ok i hqave a 2 channel amp. and 2 10" subwoofers at 400 watts my amp can do 480 watts at 2 ohm.

Q: do you add the 400 watts x 2 = 800 watts or is it just 2 =400 watts subwoofers. im not sure wich! do i wire it mono or do i wire it like 1 channel for 1 sub and the other channel for the other sub. the subwoofers are DVC type

Amp

Alphasonik cha150

Subwoofer

Alphasonik psw410

2nd Q:

i have a volt meter and a bass volum control both of wich have a rj11 type connector. but its not a rj11. they are smaller. i have contacted alphasonik. but they couldnt tell me what type .. they did say its a tiffny style.4 wire .. i have chwecked at radio shack . no luck..

thanks in advance steve

Are you sure about the model # on the amp?? I can't find anything on it.

As for your speakers, they are both 4ohm DVC's so you can either wire each sub to be 2ohms or 8 ohms, then connecting both to 1 ch of the amp you will either get a 4ohm load or a 1 ohm load.

Can your amp handle a 1 ohm load?

What are the specs on it is it 1ch, 2ch?? is the 480w @ 2ohms per channel or for a single bridged channel?

at a 2 ohm load your amp will produce 480 watts x1 mono, if you run one channel to one sub and one to the other, you will be getting 240 watts to EACH sub at 4 ohms. just make sure you wire your subs paralell if you go to 2ohms :)

and also .. to get the most out of this amp. wiring it paralell is this both coils wired mono?. coz im really wanting to get the full 480 watts. to both sub. more power .. hehe i just dont want to be under watts. coz i think that would be bad too right?i may end up buying another amp. i would like to see 400 watts to each speaker. thanks in advance

yes, wire the positive from the amp to the positive of one voice coil on one sub , and then to the positive of the same voice coil on the other sub. do the same with the negative, from amp to one vc then to the other vc. that will give you a 2 ohm load = 480watts to each sub = getting the most out of your amp.

Well if yours is right below this one then I am guessing yours would run the following:

75x2 @ 4ohms Stereo; 135x2 @ 2ohms Stereo; 225x2 @ 1ohm Stereo; 292 x1 @ 4ohms Mono; 480x1 @ 2ohms Mono; 550x1 @ 1ohm Mono

I would run both the subs @ 2ohms, which is done by hooking both + terminals on each speaker together and both - terminals on each speaker together, then run both speakers parallel to the amp to give you a 1ohm load on a mono channel.

how would that give you a 1 ohm load? he has dual 4 ohm voice coils, parallel would be 2 ohms.

Simple Math lol

He has 2 4ohm DVC subs, so you are looking at a total of 4 4ohm coils, 2 per speaker.

If you wire the 2 4ohm coils on speaker 1 in parallel, and the 2 4ohm coils on speaker 2 in parallel, you will now have 2 2ohm speakers. If you run both speakers in parallel to the amp you now have a 1ohm load on the amp, this would get the max power out of the amp.
