Alpine BassLine Series 10" subwoofer

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.

Theyre good subs but, not great. For the money theyre worth it though.

Features

PWR Cone Design: This BassLine subwoofer's patent-pending Progressive Wavelet Ribs (PWR) cone design helps break up standing waves and cone resonances to keep distortion low. The sub uses a polypropylene and mica damped cone assembly and a high-excursion poly-foam surround.

Progressive Polyester Spider: The progressive polyester spider provides accurate control of the subwoofer cone motion.

Two-Piece Yoke: The two-piece yoke uses a vented pole to provide improved air flow and help cool the voice coil.

Spring Terminals: The spring post terminals accept pin connectors, single or dual banana plugs, or bare wire up to 8 gauge.

Enclosure Compatibility

Sealed Box Volume: The recommended sealed box volume range is from 0.65 cubic feet to 1.0 cubic feet, with 0.83 cubic feet being the ideal size.

Product reviews from the Crutchfield Labs

Alpine's BassLine subwoofers will add some serious rumble to your vehicle's sound system, but they won't break your budget.

A lot of loud, not a lot of green.

Written by Chris, Advisor, on 11/7/2013 2:26:00 PM

I walked by this subwoofer the other day in our lab and decided I'd try it out in my Jeep. It's enclosed in the Sound Ordnance BB10-1V vented box. Currently, the sub I own and listen to in my Jeep is another Alpine. For space concerns, I bought the SBR-S83V which is also a vented enclosure, but has a Type-R 8" woofer.

This Bass Line woofer is considerably louder even though being a single four ohm voice coil woofer, it draws only roughly half the power from my JL Audio amp.

The bottom line, after a week of listening, is this woofer costs very little, requires little power to get it moving, and in a medium sized vented enclosure is very loud!

I like that my smaller 8" sub and box takes up a lot less space so I'll be putting it back in. If your space isn't so limited, like the Jeep, then you'll love this woofer.

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. Bought these to replace a mismatched pair of Clarion 200 RMS and MTX 300 RMS 4 ohm subs. [ Lucinda  Mar 21, 2017 ]

Reviews were great on this item, and the price is also. Can't wait to install it in my son's truck and eliminate the old sub he's using now. Also, the customer service on "live chat" was awesome. [ Steve  Feb 03, 2017 ]

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 ]
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 ]
And I have a 96 3 door s10 with 2 alpine 10s . With Orion mono ported box . Tight sound. Good buy.Robert t [ 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. [ JOE  Jan 15, 2015 ]

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 ]
