Can I wire three 10's like this? (need help ASAP)

[aRE? 10+ year member]

Would this work?

2-channel Nakamichi PA-1002 bridged to 200W x1 @ 4 ohms + three (3) single-coil 100W 10-inch subs @ 8 ohms (each) wired in parallel. What size fuse should I get?

nope

go +from amp to + on all subs

go -from amp to - on all subs

=

2.67ohms at the amp make sure its 2 ohm stable amp

thoughs 3 subs wired in parallel will be 2.67ohms at the amp bro

fuse depends on gauge of your power lead and the current draw to amp, i would have 4g lead with atleast a 100amp fuse.

btw someone lied to you cuz that amp is 50watts @4ohms and 100watts @2ohms

bridge it to 1 channel and run it parallel to amp that will be 100watts@2ohms

I'm a dork. So I need a mono amp that does at least 2 ohms? What if I do the subs in series?

you cant run 3 8ohm subs in series, and bridge your amp to 1 channel (first lead and last lead) it will run the subs at 100watts@2ohms

That is the dcr, actual to the amp with rise will be close to 4 ohm.

24 ohms? do you already have the amp?

Ummmmm actually you could......3 in series is 24 ohms....divided in half means the amp will see 12 ohms.

i no you COULD but he dosent need to do that, he has a little front stage amp he is trying to run 3 subs off of, he is already gonna wind up blowing his amp lol...

Yes, I have amp and subs. Just want this to work somehow.

What's DCR? The amp will also do 100W @ 8 ohms bridged.

 

[CHEMMINS 10+ year member]

DCR is what your subs will measure, not moving......once amp is fired up and subs are moving, you will get what is called box rise. the impedance rises due to various factors. A 2.xx dcr will rise to over 4 making it safe for your amp.

I have pondered this and think I came up with a solution that works.

What if I run the amp in stereo and run one channel to two (2) subs in parallel, and then the other one through the remaining channel. This would effectively be 4 ohms, right? I know the load will be different between the two channels, but that's no biggie? Can I adjust the gain between the two?

There's not much point in trying to run 3 subs off of ~100 watts. You really should look into getting a ~500-1500 watt class D mono amp, or if you want great SQ, stick with one of the larger class A/B amps that can be bridged to 2 ohms stable.

Its always better to have too much power than too little. Having extra power on tap is good for headroom and also keeps you from taxing your amp by running it full power all the time.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

You should sell the amp you have and buy a new one, or you could just use two subs.
