Help with 5 channel amp

[na_rsx 10+ year member]

Okay, i just picked up the Kicker KX700.5 for pretty cheap, its beat up but works. When i checked the specs, i get different answers. My main question is this, can i run the 4 channels in 4 ohms, and the sub in 2 ohms? i dont have the pretty case, just the amp.

Yes.

Yes.

thanks, all i need to know, because i have 2 cheap single 4 ohm voice coil subs, and i wanted to wire them into 2 ohms, and run the other 4 speakers regularly at 4 ohms.

imaginary +rep to you

I think you'll be happy with that amp. If I was going to buy a 5 channel, it'd likely be a Kicker.

Specs indicate:

400 x 1 at 2 ohms

so yes

oh i know that, but can it do both at the same time, 4 ohm for the highs, and 2 ohms for the sub, but DejaWiz already said yes.

There were some reports of people running those at 1ohm but I wouldn't recommend it. Make sure you have a healthy wiring/charging system. That amp will pull some power, at least mine did when I had it.

It is stable running like that and shouldn't give you any problems...//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Tough amplifier. I used one in Jeep Wrangler for 2 years. Dirt, mud, morning dew, some rain, basically an outdoor environment. Never missed a beat.

wow, thats good to hear, this amp is really beat up externally, but powers up like a champ. i need to test the other channels though, only tested the sub.

ok, i am thinking about running some coaxials in front and rear, 6 1/2 front, 6x9 rear, but when i see the specs, how can i run these coaxials in 2 ohm when they are single vc.

# 40 watts x 4 + 200 watts x 1 RMS at 4 ohms

# 150 watts x 2 + 200 x 1 bridged power

# 75 watts x 4 + 400 x 1 at 2 ohms

or am i better off forgetting about the rear fill, and get a decent set of components in the front, and just bridging it.

if the sub channel is running at 2 ohms, does that mean the speakers are doing the same, this is the thing that confuses me //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Just think of it as two amps in one shell. The subwoofer channel can be run at any impedance you want (well as long as it's supported) independently of the other channels.

you shouldn't have any problem running the subwoofer channel at 2 ohms and bridging the other channels, or running the sub channel at 4 ohms and running the other channels normally at 4 ohms.

got that, but for the 4 channel portion, how can i run all 4 speakers @ 2 ohms when they single 4 ohm voice coils. i would love to have 75 watts going to each coaxial speaker, instead of 40 watts. well i guess i am better off getting a good component set, and run them bridged.

thanks for the help everyone, i hate not knowing these kind of things.
