First pry off the rubber gasket. Then take a razor and cut out the cone, cut as close to the outer edge of the surround as you can. Then snip the tinsel leads connecting the cone to the spider. Then take your knife and cut out the spider. The cone and voice coil should now slide out. The rest of the speaker can be takin apart with a screwdriver and hammer.

Now hide from the owner of the speaker, he will probably want to hurt you.

I have a 12" d4 type r 1000 rms and a alpine 1000 amp speaker sounds great but smells like something is burning, my amp never over heats or shuts down but the smell is still coming from the sub?


Cut your gain back on the amp. It sounds like they are set too high. Check your install instructions on how to set your gain. If you have a 4 or 5 volt output head unit your will not be at half way. Im running a JL Audio 500 /1 on a skar wwv10 dvc in a ported box. My gain is set about half way & its plenty loud.I have a Alpine 9887 headunit 5 volt output on my RCAsI can take a volt meter & set my speaker output at 45amps & my gain in perfect.

What's the best Subwoofer box for a 12" alpine SWR-1223D?


According to the manual you should be looking at sealed, vented or bandpass type boxes. Really just depends on what type of bass you're looking to get out of it.
When you decide on the type check the manual for optimum specifications for the type of box you're looking to build.

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.

I just picked up a 12" type r in a box with a alpine m 350 how do I know what kind of type R I have without taking it out of the box?? and how do i hook it up to this amp??


Not to insult you in any way but u need to know how to wire into car's electrical system at the battery then to a fuse then to the amp and then output the signal from the deck to the amp.. finally to the subwoofer. you need to hook up 12V constant battery power , then remote from the deck ,ground wire from amp to chasis for power.. then wire to sub.

I have a set of Alpine Type R 12 inch subs... I have a 1500 watt amp powering them but when I turn the music up, the bass cuts out. Where should I start looking for the problem?


ground is loose(most likely amp), battery running low, subs might be damaged? feel free to keep me in touch if problem occurs more after checking grounds and power source and subs. Also might need to re-tune your head unit and amp?
