my question is should i get a bigger amp or would it be too much drain on the alternator? if not will it be enough to run the good bass?

[o4aveohb]

500 watts if fine, you might need a capacitor if you go any higher, I had a 400 watt then a 600 watt and it was fine.

[Aussie BarinaTK]

yea i was tryna find a 400watt but no good. wots the benefit of goin higher? is there ne real gains (i kno this is a newb question so dont beat me for it!)

[deniswhite1]

ok, the deck is fine, but your choice of amp and sub is not and here is why:

when your are buying a sub you need to look at watts RMS not max watts (max watts is never achived and its complitly false to go by max numbers) the sub you posted is no way in hell 1000 watts RMS, for a refrence here is mine 400 watt RMS 10" mtx sub
,
its a tank, do not buy any of thouse noname subs you will be very desapointed. get your self a 1 10" or 12" of a brand name such as mtx, rockford fosgate, kicker or JL, again look at watts RMS ratinginsted of max ratings, you will want something around 300-400 watts rms handling for a sub.

as for your amp here are the real specs
o OUTPUT POWER (MAX): 800 Watts (400W X 2 @ 4 Ohms)

o OUTPUT POWER (RMS): 80 Watts (40W X 2 @ 4 Ohms, <0.08%)o OUTPUT POWER BRIDGED (MAX): 800 Watts (800W X 1@ 4 Ohms)

so this amp will only give you 40 watts rms on full blast per ch, so when you bridge it you will be lucky to see 50-60 watts RMS going to your sub with music, or 80 watts rms when you are playing test tones (but you will never going to be doing that).

this is a horible amp, like i said go for something brand name like mtx, rockford fosgate, jl or kicker.
brand names such as rockford fosgate underrate there staff (my 2 ch 450.2 is rated at 450 watts RMS, but inreality is a bit over 500 watts RMS)

tell me what size sub you want how much power you want to put in to it and i will tell ya what subs and amps to look at.

is this guna give me what im lookin for? sry for bein a noob!

[deniswhite1]

i have that exact sub in my room, its very good, but you need a amp with at list 200 watts RMS

[AveoRob]

Thank you Denniswhite for correcting the MAX vs. RMS watts. I love when people talk about peak watts, always always use RMS

[Aussie BarinaTK]

is there a formula or something to help work out the rms from the max power? or is there no way to tell from max power?

[deniswhite1]

in short NO, with subs you can assume that rms will be half of max (not always true), but with amps you can't. if you get an amp from a reputable company the will have a rms rating, some companis don't even post max watts because thouse numbers don't meen ****.

is there an amp your looking at?

[petrified.rabbit]

this might sound stupid, but its the 09 dash simply a true double din? it looks a little wider at the top that the bottom but that might just be the angle. i was thinking about installing a head unit like yours but if it requires a small filler piece to fit the gap i would just buy an upgraded OWM off ebay.
