there are the best get the memphins

The speakers should be fine but i wouldn't push that much power to them thay are now in a weaked state

Kicker speakers always require very large boxes (you're looking at 12 cubic feet for both), when ported. Ported boxes are very sensitive to box size, port tuning etc, so it's probably best to leave it sealed, as they are far more leniant, and sealed boxes are usually 1/2 size of ported boxes. You would get less bass when ported than with sealed (because ported boxes must be bigger to match the sealed ones).

If you wish to experiment with the bass response of speakers, download winISD, and put your speakers in, see what size boxes give you what.

did you build the box yourself? because ones from the store have ports in the back of the box. all you do is run a wire from the sub to the ports in the back of the box, which on the outside is connected to the amp.

Hello bgl6176,

According to their specs, the L7's will work in a ported enclosure with as little as 3 CuFt and up to 6 CuFt. Usually with ported, bigger is better, so let's use the 5 CuFt per chamber. I'm assuming that you have room for a 10 CuFt box in the trunk? That's a big box? Almost half as big as a medium sized refrigerator. I hope you don't plan on putting your golf bags in there too. For 10.15 CuFt, a box will need to be 36X29X20, allowing 0.15 for the partition, sub, and port displacement.

To tune each chamber to 30Hz, you need a 4" diameter port 4.6" in length. Lots of custom builders use PVC and even ABS pipe for round ports. You can also buy "pretuned" ports from sites like www.partsexpress.com.

You'll have to measure the exact room that you have available and then adjust the dimensions accordingly.

Here's a link to a great site for calculating almost anything in box building and subwoofer related. You can use the old "multiply LxWxD and divide by 1728" and the other formulas too, but here you can plug the figures in and immediately see the results.

Hope this helps.

you should use an amp with approx half the power of the speakers max output (i.e 1000 watt speaker use no more than 600 watt amp)

The cutout simensions for the kicker 15" solo baric are 13.75".

there is no such speaker as a solo-X L5.
The Solobaric L5 is 450Watts RMS and 900 Peak.
Check your documentation, and no warranty except Massive Audio covers Burned Voicecoils as it is deemed customer abuse.
If it is a typo, and not an L5, your combination (as long as each is level matched) should be ok to run on that sub. When wiring it as you describe, the two amplifiers need to be identically matched in order for both coils to play at the same level.
Seek professional installations so your warranty is intact.
