will my current amp power a 13w7?

Question, Will my current amp work for a upgrade in drivers.

Car is a 2000 vw golf , electrial upgrades would include a yellow top upfront and 4 guage stinger amp kit to my sub amp. Alt is still stock and still need to do the big 3 but soon,

Amp is a Alpine MRP-M1000 Is currently powering a type R 15 but i want to change it to a 13w7

Would this set up in sealed box be enough to power the sub ? will trade up in amps if i have to but with such a small car the cabin gain should be pretty good right?

If this amp puts out 1000@ 2 and 600 @ 4 ohm does that mean a driver drawing a 3 ohm load would pull around 800? i have no idea about that just asking and if so would that 800 be enough to push the w7 to what it should do sealed? I have heard them sealed in good set ups and think they sound a lot nicer than my type r.

you would have to do a 3 ohm impedance and would only get like 800rms assuming your voltage stays at 14.4v

thats what i was thinking,

800 rms is 80 % of the optimal power Jl audio lists but do any people here with real world use of this sub have input please? from my listening it sounded way smooth sealed than my sub but it was getting powerd by a 1000.1 v2

i put 2 12s in somebodys suv....i wouldn't seal this woofer imo ...................but we also had it powered by a fosgate t25001 each getting about 1300rms took it like a champ.

im thinking you would be happier with a 13 w6 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif...........ill do $330 shipped to canada if you do it today...............pretty sure its alot louder than you think it is.

apples to oranges , a single sub set up in a hatchback vs dual 12''s in a suv,,,,why would you not seal them other than the output loss?

ya i thought they would do a little over 1000 , cool good to know if i trade up amps later

getting a great price on a great shape 13w7 sorry man

well the 13 can handle 1500rms +...............since you only plan on running one i would port it and tune it low should be happier with it. unless you plan on running a straight sq set up.
