these subs (2) either SVC or DVC

and maybe this amp
http://www.polkaudio.com/caraudio/produ ... /pa1200_1/

idkif i will get the amp because the most power i can make at the subs would be 400 with SVC

anyone have recomendations on a decent amp to power the subs??? there 700RMS

any input would be great

if you get SR104-DVC you can wire them to a final load of 1ohm and give each 600 with that amp.

yea i know that but will everything be stable at 1 ohm load? and everything will run warmer at 1 ohm

that is what the company states the amp will perform so if you have any worries be sure to buy from an authorized dealer and you should have no problems. also pay attention to the specifics of the warranty about things like installation. most electronic warranty policys state the items have to be installed by a professional to be valid.

i personally run cadence amps bought directly from cadence and probably will for the rest of my life. i had a problem with one and they repaired it under warranty and shipped it back to me, at no cost, with no questions. customer service is much more valuable than saving a few bucks from a discount web site.

does 600 x 1 @ 1ohm, so you could buy a set of 2ohm dvc subs and go to town. this is line line of amps i have and i love the power, and their ratings are 13.8v, not 14.4v.

if you are looking so save some cash you could always get a pair of

and then 4ohm dvc subs to end up with the same power. would be $100 cheaper total but i prefer the looks of the txa line. also, the txa line has all inputs and adjusters on the front panel whereas the sqa line has them on the sides. that is just a personal thing though.

idk i was hoping to run a single amp but i heard that i would need about 1800 watts with the 3/4 rule which says to take the RMS and divide by .75 thus giving u the total wattage of the amp i need if u understood correctly

so if i follow that rule you figure if i run them off one amp it would be 1400 RMS (700+700) / .75 = 1866.88 watts

or if i got 2 amps i would need them to be 1000 watts a piece 700 / .75 = 933.33 or 1000 watts

well, good luck with your search. i have never heard of your 3/4 rule but i can tell you that a cadence amp will do all it claims and more. 99% of amps are rated at 14.4 or higher, while the cadence are rated at 13.8 which is much more realistic for real life applications. i am not that familar with polk subs, so they may be under rated as well.

i currently run a txa-6004 to a pair of type-r subs and it is a match made in heaven.

im doin some research on the cadence.....and i got th 3/4 rule off the polk site when i was reading info on the subs

sounds like a marketing ploy to me.

keep in mind too anything under 2ohms the harmonic distortion goes way up. enough to notice

trinity_rush2001 · Post by **trinity_rush2001** » Fri Oct 17, 2008 7:31 pm

yea i think im gonna run 4 ohm

Craz1000 · Post by **Craz1000** » Sat Oct 18, 2008 7:44 pm

youll be better running 2ohms, theres almost no difference in THD with 4ohms and your going to get WAY more power out of the amp also.

your going to end up with the SVC's if you want 2ohms, if you want 4ohms your going to have to get the DVC's
