BassPro SL is rated 4.7 out of 5 by 30.
Rated 5 out of 5 by from Exactly what I was hoping for I've only had this sub installed for a few days now, but so far I'm loving it. No, it won't blow your windows out, but it is more than capable of being heard over the wind noise of a soft top Jeep Wrangler on the freeway. It was super easy to set up with a bit of wire and the included instructions.

Purchased the BassPro SL for my 2004 Jeep Wrangler. Sound great!! better then expected..  Cant figure out how to have the sub turn off when I turn the car off.  I hooked up remote wire behind the radio. amp/sub always on?? help? 

Asked by: JeepMike
There are several reasons why this might happen. It could be a grounding issue, speakers using a common ground, or the placement of wires. Please submit a case at www.jbl.com/support-contact.html and our Customer Service team will be glad to assist you.

Do you know if this will fit 2005-2009 Subaru Legacy GT? I've searched all over the internet for the Subaru under-seat sub dimensions to compare. I do not have the optional NAV system. Thanks

Asked by: UnkBo
The BASSPRO SL's Dimensions are (L x W x H): 13-9/16" x 9-7/8" x 2-13/16"(344mm x 250mm x 71mm). Please measure the under-seat dimensions of your vehicle to see if it can accommodate the speaker specs.

Do you need an amp for this sub?

Asked by: nectarbass808
The BASSPRO SL is a powered sub. It doesn’t need an amp. It can connect to a head unit as long as the head unit has a sub output.

Can you connect two together?

Asked by: Neogeo
It is not more of connecting them together but using two in one set-up – which is definitely possible, provided that your car battery/batteries can provide enough power for two of them. Since the BASSPRO SL is a self-powered subwoofer, you do not necessarily need to wire them together but simply run separate wires for them. For power and ground, generally, you have two options, to wire them individually or wire them with a distribution block. For the remote cable, you may find that a single remote turn-on lead is unable to handle the current draw demanded by multiple amps. One way to work around this issue is to connect the turn-on leads from your amps to a relay, which is triggered by your head unit. Now for the inputs, this depends on what your head unit offers, if it does have low-level (RCA) or high-level inputs (speaker wires). The BASSPRO SL can accommodate either form of connection and would require you to split the outputs from your head-unit to wire both amplifiers. It is important to remember to set the gain and crossovers at the same level.

Will this work with the factory radio in a 2016 Ford F150? 

Asked by: Gonz11
Yes, the BASSPRO SL will fit in any car because it could be mounted wherever you choose, under a seat, in the trunk, etc. As for connection, it will work in virtually any car because it can be connected via speaker or line level connections, so it can be connected directly to the head unit, or it can be tapped into the speaker lines. Wiring will be needed, and it must be connected directly to the battery, and should be installed by a professional.
