This Alpine package includes a 500-watt mono amp, two 10" subs, and a sealed dual 10" enclosure that will all combine for some heavy low-frequency reinforcement in your vehicle. Just add some wiring, and you've got a complete system that will transform your music on the road.

MRP-M500 mono sub amp
Alpine's V-Power MRP-M500 mono amplifier drives your two subwoofer system with 500 watts RMS, with the sound quality that made Alpine famous. The thermal management system dissipates heat and saves power, so this amp will run reliably for years to come. The low-pass filter puts you in command of the frequencies that reach your subs, while the variable bass boost is armed with plenty of low-end punch. A subsonic filter prevents wasted energy by eliminating ultra-low bass, putting all the power where you need it.

Two SWE-1043 10" subwoofers
The 4-ohm SWE-1043 10" subwoofer handles up to 250 watts RMS, so this pair of subs makes a perfect match for the MRP-M500 amp. Alpine treats the two-layer pulp cone with Kevlar so it won't buckle or distort under heavy use, while the tough Santoprene rubber surround keeps your cone under control for more accurate bass. Extra venting maximizes air flow through your speaker, dissipating heat and increasing your sub's reliability. The heavy-gauge, stamped steel cage holds its shape through the most relentless pounding, so your bass stays tight.

Sound Ordnance dual 10" sealed enclosure
Sound Ordnance's rugged Bass Bunker BB102-75S sealed enclosure holds two 10" subwoofers and offers an internal volume of 0.75 cubic feet per chamber. This unloaded enclosure features high-grade, medium-density fiberboard construction, with sealed inner braces that help combat resonance by reducing vibrations.

Important Note: The amplifier in this bass package is a good match for the included sub(s), but it's still important to set the amp's gain controls properly to avoid distortion. This diagram shows you how to wire up the sub(s) in this package.

Amplifier Features

Power Supply: The MRP-M500 amplifier's power supply uses MOSFETs to convert DC battery voltage to the higher DC voltages needed for high power. It supplies positive and negative voltages around 0V, rather than around 6V as with conventional single-polarity power supplies. The result is higher power levels and a dynamic range wider by as much as 10dB.

Inputs: The amplifier offers both line-level and speaker-level inputs for 2 channels. The supplied speaker-level input harness allows you to connect this amplifier to a receiver without preamp outputs; aftermarket or factory. The speaker level inputs will accept the output from a high powered radio.

Terminal Covers: The amp comes with two plastic covers that protect and insulate the RCA, power, and speaker connections. Four supplied machine screws attach the covers to the amplifier.

Amplifier Controls

Low Pass Filter: The amp is equipped with a 50-200Hz variable low-pass filter with a slope of 24dB/octave. This being a mono subwoofer amp, the crossover is always engaged.

Subsonic Filter: This amp utilizes a subsonic filter at 15Hz to eliminate super low frequencies that can rob power and damage speakers. The subsonic filter operates at all times, and cannot be turned off.

Bass EQ: The Bass EQ circuit provides a variable boost (0-12dB) at 50 Hz.

Amplifier Connections

Left Side Of Amplifier:

  • GND (ground): gold-plated screw terminal, 0.33" wide
  • Battery: gold-plated screw terminal, 0.33" wide
  • Remote: gold-plated screw terminal, 0.33" wide
  • Speaker Output: gold-plated screw terminal, 0.33" wide

Note: Alpine recommends 8 gauge power and ground wire (minimum).

Right Side Of Amplifier:

  • Line Inputs: 1 pair of gold-plated stereo RCA jacks
  • Speaker Level Input: Molex plug input for supplied 4-pin harness

Subwoofer

Woven Fiber/Kevlar Reinforced Pulp Cone: This Alpine Type-E subwoofer features a two-piece parabolic woven fiber and Kevlar reinforced pulp cone. Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design. The lightweight cotton fiber design provides a faster and more dynamic response from the woofer.

Santoprene Rubber Surround: The high-excursion, tapered half-roll, injection molded Santoprene rubber surround is durable and resistant to the elements, resulting in a very reliable performance. The surround is specially designed to resist deformation that is common in woofers with wide surrounds. This design gives the surround more control over the woofer cone to reduce distortion and possible driver failure.

Progressive Nomex Spiders: This subwoofer utilizes a Progressive Nomex spider for stability and mechanical durability. The custom progressive roll gives the woofer a longer, more linear stroke with maximum centering and restoring force. Special edge control design and Nomex construction provide excellent tear resistance, strength and long-term reliability.

Voice Coil: The Alpine SWE-1043 features a 4-layer single voice coil made from 180-degree high-temperature wire on an aluminum bobbin.

Airflow Optimized Extended/Vented Pole: This SWE-1043 features an extended pole piece which provides optimum airflow for the woofer.

