I didn't like the signal-to-noise on the MB Quart amp.

That cheap SPL had better specs, but who knows if you can trust those numbers.
"Numbers" get played with all the time.

That DIYMA site looks like a bunch of hackbobs pawning their junk.

Deal with a reputable business. Not some joe-schmoe on the internet.

Help/advice Matching amp to subwoofer...

I'm having trouble understanding about Ohms, # of voice coils, etc. Matching Amp to sub-woofer seems to be very important...

So what if I get a Pioneer Digital Series Class D Monoblock amp! what would be a good SQ 12" or 15" subwoofer to match this amp? Or is this a good amp to hook up 1 of my old Solo-Barics? ["single voice-coil sub", 8ohm]

LINK to amp specs



GM Series Class D Monoblock Car Amplifier
RMS Power Rating:
4 ohms: 300 watts x 1 chan.
2 ohms: 600 watts x 1 chan.
Max power output: 1200 watts x 1 chan.
MOSFET power supply
Wired remote bass level control included
Variable bass boost (0-12 dB at 50 Hz)
Balanced isolator input circuit
Speaker-level inputs with included high-level to RCA adapter
Heavy duty aluminum alloy heatsink
Chrome-plated RCA level inputs
Chrome-plated screw terminals
Variable low-pass filter (40-240 Hz, 12 dB/octave)
CEA-2006 compliant amplifier
Frequency response: 10-240 Hz
Dimensions: 11-3/8"L x 7-7/8"W x 2-1/4"H

I appreciate every single input... thanks

That amp needs to be at 2ohm for 600 watts so the ideal solution would be a sub with either a single 2 ohm voice coil or dual 4 ohm voice coils. Either way would give you 2 ohms. You could also run it at 4 ohm but you will only get 1/2 the power you get at 2 ohms. If you wanted to use your Kicker subs you can hook 2 of them up and get 300 watts (150 each) or hook all 3 up and get roughly 500 watts (166 watts each roughly).

In other words, this would be the perfect woofer ...

Power Handling:
Peak: 1800 watts
RMS: 600 watts

I've got the 10" version of that puppy (thanks to Alien Mantis's suggestion on my build thread) and I'm VERY happy with it!

[Palmer812]

That would be a great choice. Do you have any local shops that sell Alpine? I would match that price all day long and if you blew it up you could exchange it over the counter.

Thanks Herb, yes I do remember your set up, I was hoping to get a feed back from you too!

Responding to AM's thoughts on the different enclosures...

He's absolutely right. You can absolutely get good sound out of both. I should PROBABLY be using a vented enclosure on my sub with the amount of power I have. Instead I'm keeping it sealed. Hell, I'm even looking at an 18" woofer. Maybe around Christmas I might do another enclosure...

[Alien Mantis]

I knew an audiophile guy who was a recording engineer.

He always said, "there is life below 40hz"

( maybe for HIM )

Oh hell, I cross my mid bass at 40 Hz...I can definitely say that there is life below 40Hz

Me too! but at 63 Hz... I know your L8s must sound amazing I only have cheap 6.5 drivers even though the midbass is great (I never realized about it, but I've been missing this frequency in my old installs that all songs sound so different now)

and WOW! I've been learning so much about mid bass that I understand now when you say that it's so important for a good sound system.

with some songs I mute the subwoofer and I can't tell the difference, then I mute the midbass and turn on the sub again and sounds like crap! the mid bass does all the job!

last but most important... Sqcomp! I'm going to give up! you are absolutely right, go with kick panels on the floor for midbass drivers, my doors are driving me crazy, I tend to rest my left arm and knee on the door panel and buzzes so much (no rattles, just vibrations) so I'm going to make some small kickpanels.

I got some used 6.5 drivers (not high end, I can't remember the brand and specs) but hopefully one day I'm going to be able to afford HAT L6's ( I think they go for $500-$600) for now I'm going to experiment with these little 6.5 woofers in kickpanels.

Man! this is like "THE NEVER ENDING STORRY" just like you thinking about an 18 in sub for Christmas.!

Thanks again guys! all your input helps me gain knowledge and correct my mistakes I hope helps others to understand how everything works.

[Alien Mantis]

Yeah, this is turning into a soap opera.

Or worse.... a reality TV show without the TV!

[derickveliz2]

Thanks everybody, lets see what happens at the shop, they call me and I'm going to stop by this week.

[sqcomp]

Absolutely experiment. I did a bit of planning when it came to door panels versus kicks. What you trade is space versus performance. I'd rather have performance.

I've taken apart the door panels multiple times. With some work you can quiet them down.

You're tending to lean on the silver door control panel/insert piece or the top of the door sill aren't you?
