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

1 Answer

Has my subwoofer been blown?

I have single Alpine type R SWR-1242D subwoofer hooked up to an alpine MRP-M100.  I was driving one day and the subwoofer just stopped working.  I pushed on the sub and it did not feel blown out ( i blew a MTX sub a couple days earlier and could feel it when i pushed it in that the sub was dead.) .  I figured the fuse must be blown but could not find one.  Where would I look for the fuse, or does the speaker seem to be dead.

    i have a 15 inch alpine type r. i have tried all the wiring configurations possible with 2 different amps, and on either amp it will make alittle bit of sound but nothing close to deep bass, it will rattle when i turn the stereo up, making a sound like it is rattling right in the center. i have a 400.1 kicker amp and a sony xplod 1000x2. could i be that the speaker is not compatible with those amps. it is a dual 4 ohm voice coil. what might be the proper way to wire this speaker to one of those amps discribed above

How to wire 2 alpine typre r 1242 to an alpine pdx1000 mono amp??


If they are single voice coil, just hook one up to the amp (bridged) like normal and run a jumper wire from the positive of the sub to the positive of the second one, then do the same for the negative....This will give you a lower ohmage, thus better bass!!!

What is the best box for 2 ALPINE SWR-1242D 12"SUBWOOFERS TYPE-R NEW SUB WOOFERS


Ported and tuned to around 37-40 hertz. After all displacement the box should be in the 2.2 cubic foot for sub and you will be very impressed. Build it yourself for optimum sound and output.

SWR-1242D wired at 4ohms


Hi!

Having to much power for a subwoofer is a veeeery good thing, it will provide a lot of control and quality sound to your sub.

But this sub is a dual voice coil at 2 x 4ohm so if you want to hook it up at 4 ohm u need a 2 channel amplifier running mono mode.

i dont recomend that you hook up in 4 ohm, its better to take some time adjusting the levels on the amp and the headunit.

This system has the potential to create a realy good bass sound if u tune it the right way.
