amp to sub circuit question

jimmy_beaner · **amp to sub circuit question**

ok, can I have them hooked up in parallel like this? 2 subs off a single channel amp? It would level out the power, as the subs I want are 2 kicker L7's, they're 4 ohm each. Now, putting them in parallel would make them appear to the amp as 2 ohms. Would this affect anything? Each sub has 750 watts RMS, and 1500 max watts. It's a dual voice coil sub. also, what power rating am I looking for for the amp? I think this could be a good easy way to save some money.

You would have to tell me that amp model first.

I don't know... it was sort of a theoretical question. I haven't bought the amp yet. I'm lookin' for suggestions. Just didn't know the wattage I would need the amp to have, or if you can even do a signal split like that.

**Brent** · **Re: amp to sub circuit question**

Yes you can wire it in parellel and it will see a 2ohm load. Just make sure the amp can handle a 2ohm load... all mono block amps will.

ok, but what specs am I looking for on that amp? could someone give me a link to one? I want to utilize close to the max of what the subs can do.... but not enough to blow them.
also, will the fact that they're being seen as a 2 ohm load change the sub output any, because they're a 4 ohm sub? Or will each see current as though they were 4 ohm instead of 2?

just run 2 amps or get a monster 2 ch amp, it will be alot easier and remember that a mono block to two subs will cut its power in half

PS run the ohm load the SUBS are made to run at

jimmy_beaner · **Re: amp to sub circuit question**

the only problem is that it's hard to find amps that run 1500 watts at 4 ohms. hhhhhhhhheeeeeeelppp me.

Or you could just buy one amp and run it at 1ohm.

It won't be easier or cheaper. Buy a Mono amp that can run at 1ohm.. there are plenty out there for what you buy two amps for.

That makes no sense. The subs can run at different ohms.

You got 2 dual 4 ohm subs. This mean you can buy a mono block amp that is 1 ohm stable and wire the subs to see a 1 ohm load like this:

I would recommend this amp:

eBay: ***Directed 1100D Mono AMP**Like NEW*** (item 9722209806 end time May-11-06 12:35:39 PDT)

1000x1rms at 1 ohm. Plenty power

jimmy_beaner · **Re: amp to sub circuit question**

thanks a lot Brent. Now, here's my question. Will each sub hit with 1000 watts of power? Or will it be different than that?.. and OMG, 1000 watts RMS, that might be too much, hahaha... the subs can only do 750 watts RMS. Guess I might have to tune it down? Or would each see 550 watts RMS?

Each sub would see 500rms. Plenty imo.

funny because thats exactly what i said but i was wrong

anyways have fun getting the subs to run safe at 1 ohm, subs are made to run at the ohm load that they are made to run at for a reason, some can do it some can't. but whatever

yeah, you're right, at least for now, muhahaha... yeah, gotta get the Saleen first.

You said get a Monster 2 channel amp

Monster 2 channel amps don't go to 1ohm stable. A few mono block amps do. Monster 2 channel amps also do not have sub sonic filters and are not as efficent. I have never seen a sub that couldn't do 1 ohm stable. Especially a Kicker L7 that was designed to push out serious bass.

jimmy_beaner · **Re: amp to sub circuit question**

yes, I am going to love the L7's

.... serious bass = a happy Beaner

Just to warn you, you will most likely want a cap so you don't kill your alty. I went through 3 alty's in my old car in a year, and I had 2 bd1000.1 fosgate power amps on 2 12" power HX2's. Once I got a cap for it, they hit like they never did before. That..and the other good part about a big system, you can always turn the bass down a few notches, you can't turn a small system up a few notches lol.
With that said, I'm enjoying my 600rms to 2 dvc premier 12's.

I will definitely have a capacitor... what size would be best?
