amp bridge
ok guys i have a kenwood kac-7204 amp, and a ts-w257D4 pioneer sub. starting a week ago fuses started poping so i took it to best buy they said that the amp dose not go with the sub thats why(something about omhs, and i dont have a clue)
so since my amp is bridgable can i bridge it with my 2 back speakers they are upgraded to pioneers the modle is ts-a6881r. Will that fix the problem
here are the links thanks!

RE: amp bridge
well they are almost right(this is normally the case for worst lie), let me see if I can fill in the blanks for you.
The ohms ratings technical name is impedence. This is a measure that is used to see how much current or signal the speaker will "impede" the signal. Is measured in ohms and a larger ohms rating(4 ohm we'll say)will block a little more of the signal then a smaller ohms rating will(2 ohms lets say). When you put a speaker with a smaller ohms rating in this will cause your amp to send more juice(or audio signal) to that speaker, which will make the amp run harder and hotter. Now your amp has a couple of different ratings on it depending on which speaker and how many you use. The sub you have being DVC allows for a couple of different wiring options to allow you to match the sub to the amp, and get the most out of the two. A dual voice coil sub basically has two motors inside of it, both rated the same 4 ohms. You can wire these in two ways eitherseries or paralles to make the amp see either a 2, or8 ohm load per speaker(NEVER RUN ONLY ONE COIL IN A DVC SPEAKER!).
Now your amp is rated at 250 watts x 2 channels @ 2 ohms. If you have two subs, I would wire each of the coils togetherin parallel on each speaker to make the amp see both subs at 2 ohms, and send 250 watts to each speaker. parallel wiring is the easiest where you will connect the +'s and -'s together.
If you only have one sub, I would wire one side to one coil, and the other side to the other coil so that you amp will see a 4 ohm load on each output and it would then send 125watts to each coil, or again 250watts total to the speaker.

Could you elaborate in more detail about running parallels? Especially where the + and -'s go. I have one sub, in the future thinking about replacing it with one that is dual voice with 2 or 4 ohms, 400 max rms (the 12" kicker cvr), powered by a profile amp that puts out 500 rms at 2 ohms, 310 at 4. Whats the difference with running it parallel?

RE: amp bridge
well i only have that one sub and i think it is wired the way you said but if i play a song with ALOT of bass the fuse on the back of the amp pops
and my question was can i wire the amp to my back speakers to even everything out?
thanks
