Sub and Amp Choices

847 Views 2 Replies 3 Participants Last post by  Circuit
So I have decided to begin an attempt to compile a decent sub and amp setup in my car. I am aiming for two 10" subs and a mono amp.

For the Amp: Alpine MRP-M650 Mono
# 400 watts RMS x 1 at 4 ohms (600 watts RMS x 1 at 2 ohms)
# Variable low-pass filter (50-200 Hz, 24 dB/octave)
# Tuned Bass EQ (0-12 dB bass boost at 50 Hz)
# Subsonic filter (24 dB at 15 Hz)
# MOSFET power supply
# STAR Topology (minimizes internal noise and prevents ground interference)
# Speaker- and preamp-level inputs
# Gold-plated screw terminals
# Fuse rating: 30A x 2

Now for the Subs: 2 Alpine Type S SWS-1023D 10's
# 10" subwoofer with dual 2-ohm voice coils
# pulp/glass fiber cone reinforced with Kevlar
# Santoprene rubber surround
# power range: 50-300 watts RMS (150 watts per voice coil)
# peak power handling: 900 watts
# frequency response: 31-700 Hz
# sensitivity: 84 dB

:scratch: Now heres the deal, I am a relative noob when it comes to audio.

Are these subs of good quality? any opinions would be great!
Is this amp powerful enough to handle these subs?
I know Alpine features great quality, but overall, does this system seem like a good setup

heres my :twocent:

I highly recommend alpine, I installed a Alpine Type R (10in) and a MRP-M500 in my car and it provides great bass fill for the music i listen to.

A couple things to consider.
2 10in subs in a properly sized box (vented or sealed) is going to take up a large amount of space, not all but a lot of your trunk, even my one 10in really cuts into my available truck space.
MRP-M650 amps are NOT made anymore, your options are MRP-M500 or MRP-M850 or a PDX series (TONS more expensive but 600w available). You may be able to still get one off ebay, but its luck of the draw.

I HIGHLY recommend a either 10 or 12in Type R sub, these are slightly more durable subs, and allow you to run at a higher RMS wattage i know with my 10in I run almost 500w RMS in with no problems running at 2ohm. This would allow you to have just 1 sub and save a lot of space, plus I LOVE the sound of my sub, its accurate and deep it can provide just fill or really bump the car.

Also depends on what kind of music you listen to. I love alt rock and some country and just wanted to fill out the lower end. I have a sealed box which provides more accurate and punchy bass although it is slighly less overall volume. If you go with a ported box MAKE SURE YOU HAVE A CUSTOM TUNED BOX BUILT. If you use a prefab ported box no matter what you do the bass will be inacurate and sound shittier than it should. BuckyBoy on these forums custom makes these ported boxes and they are great from what I have heard.

Also do not forget about the overhead costs in wiring (power and audio) as well as either a line converter if you are using the stock HU or consider purchasing an aftermarket headunit (i personally love my ida-x100 no cd but amazing interface) aftermarket headunits will even make the stock speakers sound a bit better

So in summary.
1 A higher end sub can save you the space that two would take up look at Type R instead (2 voice coils at 250w RMS each)
2 Proper enclosure makes or breaks the sound, ensure it meets the subs factory specs (I use a .65cu ft sealed box which is tiny but recommended for the sub)
3 If you are on a budget make sure you have enough to get the job done, from fuses to wiring to the actual components (I was gonna do a 4 channel amp as well but ran out, but all my wiring will support my future purchases!)

I'm sure Circuit will chime in here too on what he thinks, but take a look at Hijackers install he uses a lot of Alpine stuff and his looks really spiffy too! Just look around the forums to see what other combinations people have used, stick to name brands though Alpine, JL, Kicker, etc are quality products

end rant.

BMoreRacer, that is a perfectly matched setup.

+erep to on the box for a good suggestion and good advice on the enclosure, but I think what he has will work well.

The main reason I would go with the dual type-S's instead of a single type-R is output. They will have double the cone area and therefore will have a lot more output, for about the same price.
