I have recently upgraded my home stereo amp. The previous home stereo and amp came with 2 speakers, each having 4 wires for 4 speaker output connections on the amp for each speaker. My new amp has 2 speaker output connections for each speaker, + and - . Can I hook up the 4 wire speakers to the 2 wire speaker connections on my new amp and if so, how?

parallel is all positives (Red+) to all + and then keep all the negative's (Black -) together hooking them to the amp. if you dont have the big 3 upgrade (extra battery thick wire 0-4 AWG wire and an extra battery) keep it to 2 or 4 ohms and google impedance calculator and go from there. also just because your amp is 1 ohm stable doesn't mean it won't break it at 1 ohm and cranked up all the way
One thing to remember about most radios, the RCA pre amp circuit will still work even if the mosfet power amp inside the radio does not. The best way to know if the amp inside the radio works is to use one matching color pair coming off the radio to wire up a random speaker right to the radio. You can use just about any old random 4 ohm speaker that is laying around to check it. The best solution if the amp inside the radio is blown is to replace the radio or amp the pre amp outputs with a small 4 channel amp. Oh, by the way. What vehicle are you connecting this into? And does the vehicle say Bose, Infinity, or ect sound or Premium sound? These usually denote a factory amplifyer already onboard and requires special connections to get the signal to these amps to then be delivered to the speakers.
(http://inform3.kenwoodusa.com/manuals%5CKTSMP400MR.pdf ) Here's a link to manual and wiring on page 30 on the PDF file. Yellow is constant power from battery, for memory etc. Red should be to switched source.If need be, you can connect both to battery, but remember, you'll have constant power draw on battery when stereo left on but switch turned off, and will draw battery down, if you forget to shut it off, and leave the boat. Speaker negatives to black should work but I would advise hooking my 2 right and 2 left + speaker wires from stereo together, then to one of the speaker positives,right or left for better sound. Fronts will usually supply higher ( high and mid range), and rears will supply lower sounds (woofer) Joining them together will give better sound usually, when only using 2 speakers, on a 4 speaker stereo. You may want to test with them joined and not, to see what sound you like better.
the 2 left and right dont matter, it only matters when ur hooking up a 4 channel amp. all u do is connect one of the channels to it but it would be best o buy a stereo ull have alot of engine nose and vibration on ur speakers and a thump every time u turn on ur car but itll sound ok for now ti
If you have an aftermarket stereo, the hook up is fairly simple. On your amp there should be a minimum of 5 terminals and an audio input. one is for remote which is connected to the blue wire on your stereo. Second is your ground which is your negative connection. it should be connected to the body of the car close to the frame. Third is your hotwire which is the positive lead, it should go straight to your battery. The fourth and fifth are speaker wires, you may have 2 or more of these that have + and - signs above or below them. When wiring the speakers make sure to match the positive and negative connections on the speakers. If your rewiring all of the door speakers to your new amp then the colors that you see once you have them out are the colors you route to the appropriate locations on your amp. If this is for a sub then you just the connect th positive terminal on the sub which is red to the + on the amp and the black terminal on the sub the the - location on the amp.
Lastley there should be an audio input that runs from your stereo to your amplifier. This wire should be ran as far away from the positive wire as possible to avoid engine noise coming through your speakers.
As much as it might sound retarded i want to suggest to you that intead of all that hongkong stuff- just go to walmart and get the sony package that comes with the deck/cdplayer and the 4 speakers it comes with a pair of door speakers and a set of 6x9s and all the wiring that you need for a basic install-plus the deck has the rca pre-outs to install an amp. Get an amp and subs from a pawn shop at least you can be sure that it works before you buy it that way- I'm not knocking your idea, but it could be simpler and when you deal with flea-bay you never know whats going to show up on your doorstep. Good luck to you
You can use either the high level (speaker) or the low-level (RCA's) inputs to the amp, but not both. Choose whichever one sounds the best or is more convenient to install and leave the other disconnected.
There are two things. First check the sound settings of the DVD player. It might be putting out a lower quality sound on the CD side of things.
Secondly try to determine if the speaker tweeters are working. Connect the speakers if you can to another sound source. If the speakers are good and the settings fine. Then you have a fault in the amp unit.
