Re: american pro vs1403 lost one channel out of four
I also want to add, I just got a crossfire ct-2200 oldschool amp I bought from E-Bay and the description described it to be as one channel not working but other side plays fine. Well, when I got it took it apart did basic test everthing turned out fine. So I hooked it up turned the power on and one channel was'nt playing. I thought maybe something in the input circuit in the amp, the preamp section maybe an opamp. Anyway it turned out to be the sub frquency switch and the stereo or bridge selector switches had sirty contacts. So I sprayed some contact cleaner in them and then a little WD40 to keep them lubricated for sliding. So maybe that might help you out also. Once again, Good luck and let us know what you find out.

You can but you will have to wire your subs in parallel....to a 4 ohm load then bridge it to your amplifier.....look up parallel wiring on google....Im pretty sure you will have to run jumper wires from your positive and negative of one sub to the positive and negative of the other sub.....then run the two wires to your amp bridged.....to make a 4ohm load.....let me know if that helps you and gd luck!!!!
Your amp is a four channel so you have 4 sets of speaker outputs. to bridge this amp to 2 channels is pretty simple, all your have to do is when connecting your speakers instead of using both +, and - from the same channel, use the + from the one channel, and the - from the adjacent channel. Do this for both speakers, if you'll notice you now have 2 empty - terminals and 2 empty + terminals, if so you did it right... Hope this helps, enjoy your amp.
Your amp is blowing fuses to protect your circuit. The type of 12V battery does not matter. For whatever reason you are over driving the amp. 2 Ohms sounds like a very low impedance for a car amplifier output. I am assuming you have the two 12" speakers wired in parallel. Most are rated at 4 Ohms which means you are pulling twice the current with the 2 Ohm load. Also, the bigger the speaker, the bigger the magnet, the bigger the coil, the larger the inductance, the heavier the load. Make sure these speakers are matched with your amp. A small amp driving large speakers will shut down at high volumes. Try putting them in different channels. Good Luck.
You should go to www.the12volt.com they are very helpful and pretty much have a schematic for every single car audio situation and they give you all your options. If they have nothing go to crutchfield.com and go to the learning section then subwoofer and amp wiring. It all depends on the subs that u wanna hook up to it as well as the ohm impedence and the amount of voice coils and so forth they have all of that.
well yeah thats what im doin riht now in my ford taurs what u do is u can hook up your 5x7s and ur 6x9s on ur amp sill have room for a sub the way too do that is get the front speakers off the amp just run the back andsince its a four channlel amp 1 and 2 channel are used for the back and 3 and four are used for thesub of couse u brige the sub to the amp 3 and four are used for the sub hope that helps friend let me no what happens
I'd make sure that the receiver surround mode is set for one of the digital settings, such as Dolby Digital or DTS, and make sure that you have the center channel level adjusted to a level similar to the other two front channel speakers. I've seen/heard this happening when using dolby digital material & having surround set on something like 'hall' or 'stadium' or dolby surround, where only 4 channels are used & the amp has to 'mix' sounds to the left & right front speakers. It'll often sound like the actors on screen are talking out of the bottom of a barrel, with a hollow & tinny character to the voices.
