audio system


Hi,

Based on your post, you actually have 2 concerns:
1. Power - Normally this is the +12V straight from the battery + terminal. If the existing power wire from the battery to your old amplifier is capable of carrying the combined current (in Amps) of the current + the new, then it is simply running an extension of the B+ line (usually big red wire) from the old amp to the new amp. The negative/ground is simply connecting to the chassis/exposed metal part of the vehicle.
On the other hand, if the old amplifier uses a rather not so big wire to supply it from the battery, you are better running another bigger wire from the same battery terminal to the new amplifier.
You have to check how much current the amp will draw from the battery and select a wire that is capable of carrying that much current without heating up. Offhand a #8 AWG would suffice for most single amp.

2. "Where does the Line cables go?" If you are referring to the Line INputs of your new amp, they maybe connected to the RCA OUTput (line level) of the old amp (it it's got one). Alternately, if the old amp has only INputs and your new amp has both INputs and OUTputs, remove the RCA connection to the old amp and plug them in to the new amp. Thereafter connect another pair of RCA male cables from the output of the new amp to the inputs of the old amp.
If neither of the new or the old amps has an OUTput RCA female, you may need to use a splitter of some sort. Below is an image of a two female RCA to a single RCA male.
b6f5283.jpg
You can hook it up in many ways. The simplest would be to remove your existing RCA connection to the old amp, plug in the double female/1male to the INput of your old amp. Connect the cable from the head unit to one of the female RCA. Connect another pair to the other female and the other end to the input of the new amp.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

Amp fix


if you are still trying to power it, stop now... disconnect the amp and remove it from the car, if it is under warranty, rma it... if not, take the case off the amp to expose the circuit board, and remove any fuses. go down to autozone and pick up a can of CRC QD Electronic Cleaner... it's 11oz and goes for 5 bux or so...

remove the circuit board from the housing, spray a liberal coating to the underside of the board, then flip it over so you can see all of the components, prop it up on something so that it can drain easily and empty the rest of the can onto the top side of the board, get into every component you can using the supplied tube... let it dry for a good 45 minutes, i usually put a quadded up piece of paper or a hand towel under it so that i can gauge dryness... when the runoff soaking the towel is dry, there is a good chance the board is dry...

after you are certain it is dry (may want to wait 24 hours just to be safe) re-assemble, replace any fuses, power it up and see if it works... if it does not work at this point, your best bet will be replacing it or taking it to a local electronics shop to get a repair quote..

water seldom actually damages components unless you power them on while wet, even then it is usually possible to heavily clean the components and have the device work again. this is the method i use to determine if amps and stereos are worth saving after water gets into our open jeeps or trucks.. if water is going to be a normal foe in your vehicle, i would recommend modifying a waterproof battery box or toolbox to hold your amp. In my vehicle i currently have 2 amps installed in a waterproof battery box and am using two 60mm computer fans in the top for cooling.

hope this helps
