Question: Can i combine two amps to a dual 12'' subwoofer?

[scx 10+ year member]

I bought new dual 12'' subwoofers and they require a rms of 500watts (250w rms x2) but right now I only have a 250w rms amplifier. The new subs came with another amplifier they has similar specifications as my current amp. I was wondering if I can add this amp onto my car and run my subwoofers at optimal settings.

here are the parts i have

NEW CRUNCH P500.2 2/1 CHANNEL CAR AMPLIFIER AMP 500 W - eBay (item 390163383721 end time Mar-29-10 11:25:57 PDT)

this is already installed onto my car

and these are the new subs and amps i got

New Visonik 1000 Watt Dual 12 Inch Subwoofer Amp Combo : eBay Motors (item 120537524199 end time Mar-02-10 18:41:32 PST)

(i bought visoniks because I had a previous model of their brand they were pretty good for the amount I paid for)

by the way, i'm new to car audio and I've been trying to do research. Does anyone have any sites that I can read up on? It took hell of a long time to understand RMS and peak wattage.

thanks!

you can put an amp for every coild.. but runnign 2 amps with diff powers is going to cause problems

Unless you get the same power to each coil you will have problems. Which would be a pain in the a@# even with 2 of the same amps unless you have a maxxlink. I wouldn't do it.

hook each coil (those subs are single 4ohm VC) to each channel on the amp. That will give you approx 125rms each. Should be loud enough. do not run two different amplifiers. If you want more power, sell both of your amps and purchase a new amp that is stable @ 2 ohms

thanks guys

I ended up using the crunch amplifier and i'm putting out 125 rms to each sub.

I plan on saving for a better amp that will really put these to potential.

I have a side question though

the thickness of the copper wire that i connected my subwoofers from the amp is different for each subwoofer. One set of speaker wire seems only a little thinner than the other. I was wondering if that would eventually cause problems too?

I also read up on different gauges of wires? Does that have anything to do with the wire that connects sub amp??

Use the same wire for each sub you will run into problems soon anyway =[

run the same size wire to each sub. why dont you stop mixing and matching, save some money, and buy the right stuff the first time

How would I get problems? Wouldn't it be fine as long as I don't go into clipping territory?

Well I originally had a perfectly functioning set before but my subs got jacked and before I lived back at home and had help with all this stuff. Thus the reason why i have different wires and stuff. What would be the right stuff?

A 2chan amp with 500rms watts? and same wires lool
