After getting new speakers all round in my cab, it still lacks in BASS big time!! So after reading threads on other peoples installs, ive decided to go for alpine Alpine Type Rs. Not One but Two 12" Type R subs!

Specs:
#
1,500 WATTS TOTAL OUTPUT per sub
# 500 watts RMS per sub
# Frequency Response: 23 Hz - 500 Hz
# Sensitivity: 87 dB
# Dual 2 Ohm Voice Coil Version
# Mounting Depth: 8"
# Sealed Box Volume: 0.7 - 1.0 cubic ft
# Ported Box Volume: 0.75 - 1.75 cubic ft
# Kevlar re-enforced Pulp Fiber Cone Assembly
# Santo-prene Rubber surround material stops un-wanted vibration noises and ensure clean sound
# Dual Voice Coil Design
# Cast Aluminum Frame
# This sub is vented and transfers the heat out of the sub so it stays cool at all times
# Concealed Mounting Gasket System Frequency Response: 24 Hz - 500 Hz

Next on the list is an enlosure to house the subwoofers! i dont want to go down the DIY route as i havnt a clue how and if i try, i would make a complete and utter mess!!

I found this ready made enclosure which is 12" Twin Bass Box 2 x 1.0 Cubic.Ft, Clicky

Do i go for sealed or ported? (whats the difference?)

Next is Amplifiers!

Any recommendations?
Should i power 2 subs off a one mono amp? (or 2 mono amps? )
Or off a 2 channel amp?
Do i go for highest watts i can afford and just turn it down so not to blow the subs
or go according to the power the subs can handle?
Any brands in particular!? I havent really got a price limit!!

I have just been given a 4 channel kenwood amp from my bro which i will use to power the front components and rear speakers.

Sound proofing...

Does it make a difference?
what do i go for, is dynomat extreme the best?

will be looking forward your opinions!

Thanks you!

Saq.

I havent really got a price limit!!

I had 3 of the type r's in my old car, they are good, but as you have no price limit, i would suggest 2 JL W7's instead, i switched to these and the difference was unreal.

One mono amp will be fine for 2 subs, they come with instructions and wiring diagrams. I would recomment a JL 1000/1 amp, i had one and it was absolutely amazing!

Sound proofing - yes, lots!

Aww man ive already purchased the subs off ebay!!
I think ill have to make do with the type Rs for now!

And ill have to look in to that amp, thanks for your input

try alpine v12 amps, you'll be sticking with same brand and apparetly they deliver lots of power at a high quality, plus they have a useful table on the alpine site so you can match up to the subs you have.




hope this helps, i like alpine stuff...can you tell

Dont get me wrong, they are really good subs and im sure you will be pleased. I had them for about a year before i decided i wanted something a bit deeper. Good luck with it all mate

+1

Can't fault the stuff
Well worth the £Â£Ã‚£Ã‚£ IMO

Alpine Subwoofers are excellent for the cash.

I personally prefer the sound of the Type-L's in 10" to any other of theirs.

Ive heard V12 amps are amazing! ive looked on the alpine site and its now suited to the type r though

Thanks m3ben05, im sure i will be pleased with them, but i know i will want more after a few weeks!

One more Question, is it a good idea to get a power capacitator (sp) do i need one ?
