Hello, I just purchased a pair of Alpine Type-R 1221D's 2ohm subwoofers. I am having a friend build a calcualted box for the subs.


I realized that my Rockford Fosgate P3002 lacks the power to power these suckers.

Im willing to spend up to $400 for an amp, any recommendations?

these are the 1000w dual 2ohm right??

so yer looking at either 1 or 2 1000w x1 or x2 @4ohm or 1ohm (one channel/two amps or two channel amp) or 1 2000w x1 @ 2

two jbl 1200.1's with the gains down to half would be perfect for the job

I think these are ment to handle like 300wrms each?

I belive the ideal amp for those would be a JBL 600.1, prolly pick one up at your local jbl dealer or on ebay.

I think the guy doesnt like you marty cause you deleted his threads?

Whiplash

yuppers, yer right, my bad..
thought the jbl was rated for 1ohm..
600.1'll do 600@2
1200.1 is 1200@2 (more like 1400 anyway )

heh, he ain't the first to hate me, won't be the last....
dunna wanna follow the rules ya lose yer priveledges.....meh

JBL really the best brand to go with?

I was thinking of maybe going Audiobahn

Whiplash

well i like the baun!!!
'spensive tho....

jbl is a great amp for the money, should be able to get a 600.1 used for around the $200 mark

lemme check "the bible" on the baun stuff...

6004t intake series

get ready to spend on the following list:
2300hct high current
2150hct high current
1300 hct high current

the real good stuff:
1502dp digital (i have one of these so far..)

the rest ya get into Dclass and Rack Mount..

AggressiveAdam

Should I buy the older

1200.1
or go for the 1201.1

or should I go with the 600.1?

scarlemthug

get yourself a used 600.1 and you will be more than happy, IMO that series of jbl's are the best bang for buck.

Whiplash

ya 600.1, you should see around 700w easy outta that baby..

AggressiveAdam

whats the diff between the 600.1 and the 601.1
