had 2-154's in trunk of 79 delta 88,4.5 cuft per sub with a punch 800.2 amp at 1/2 volum the trunk would flex 2 inches u could look nside the trunk!!! super rediculus bass! only ran amp n stero at 200 watts rms @ 4ohms. i could only imagin what it would have sounded like a 1000 watts rms.

needs huge box for the deep notes.

if u want loud i recomend this sub.can't beat 4 the money....sold them with car can any 1 tell where i can get these woofers now?

Great performance in a small, heavily stuffed sealed box. I listen to music with lots of electric bass (rock, jazz, acoustic) and with the 154 it's like being live at a venue, the bass compresses your chest and goes through you, it's merciless. Once I got surprised by a really powerful transient in an unfamiliar song while going down the highway and actually ducked. Good resolution too, distinct bass notes as opposed to just noise.

For the money, are you kidding?

Getting hard to find anymore.

Ridiculous sub for the money. I modeled it in a 1.4 cube sealed box and didn't believe the amazing results until I got it in the car.

With a Linear Power 2202 bridged mono and a 1 Farad cap, it gets loud enough on bass tracks to cause me pain firing backwards in the trunk of an '05 Hyundai Elantra. I haven't measured it yet, but I'd bet at least 135db.

Impressive output for only about 350 watts RMS from the 2202 in a highly inefficient enclosure. Can't imagine what it would do vented with, say, a Linear Power 5002 at close to 1000x1.

I originally bought this sub to run aperiodic (lots of xmax, efficient, huge cone), but am too busy to build and tune that type of box right now. Went sealed temporarily after modeling things on the PC, and it's pretty amazing.

PPI C2 10" subs in a Deathbox (bandpass)
CV XL-12 subs many years ago

96SPL rating, good excursion, high power, and sound quality.

not very tight response, but still alright.needs alot of air space.

when i purchased this i had it in a 1cf box with a 200 watt kenwood amp an it sounded great in my civic hatchback, then i had a costom built to specs box(its a monster 4.0 cu. ft. slotted box) but my amp killed over and i was running it off my 40 watts preamp on my deck, and that also sounded good with its spl rating at 96DB 1ft. 1watt. then i baught a 400 watts RMS profile amp andim hitting 141DB with one 15"!! im very happy with my Cerwin!!!

jl 15w6, fusion 15", rockford Z 15"none of these compare besides the JL i would give them equal props.

Loud clear bass, great frequency responce on all notes.

requires being in a ported box, doesn''t carry sound far no BOOMING 3 miles away. THe bass won''t travel through anything, as in: my back seat(i have a honda accord), windows (when up), buildings, walls, large animals. every little imperfection in any audio recording is noticable

I bought this sub after many months planning to get the perfect bass in my car. This sub is pretty loud but as far as thumping i would have to say that it just doesn''t happen. I don''t think it''s the subs fault it''s just that ported boxes(that are required) look better in statistics than they sound. I followed the box specs to the T and have a very nice setup with a fostgate amp 400rms (1/2 a 800.4) and a audiocontrol eqs and some other stuff as well. But i just don''t see the results that i thought were going to happen.

My friend has 2 JL 15w3's. His hits deaper but nowhere near as high.

The Vega-154 and 158 exhibit superior excursion with an Xmax of 19.1mm/.8" (one way)! It produces massive SPL in the recommended vented enclosure and, contrary to rumor, performs wonderfully in a 1.75 ft^3 sealed enclosure; you should SEE and FEEL the speaker go at 20Hz!
Cosmetically the speaker draws considerable attention with its inverted kevlar cone and the classic Cerwin Vega red surround.

As with other 15" drivers, the 158 tends to merge quick bass notes into a fuzzy blend; the crispness as found in a 10" driver is lost. The speaker is more suitable for those listening to hip-hop style music characterized by long deep notes or for those wishing to rattle their friends' cars with massive sound pressure levels. Also note that the glossy black cone tends to haze slightly if left in the hot sunlight.

Paid $135.00 new. Check out eBay as these speakers are constantly going at great deals. Note that the warranty may not be applicable on Internet sales, as such. I would highly recommend this speaker: it has performed wonderfully and reliably for the past 5 months and reaffirms Cerwin Vega's ability to produce an earth-shaking sub. There's simply no better bang for your buck.

Not as clean and clear as it's competitor, the JL Audio 15W6, but capable of increased power handling and output. Will out-hit any single 12" driver or dual 10" drivers given proper power.

HITS VERRY HARD AND LOW IT'S PERFECT FOR SUV'S

HOW BIG OF A BOX IT NEEDS MY ONE 15" NEEDS 3.5CU FEET OF AIR SPACE

I WOULD RECOMEND THIS SPEAKER TO ANYONE IF YOU GOT THE ROOM FOR THE BOX.
I PAID 249.00 FOR MY 15" FROM CRUTCHFEILD

THERE IS NOT A SUB I HAVE HAD LIKE IT

very very loud. I used them for DB drag racing comps.
I was hitting 148 with just 2 15's, and the ports were not even facing forward. We tested them with the ports facing forward and it did a 152.3 at the dash. (it just did not look as good)

they need a lot air space

I got a special price of $160ea. I would recommend them to anyone who wants to win in SPL comps.
