Question about Alpine Type-R SWR-1242D Car Subwoofer

1 Answer

What would be a good amplifier for my alpine type r 1242? i already have a kicker kx 120.2 bridge, so its pushing 120 rms, and let me tell you it hits hard, but the sub wants more, its 500 rms, so what amp should i get, would a ultra linear 502 be ok?

What size amp do i need to run 4 1000 watt pyle 10's bridged


well first of all you cant bridge subs... you can bridge an amp... and for 2 they are probablly not 1000 watts, make sure you understand RMS and what the sub can ACTUALLY HANDLE properly... i would get a 1000 to 1500 watt RMS that is RMS RMS RMS RMS amp not one that says 2000 watts MAX POWER cuz thats cheap ****... get a kicker JL hifonic alpine or something in that category that actually tells you the TRUE power output of the amp... then run those 4 subs in a parallel circuit so its like really only having 2 subs. make sure then these subs do not run less then 2 ohms at the terminals while in a parallel, then bridge these subs acting as 2 subs not 4 to your TRUE 1000 watt amp and you should have a good powerful system

Will this amp power two 12" subs?


Yes. The Kicker xs50 competition amp will l ! Pushs my old school autobahn aw1206t's very nicely and beats my 2 sundown sa15's senseless. Wire down to 1 ohm and bridge. People may say yeah rite. Ok. Thats ok.

Got a 12"kicker L74ohm sub and sony xm-D9001GTR mono amp


Hello juan_penaloz,

The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.

You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.

Hope this helps.

Installing two amps


No, thats what you don't what to do. Even if you have 2 matching amps you don't do that. Every amp puts out different, and for 2 subs, you want to play at the the same time. If your only running 2 10's, I personal would just run the alpine (it's a mono amp made especially for subs) thats plenty for what you have. make sure you bridge them to get the full response. And your other amp i would use for your highs or mids, but run it @ stereo , which is 300 w @ 4 ohms. (Note: 600w @ 2ohms would be bridged and would play in Mono)

Building Competition stereo's is a big hobby of mine.

What is best amp to run 2 12 inch cvr's


12In Kicker CVRs
are Dual Voice Coil, and You can run each voice coil around 200 Watts RMS

So each sub will have a 400 Watt RMS and 800 Watts peak.

Now since you have 2, Your total will be 800 Watts RMS and 1600 Watts Peak.

I would get really any amp that sits at around 800-1000 Watts RMS.

These are kicker but they are low end so i wouldnt push them to the extreme.

1000-1200 Watts RMS Max and but keep the Gain down on the amp. They will hit no doubt but i wouldnt push these subs or you will be disapointed in the long run.

I would get a Fosgate or MTX amp.

You can get any amp really but find something right around 1000 Watts RMS and it will push those well.

You can go mono block or a 2 channel, just depends on how you want to wire them.

Be careful though. If your running them bridged right now with your mono block, do not run them parallel bridged on a 1000w RMS Amp, you will blow them so fast lol

(RMS = Root Mean Square. Or in other words is the continuous wattage being sent from the amplifier to the subwoffers)

Hi Gott Mudd,

 

I can relate to feeling it in the bones. You got the stuff to do it.  You should try the Alpine MP3 head units with bass boost, those are bad to the bone.

 

Wiring: 

 

Amp to Speaker I like to use the code VC for Voice coil, and AO for Amplifier output.  Also + for positive.  If I say VC1-, I am referring to the first connector starting left to right on the Alpine Sub. Now I have not seen a Kicker KX1200.1 amplifier.  All I see are MRA, MRP, or PDX prefix on the part numbers. So take what I am saying as a guess. You may want to revisit looking at the model of the amp to be sure your giving the right information.

 

We are going for  2 Ohms. Paralleling the two subs, not the voice coils. The voice coils will be series.  Bridge the amp if necessary to get mono channel. only using AO+ and AO- for output.

 

AO+ to Sub1VC1+

AO+ to Sub2VC1+

Sub1VC1- to Sub1VC2+

Sub2VC1- to Sub2VC2+

AO- to Sub1VC2-

AO- to Sub2VC2- 

 

Set your Crossover to LPF

Adjust the bass gain down to lowest until you test.

Set the Frequencies to midrange between 40 and 100hz  

 

Your box can be ported or not. It depends on the space your have.  If you do not have much room, go Enclosed and build a box that the inside space is less than 1 cubic foot.  Make sure you give barely  enough clearance for the speaker to fit.  If you have room, Go with a box and vent it with a 3 inch Vent tube 10 inches long.