Custom High Strength Steel Basket: The frame is custom stamped from high strength steel.

Speaker Terminals: This Alpine Type-E subwoofer features a pair of heavy duty push-terminals on one side of the woofer's basket that will accommodate up to 8-gauge speaker wire.

Tinsel Leads: The Type-E subwoofer uses insulated 16-gauge stranded tinsel leads.

Gasket Cover: Alpine uses a Concealed Mount Gasket System to cover the mounting screws for a clean look. The black rubber gasket ring comes already installed on the woofer and needs to be removed before drilling the mounting screws (not supplied). The gasket ring then snaps back into place once the woofer is mounted.

Protective Grille: The Alpine SWE-1043 Type-E subwoofer comes supplied with a high impact protective grille. The black plastic grille snaps onto the woofer without the need for any additional hardware. The rubber gasket cover must be removed when using the grille. The grill also hides the mounting screws, as well as protects the woofer. The grille adds 0.9725" to the woofer's height (1.6875").

Enclosure

Materials: The Sound Ordnance BB102-75S Bass Bunker is an unloaded, hatchback-style sealed enclosure for dual 10" subwoofers. It is constructed of 5/8" MDF (medium-density fiberboard), covered in black carpet.

Internal Box Volume: The enclosure has two separate chambers, each with 0.75 cubic feet of airspace.

Terminals: The BB102-75S is equipped with two pairs of spring-post speaker terminals, one for each chamber, mounted in the rear panel. The spring terminals will accept bare wire, pin connectors, and single banana plugs, but are spaced too far apart for dual banana plugs. Inside the enclosure, each set of terminals has an attached 18" length of speaker wire for connecting the subwoofer.

Brackets: Brackets for securing the enclosure to your vehicle are recommended.

woah!! - but vibrations?

Written By Paul, Ann Arbor, MI on Wednesday, January 04, 2012

As far as bang for your buck goes - this is your bass package. big crutchfield fan and I'm happy with my purchase as always. These subs hit harddd!! I drive an 05 Mazda 3s (abnormally large trunk space) with 140k miles and my subs fit in there with no problems at all. I LOVE THE SUBS......BUT my only problem with them is now that I've owned them for about 7 months they're really starting to vibrate.

Let me clarify... When I say "they" I mean "something" in the trunk/back of the car. I can't tell if the subs are just rattling my back window or if the plastic covers that snap onto each woofer are going nuts.. Either way, I'm having a lot of issues with vibration (to the point of cringing and changing the song) whenever I take the volume past roughly 1/3 of it's potential.

and for the record, these vibrations didn't exist in the first few months - making me wonder if the subs are just rattling my car to pieces....

to clarify once more! I LOVE THE SUBS and the fantastic depth of sound they add, but the vibrations are really starting to bug me :(

and on one last side note - they took roughly 2-3 weeks to "break in". Generally, the bass just became sharper, clearer, and more distinct after 2-3 weeks.

Pros: PRICE - CRUTCHFIELD SERVICE - PRICE - CRUTCHFIELD COMBO PACKAGE SIMPLICITY - CRUTCHFIELD EASY-INSTALLATION GUIDE - BOo0Oo0Oo0Oo0Oo0O0oO0oO0oM! Hooray Crutchfield! :D

Cons: VIBRATIONS - might just be my car, but I can't tell for sure where all the vibrations are coming from!! I can hear vibrations from the head unit area and the rear view mirror all the way back to the trunk area.. (rear window?) - I tried facing the subs forwards and backwards but really didn't notice much of a difference in terms of vibrations KEEP IN MIND - these could all be due to my particular car. Other people might have better experiences in other cars..

Sweet package

Crutchfield Customer Review (What's this?)

Since I am not a filthy rich guy I need to cut costs. I do not like poor quality though. I was sceptical about the whole package deal thing, especialy for what I paid for this. What I received was exactly what I hoped for...Great quality sound for not alot of money. The S/O bass box is also good quality. Since places like Best buy sell the same thing I was afraid it would not sound good. Strong and clean bass and goes well with my Boston Accoustics in the doors.

Lots of boom for the buck

Written By MorganH, Center, CO on Sunday, January 30, 2011

I've had these subs for almost six months and the results are incredible! They pick up
the real low notes nicely and the high bass isn't bad either. They're great for hip/hop, rap,
and pop, but they make country, rock, and metal sound emmaculate as well. The sealed
box provides clean bass, but these subs will over power your system if they aren't tuned
right or if you have weak factory speakers. The amp makes tuning the bass a breeze,
just turn the knob- simple. I installed this kit myself in the trunk of a four-door sedan and
the bass can be heard from about 1000ft away. If you want to impress your friends with
high quality subs without breaking the bank, this is the way to go.

wow
