i think that amp would be good to power some coxial speakers or components, but not subs... i would recommend something bigger for pushing subs

Probably not the best amp to run subs off of.... Maybe one really low powered sub like an Re12 or JL 12 W0...

it will power speakers way better than any sort of low-frequency larger speaker.

its only "170 rms" and i wouldnt give it that much.

i will be giving 150rms to each of my midbass speakers. consider a different amp. but for shits and giggles - it will power ONE single 4ohm sub that is VERY entry level, or a better SVC4 sub that is infinte baffle //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

170W is more than enough for a single JL Audio 10W0.

oh ok thanx for your help.. i'm just a beginner and i don't really know wat to get..but i will try this first. can i use this with lightning audio P3.10.4 model which has an rms of 150? Is this brand a good one? Can u suggest to me some more subs that is compatible with this amp..thanx

If you can wire the sub to 4 ohms, then yes it would work. Neither dual nor lightning audio are considered to be good brands.

you could get an Infinity 1030W...yea its 250WRMS but 170W will do just fine..I had my 12VQ with 100W and it pounded and sounded amazing..

 

[magtatahochi]

thanks a lot for ur help..another question. can i possibly use two 150 watts rms subs with these amp?

If you *really* wanted to use this amp, a very efficient enclosure could be used, like a folded horn or transmission line. Then, I bet you'd surprise people very well with "only" 170W //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 

[magtatahochi]

how do i do these folded horn and transmission line? can i possibly use this in two 150 watts rms or 200 watts rms?
