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

SWR-1242D wired at 4ohms

Hey I have a single SWR-1242D with a MRP-M1000. The only wiring diagrams it gives me are for 2ohms and 8ohms. The amp at 2ohms would be giving 1000rms which is more then the like 600rms the sub can handle so im worried about blowing it. Also to my knowledge(which there is very little of) I cant or should not wire it for 8ohms. If anyone can please help me out I would greatly appreciate it.

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.

What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...


I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

I have two type-rs hooked up to a mrp-m1000 and its not hitting hard at all! but when one is hooked up it hits harder than two... so is it the way its hooked up or do i need another mrp-m1000 amp? or can i...


If the speakers are rated at 500W or greater, then you'll need two amps to get their full potential. When you connect two to a single 500W amp, each speaker only gets a max of 250W. Also, check the ohm rating for the outputs of the amp and the ohm rating of the speakers as well. Unmatches speaker/amp impendence also results in poor performance. If you connect two speakers to one terminal, the total impedence of the speakers falls by 1/2 (two 4 ohm speakers wire together will result in 2 ohm impedence). So, if you have an amp rated at 4 ohms, you could connect two 8 ohm speakers to a single output. Hope this helps some!

NOT SURE WHAT OHMS SUB I NEED!


if you get the 4ohm you can wire it to run a 2ohm an the kenwood amp will push 900 watts at 2ohms.they say it can push up to 1800 watts,that would be at 1ohm.that kenwood runs 500 at 4ohms an 900 at 2ohm.if you need help wiring the sub or anything else let me know bertman285@hotmail,com Max Power Output 1800W Power Output 4 Ohm [14.4V] 500W x 1 [20-200Hz, 0.5%THD] 2 Ohm [14.4V] 900W x 1 [100Hz, 1.1%THD] Bridged[4 Ohm] -

How do i install mrp m1000 to two type r 12s step by step.


Hello chadbcavanau,

See the link here for a step-by-step install with photos and amp wiring diagram.

First you need to purchase an amp wiring kit (minimum 4 gauge power and ground). If your vehicle is equipped with the stock radio, you'll also need to purchase a line output converter (LOC).

Hope this helps.

How do you wire 4 kicker cvr dual voice coil 4ohms to a 1500.1 kicker mono block 1 channel amp, they sound distorted when i turn them up, how should i wire them?


Hello antjobe,

According to Kicker the 1500.1 is only stable to 2ohms. So you will want your 4 CVR's to present a 2ohm or higher impedance to the amp.

The best configuration would be to wire the voice coils in series (each sub 8ohms) and then parallel all of the subs to the amp (2ohms). Here's a link to the diagram.

Hope this helps.

Amplifier wont move subs


I dont know if this will help you but start at the deck and make sure that the outputs(RCA) arent crossed over to highpass and do the same at the amp make sure that its set for lowpass- set half gain -bass boost half gain- subsonic minimum - If that doesnt help try using an i pod with an adaptor that you can play it right into the amp this is to see if you are getting signal from the deck to the amp if it doesnt work with an i pod or mp3 plugged directly into it then you may have got you a blown amp going on- good luck with that

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.

4000.1 soundstorm amp


Hello GregV24CHOPP,

The Soundstorm products are in about the same category as Boss, Visonik, Pyle, and Lanzar to name a few. Somewhere between overrated and definitely overpriced for the quality you get.

Look into the Alpine MRP-M1000. RMS = 1kW into 2ohms (600 into 4ohms), YES 4 OHMS(!), real power. No, it WON'T do one ohm. But most of those claiming to are not CEA2006 compliant anyway and can claim any power at any load and advertise for whatever buyers they can attract for their bottom-of-the-barrel products.

The MRP-M1000 is currently on sale at Crutchfield for only $347. Awesome power, and very good sound quality, too. I'm currently running 2 4ohm MTX Thunders off of "little brother", the MRP-M500, and they really shake the pavement.

You have to spend good money to get good power, there is no way around that.

The only wiring configurations for 2 2ohm DVC subs result in 0.5ohm, 2ohms, and 8ohms impedance. Check the Rockford-Fosgate "wiring wizard" for the different diagrams.

Hope this helps.

How to wire 2 ohm 2 12ich alpine type r's to box terminals?


Dual 4 ohm subwoofers can only be wired @ 1 ohm, 4 ohm or 8 ohm.
2 ohm mono load is not possible.
You will need to use (1) subwoofer to get the 1000W out of the amp.
Wire both positives on one sub to + on amplifier and both - on the same sub to - on amplifier to give the amplifier a 2 Ohm load.
Add a second amplifier, or buy an amplifier that is 1 ohm mono stable.
You can wire both to the amplifier at 4 ohms 600W, but they will share the power and only see 300W ea.

Unsureness of wiring configurations.


Mamola,

Get an amp with at least 200 Watts RMS. The RMS value is what is important about driving Subs. This could be proclaimed to be a 1000 Watt amp. REad the RMS value.

Wiring. It is better to series your Speakers to give them and your amp more reliability,

Get a Mono or Bridgeable amp. If it si bridgeable, BRidge the output as described in the manual you get. Some Amps have a diagram right on the output..

AMP+ to Sub1 +
Sub1 - to Sub2 +
Sub2 - to Amp -

Get a 4 Guage wring kit. Run your power wiring down the Drivers side, and Audio signal wiring down the Passenger side, keep the two separate.
