Systems

ok i got 2 10inch polk gnx woofers hooked to a 350 watt kenwood amp.it pushes 60x2 at 4ohm.and i was lookin on crutchfield at alpine amps and there is a alpine v12 that puts out 110x2 at 4 ohm and 170x2 at 2 ohm.the woofers recomeded power is 175.its a 4ohm woofer but if i wire them together there 2 ohm so i was thinkin of wirein them so there 2 ohm and have 170 watts goin to em??is that a good idea or should i get a amp that puts 170x2 at 4 ohm??i got a alpine indash and i love it so thats why i want a alpine amp.thanks for the help

Actually no, if you wire the subs together in parallel, you'll get a 2 ohm MONO load. The Alpine amp you're talking about is a 2 ohm STEREO load. That amp won't work. In fact, most two channel amps won't work for a pair of 4 ohm subs, unless for some reason you wanna run the amp at 4 ohm stereo. If you really want a V-12 amp, look at the MRD-300 or the MRD-500 monoblock amps. They will do a 2 ohm mono load which is what you need for maximum output from the amp. The 300 will give you 150 watts+ for the each sub while the 500 will give you 250+ each. You'd probably be better off with the 500. I'm not sure how well these subs take the power, but I'm sure you'd be well suited with the MRD-500.

Pretty much no matter what you get you'd want to get a class D monoblock amp to get the 2 ohm load.

thx for the help

THE TENS HAVE THE SAME SPECS AS THE 12'S DO...THAT BEING SAID I HAVE 2 PLKGNX124 SVC'S AND THE ROCKFORD FOSGATE 351M IS A PERFECT MATCH.....YOU CAN GET IT OFF OF ETRONICS.COM FOR 139....AND IF YOU WANT AN AUTHORIZED DEALER SOUNDDOMAIN.COM MATCHES PRICES IN MOST CASES....IF THEY HAVE IT

YOU DON'T NEED TO YELL

shhhhhhhh......

yea its a perfect match for 1 sub i got 2.is there anyway you could wire 2 subs that are 4ohm and keep em 4 ohm????

C-Man

Sure, add 2 more 4 ohm subs. You can't wire two 4 ohm subs to equal 4 ohms mono, it will either be 2 or 8 ohms.

that or get a sepate amp for each sub...thats what i have...2 2 channel rockfords...1 for each mm12

so if i buy 2 more 4ohm subs i could hook all 4 up to the rockford 351m amp and it would power 4 4ohm subs and still sound good??

startzy - u got it bassasswards...

the Rockford 351M does like 175 x 1 at 4 ohms, and 350 x 1 at 2 ohms.

the two subs you have wired in parallel, will be a 2 ohm load.

thus, you'll get 350 x 1 to that load, each sub will get half of that 350 (350 / 2 = 175) ... which is 175 a sub... thats what you want.

ah cool i finnaly understand.thx for all the help guys.
