my question here is if i get two 12's in the back what would be the best way to power them? with a 2 way amp or 2 mono amps? i was just wondering if it would hit harder or get better sound having mono amps instead of a 2 way amp to power subs.

 

If you got the money to buy two good quality mono amps, gor for it. If you don't, then buy only one very good amp that will shell out enough power

 

i would go with one amp. saves money, and doesnt make a huge difference. spend the money on a good jl audio amp...those will push out maximum power at any volts.

 

A single mono amp can power 2 subs. Depending on what you're doing, this is probably the way to go.

Which subs are you trying to push?
Is this a comp setup, or just for banging around town?

 

also, what is the impedance of these subs?

i would suggest doing some research into car audio setups and wiring so you can become familiar with how everything works. it'll make it a lot easier and more interesting when comes time to install.

 

ya also if u give us a price im sure some of us could find you a decent prices for each part on the web

 

so as for a set up i just want something that bangs. so i am looking in the near future to get the subs and amp setup. so i was either thinking about getting like two 12's or if it would be better just to get one sub and a mono amp like a 15 inch sub just want a bounce not looking for much compitition so as far as money goes im trying to get an alpine deck right now hoping to get a 9815 or 9813 but see what my budget can support. just wondering how much the setup i was just talking about would run me?

 

Heres the deal though... A lot of people forget this. The overall loudness of two subs, each taking, say, 150watts of a 300watt rms amp will be IDENTICAL to 1 sub taking the full 300. If you're not buying one huge amp, then just get one sub. Otherwise, either get a really powerful amp, or two average ones for two subs.

 

Uh... how much would what setup run you... all I see is 2 12"s or 1 15" that puts you anywhere from $50 to $2000 in drivers, and $100 to $5000+ in amps.

How about you give us a price range to work with?

 

actually, if you double the surface area, you are doubling the loudness, which equates to a 3dB gain. but there are other factors involved too...

 

well in all total just only for my headunit, subs, amp and everything in between i think i dont want to exceed 600. so im looking at getting an alpine 7995 deck but it can change, im bidding on a sony mono amp not very powerful but just a good deal its a xm-d400p5, i was looking to get maybe a 15 inch woofer from sony also for like 90 bucks. then i dont know what everything else costs so like wiring .. i can put the deck in myself but to wire the amp and everything i think i might get ryancb to help me out there.

 

so now my question is that if i do get two mono amps how do you wire it up. i just bought a alpine 9813 headunit and it has three rca pre outs for amps and one of them is for a sub. and if any of you know a good place for me too look up just audio setups let me know!

 

i can do it just call me on my cell or drop by u know where i live dude, youl laugh at how easy it is

 

yo... 98-13 is a cool deck =D

i have a full alpine system

alpine 9815 with two alpine v12 amps , 1 4 channel and one 2/1 channel for the sub... and two alpine 10inch type=-s subs =D

with the wiring on those .. what u would most likely do is run separate power lines to each amp... some peopel use one and splice off of the second amp but i heard its not gret like that .. u can lose power or somethign... with the rca pre-outs, u can either get a rca splitter and split FROM THE DECK not at the end.. u get better stronger signal like that.. then connet to ur amps... or you can just run it from the sub pre out and the rear channel pre-out..your amp should have a low-pass crossover on it and that'll make it just the same... but you SHOULD get just one amp and power both.. its easier and will save u money
