OVERVIEW

by Crutchfield's

Get noticed

Alpine's BassLine subwoofers will add some serious rumble to your vehicle's sound system. You'll really feel the impact of bass lines and drum beats, so you can get into your music like you never have before. These subs also live up to Alpine's reputation for making subs that bass lovers want, but they don't cost so much that you end up actually living in your car.

The tough steel frame helps to keep your bass punchy and accurate.

Built Alpine tough

Alpine's BassLine SWA-10S4 10” sub comes equipped with a rigid polypropylene/mica cone that won't flex under high volumes and cause distortion, while its poly-foam surround will last for years to come. The tough steel frame offers the stability you need to keep the bottom tight during intense bass sessions. This sub handles up to 250 watts RMS and its 4-ohm impedance makes it a great match for most amplifiers.

Need an amp for this sub? Check out this Crutchfield-approved bass package.

To drive this single subwoofer, we recommend a mono amplifier rated between 200 and 375 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Good name, RMS was in the right area for my application. I listen to a lot of blackened death metal, where 12s would be too much, I needed 2 matching subs in the ballpark of 200-300 RMS.

Would a 1100 watt boss amp work on 2 alpine bass line 10 inch woofers?

[ staylo Mar 19, 2017 ]

1 answer

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

[ Kenny Mar 15, 2017 ] Staff

i am currently running two older style audiopipe 10" subwoofers along with a 1000watt audiopipe amp and i was looking for something with wayyyy deeper bass. as of right now, i have them set up in a ported box in the back of my 06 Tahoe. I am looking to replace these to get something that hits wayyy harder. i was deciding on either the Rockford R2D4 or the Alpine SWA-10S4. Any suggestions?

[ Alek Nov 30, 2016 ]

1 answer

I am running the RF R2D4-10 with a simple old punch 45 I have them in a ported box I was told my amp was not big enough but I have awesome bass with these speakers I can not eve image what you will have with a 1000 watt amp

[ ROBERT L Dec 01, 2016 ]

If you had to pick one which would you pick? 10in Alpine BassLine or 10in Kicker Comp?

[ Tom Oct 23, 2016 ]

Not shur! I have the alpine! Never had kicker. But I can say is that the alpine are a great starter woofer! Robert t

[ Robert Turner Oct 24, 2016 ]

I'd choose the Alpine. It is really well-built. Amazing for the price.

[ Jeffrey Oct 24, 2016 ]

I had a mtx jackhammer at 200rms Max rating. It blew when listening to loud bass the other day after having this for a few yrs. Will the alpine handle my jvc-ksax4302?

[ James Aug 16, 2015 ]

5 answers

It most certainly will. I have 2 alpine bass line subs in my 06 GMC Sierra with an alpine 500 watt sub amp. The feel & the clear bass from those subs are well worth the money. I highly recommend them if you're looking for some good clean solid bass. I wish I had got the 12's now but those 10's pack one heck of a punch!!????????

[ DON Aug 21, 2015 ]

Yes, they are very durable and very accurate.

[ RICKY Aug 18, 2015 ]

no !

[ MARVIN R Aug 18, 2015 ]

AFTER A FEW MONTHS MY ALPINE BLEW WITH A ALPINE MRV 500 AMP SO TO ANSWER YOUR QUESTION NO

[ keith Aug 17, 2015 ]

Yes it should handle it with ease. I have approx. 700 watts going to one of mine with no problem at all

[ JUSTIN Aug 17, 2015 ]

Are these better in a sealed or ported box? Looking to put them in the truck of a 08 aveo. And what size amp would be good for the install. Thanks.

[ Robert Turner Oct 24, 2016 ]

I am using a sealed box. I only have one 10" and I'm using a 200 watt MTX amp. I have it installed in my GMC Denali. Nice clean sounds and not over bearing.

[ PERRY Jan 17, 2015 ]

250 watt rms per sub. Go by that. I put a 250 watt amp to 2 of these n it works pretty good be better with a 500 watt n I have a sealed box.

[ JOSHUA S Jan 15, 2015 ]

Sealed is definitely the appropriate enclosure for this sub. I run 2 in a custom built box in an F150 Supercrew using an Alpine MRV 500 bridged to 2 ohm and it produces plenty of bass for the cabin of my truck.

[ RYAN M Jan 15, 2015 ]

My daughter has them in a sealed medium size generic box in the trunk of a newer Ford Focus. Powered by alpine mrp 500 mono amp. They beat pretty good

[ LANE Jan 15, 2015 ]

You can go either sealed or ported, but make sure you follow the specs for both. I'm personally running 2 of these 10 inch in a sealed box under the back seat of my 07 Silverado LT and they sound great. I was quite impressed with them. I'm powering them with an Alpine MRP-M500 and it seems to do just fine.

[ ron Jun 12, 2014 ]

Ron they will fit you 06 if you get the correct custom box for your truck. I have an 06 Sierra with a down firing sub box with two 10"alpine Bass Line subs that really thump (non ported). But yeah the correct box for your model truck & you're in there my friend...

[ DON Aug 21, 2015 ]

Ron I have a 2011 crew cab they wouldn't fit. I had to return them.

[ RICKY Jun 12, 2014 ]

Will this replace my factory ford expedition 2003 sub?

[ ivan Mar 27, 2014 ]

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.

[ Krissy Mar 28, 2014 ] Staff

[ kevinn Feb 24, 2014 ]

These are priced per speaker (one subwoofer).
