Rep Power: 291

won't really be any cheaper since that 500w will be 250w RMS x2 at 2ohms, so it will be 125w RMS x2 at 4ohms. you really only want to pay attention to RMS power. RMS means "Root Mean Square" it's basically a fancy term for "average". peak power doesn't mean much since probably less than 1% of the time will be spent in the peak power range.

the RMS power is the power from the amp. the 12 ohms is the internal resistance of the speakers. the RMS power is what's driving the subs. it's unit of measure is watts.

^^^ Again with the sage advice from electric130.

In all honesty you may be better off selling your box and speakers as-is for $40 and then putting that towards one 10 or 12" sub with a 4ohm resistance and a decent 2-channel amp. It would probably be much cheaper to go that route, than to try and find a decent, reasonably priced amp that will push enough power to sound good on your 6-ohm setup. Hell even one, newer, 10" sub with two 4-ohm voice coils (aka DVC) and an amp will be cheaper and probably sound better than what you've got now.

Think of it this way. You've got an old Pentium 3 computer and you are trying to play Doom 2, or NFS Carbon. You can do it with your existing setup - kind of - but you'll have to pay through the nose because you're mixing old and new techonology to get the same result that eMachines sells for half the cost.

Make sense?

i got my 2 kicker comp 12's from CircuitCity when they had buy one get one free, so i paid $100 for 2 brand new kicker 12's.

This thread is turning out to be quite the guide for sound audio advice. Im not sure if you are still deciding what to do or not, but if I was you, I would try and get rid of your current 12 ohm subs and pick up a single 12 or a single very good 10 (JL, RE, Adire, etc). The fact of the matter is, our cars are tiny and dont require much to be "too loud." My single 12 in a sealed box hurts my ears if I turn it up too loud. Nowadays you can pick up a cheap 12" sub, box, and amp for around 200 all together on sale from somewhere, and it would be much less of a headache. Dont get me wrong, you can go ahead with your proposed setup and be able to drive it with almost any amp that has a lower amp rating, but I think youd be very happy with a single 10 or 12 driven with a mopderate amount of power at 2 or 4ohms.

I have two of these:

Kenwood eXcelon KFC-XW1202DVC


Which have these specs:

Dual 2 ohm Voice Coils
1200w Max Power
Dual 2 ohm Voice Coils
93dB Sensitivity
20Hz-400Hz Freq Response

And they hit damn hard, and can literally shake the windows in the house from my outdoor garage when the door is down, if I crank it. Its obscene. Now I'm running them both off this:

Kenwood KAC-7201

Which has these specs:

Amplifier Type: 2-channel
RMS Power @ 4 Ohms: 150W x 2 @ 14.4V
THD at 4-Ohm RMS Power: 0.08 %
Bridged RMS Power @ 4 Ohms: 460W x 1 @ 14.4V

So, I've got the VCs on each run in series for 4ohm load on each sub. Which tells me I am NOT running an optimal setup for what I have. I am going to get rid of one my 12s, but still run the VCs in series for the 4 ohm load and bridge the amp (that's all my amp can take bridged). With that config, one 12 will probably hit a helluva lot harder than both of them - on my current setup. That's a project for when I get back.

Just for a reference, and also to show that a less than optimal setup can still work.

ditto. same thing with my single 12" Kicker Comp. I'm running it at 180w RMS and it's more than enough. other people that have ridden with me swear that i've got at least 2 subs. it doesn't take much.

Man, I had a little 10" Kicker Comp in my old CRX (87 with the 3 .bbl carb!!), and I loved that sub! I think I was pushing maybe 120-130 watts RMS to it off this old Sherwood 4-channel (other 2 chans were pushing my WalMart 6x9s). What a great sounding sub! I'm sure the 12" you've got is the same way. I'd be running Kickers this time again, but got a great deal on those Kenwoods.

Well with all this info, I think I might just sell the ones I got and invest in 1 or 2 new subs. Seeing as how you guys think one will sound alright, I'm starting to think I might just throw one in there... couldn't hurt. I'm off of work today, so I'm checking out circuit city to see if they've got a bitchin' deal like electric got.


I'm actually quite suprised at how well this thread turned out myself. A LOT of good info for all the beginners like myself. Keep the good shi+ coming.

**** or get off the pot man! Although with this much procrastinating, I'll be home before you make a decision, have a box built for one 12" sub and have an extra to sell.

you are looking for something like this?

The subs are 2 10" clarion subs powered by a 1000w mono block amp. I made the boxes myself, and I posted plans on the second page of the thread. the boxes are 1 ft of cubic space +/- a couple inches. they are covered with felt i got from wal-mart.

what kind of amp is it and how may watts is it...for the record a amp can say its 1000watts but it could only be like 275 max. i know it doesnt make sence but its true. i have a 1000 watt crossfire amp and im pushing 1500 watts out of it. 4 guage is always good 0 guage is really for alot of power i recommend 4 guage. tell me what kind of system u have and ill tell u exactly what to do. give me the make and model of subs and amp
