Hey guys... here is my dilema. I currently have a Kicker Solo-baric L5 10'' DVC sub & kicker's ported box (long & narrow) powered with a Alpine digital MRD-500 amp. Sub is rated @ 450RMS, & amp is 500RMS. I have a 4 gauge kit from knukonepts, 300 watt alpine amp for my speakers. Input is a Jensen in-dash DVD H/U. I have a Exide Gel battery & a 140watt alternator.

I'm not happy with the bass at all. First off, the sub's rubber outside rattles at full volume and sounds awful... fixed if I press my fingers against it. I don't think its the mounting but the rubber flexing, would a bad voice coil do that?

I'm thinking about making a sealed sub box and maybe getting a new Kicker sub/warranty. I don't work aka computer geek so plenty of time.

I had a JL 12inch in my Eclipse GS-T before I sold it. Loved it. That got stolen and had a Infinity 12inch, loud but didn't hit has hard. Like it. Going from a hatchback to a trunk I feel my current setup isn't what I thought it would be. I don't want crazy bass, just a single sub, good punch, pretty deep sounding.

Given what I have said. Which route should I go?

1.) Replace the Kicker L5 10'' and build a sealed box.
2.) Replace it with a L7 10'' in a sealed box.
3.) Replace it with a L5 12'' in a sealed box.

I don't I think a L7 12'' sub because I then would need a new amp.

Advice, comments.... suggestions? I did stick a sweatshirt in the ported hole on the box and it did sound better.

jl w6v2 ported or sealed... You won't regret it . What are teh specs on the amp though 1 ohm @ 500 rms ?

 

The W6 is a great choice.

 

The alpine is rated @ 2 ohm. I don't have the specs sheet to see what it is at 14.4volts.

What size of W6.... 10'' or 12''? Best for my amp. I only want one, i like my trunk space.

 

Well, if your amp is rated at 500watts rms, you can purchase either the 10 or the 12" sub and be happy. If anything, it would come down to how much you wanna spend.

 

I think I'm going to try a JL 12'' w6v2.

Here is what I have in mind for a box: (inches) Width X Height X Depth
W:28 H:14 D:9 Thickness:.75 (3/4) = Interior Volume:1.43 cubic feet.

Sub mounting depth: 7.6''

They recommand:
W:18 H:14 D:12.75 Thickness: .75 = 1.25 cubic feet
but when I input that into the volume calculator I get 1.34 cubic feet

Whose numbers should I go by? I would like to go wide and narrow if I can. Any effects on sound, punch, deepness etc?

I have 2 12" JL W6V2's and a 100/1 JL amp... it rules all..to me.. except a dub7 of course

 

The number that JL is giving is the box volume after taking into account the sub's displacement.
