Probably a good sub, not a good match for MTX Terminator Dual 12" Subs
935723
I won't say it's bad, because it's not, but this is being advertised as a recommended purchase alongside the MTX Terminator Dual 12" Enclosed Subwoofer. With those subs, this amp goes into protection mode quite a bit (it's not powerful enough). But I assume that for lower power subs, this probably works fine. For the MTX subs, buy the Kenwood eXcelon x500-1 1000 watt monoblock amp.

The PSW sounds fine, but has some questionable electrical design choices. I purchased a broken PSW108 from a local retailer, and have repaired it. The amplifier chip (TDA7294) was shorted (and getting quite hot during operation). The speaker driver looks nice and sounds alright, though I wish that it could go a little lower frequency (than the specified 35 Hz).

While examining the circuitry, I found a few things were done out of cost concerns which I do not like. Firstly, the power supply is unregulated. This could introduce some 120 Hz noise in the output and will likely cause the output power to reduce at high loads... Next, there is not a proper crossover for the speaker-level inputs. The speaker-level input and output are directly connected together, meaning that the low-frequency components are passed to your speakers in addition to the subwoofer. Thirdly, the left and right signals (both speaker and line-level) are connected together with tens of ohms between them. This could easily reduce the stereo separation of the audio (mixing the left and the right together).

As I said, the subwoofer I purchased had failed. I couldn't find the reason, but I'd imagine that either the speaker was played too loudly (overheating the amplifier, though it's supposed to have thermal protection), or the power line had a surge.... I replaced the amplifier with a TDA7293 (slight upgrade), and we'll see how long it lasts.... I'm using my receiver's LFE output channel so that the main speakers output is properly high-passed.

I used the 10 inch Polk sub for many years. I love that sub BUT it struggled to maintain clean clear bass for certain movies with a lot of action, explosions, ect. I can honestly say those 2 extra inches made a HUGE difference. This 12 inch sub vibrates my walls with no rattling and no distortion. So if you have the extra money grab the Polk 12 inch sub. You will be a lot happier in the long run.

Have it on (1) Rockford P2D4 12'' Sub at 2ohms and it slams.  Using Boss 8ga wire set too, all that it needs ($12).

I put this sub in a band pass enclosure and the voice coil locked up after 15 minutes. I was running the right gain and everything. Sounded good until it went to crap though haha

I've had these in the front doors of a 97 maxima for a few months now. They are running off a new jvc kwr900bt which has a totally decent amp section for a head unit. they are paired with their coaxial counterparts in the rear deck. installation instructions were a little confusing as they are pictorial and there a pile of parts in the box, but I figured out what they were trying to say easy enough.

now for the important part: how do they sound?

well, disappointing to be honest. I was hoping to have a decent enough sounding setup with new speakers and head unit without having to go through the time and money of installing amps and a sub. these speakers are completely void of any bass whatsoever. I have tweaked the eq trying to coax anything low out of em, but it just ain't happening. I have the same head unit in my wife's pathfinder and she got my old jl audio xr components and her car sounds amazing (for the system). the jbl's are clear and, while a little on the bright side even with the tweeters at the -6db x-over setting, not uncomfortably so. they do play very loudly without distortion and are very crisp.

now, having said all that, I think these speakers are going to end up being a great compliment to the right subwoofer once I find it (or them). I will have to find something quick that hits hard but with enough excursion to dig deep because it is going to have to handle everything under about 120hz.

so, I guess my point is this: if you intend to build a system with subs these speakers will pair nicely but you'll want to be very careful in your sub selection. if you just want to replace your factory speakers with something a little better, these might not be the speakers you're looking for, unless you hate bass.

will try to update once the system build is complete.

I bought these subs from abc warehouse and they're really impressive. these subs match up with my friends 600+ dollar system. I have mine in a ported box and my rear view fell off the second day i had em.

Great sub but get a real box for it, it will destroy a prefab.

DOES NOT FIT MOST NAME BRAND SUBS ON THE MARKET TODAY. Do not buy!

I like it, if you use a better power supply it works well. I would buy more.

the big down fall is the crossover is a joke, and the sub control is completely independent of the master volume.

The bazoka tube doesn't seem to have a lot of "bass" thump for having 2 - 8" speakers and 2 tweeters for the mid-high ends. I am going to call Bazooka and see what's up ....

I found some nice speakers at a thrift store so i needed an amp. This one fit the bill and now i have studio speakers for my mostly thrift shop computer. This amp gets way loud and I havnt even been able to test its limits yet. The subwoofer out is very powerful too for my 50watt sub but it gets distorted at more than 1/4 the way up.
For what i needed this for, it fits the need perfectly and I would totally buy it again if i needed anther amp.

Update: The subwoofer out was horrible no matter the subwoofer i used. Dropping to 3 stars.

Problem with this was that I had two 25 amp fuses that came in this to begin with. it was okay, I started tuning and figuring out what I could do with it, and powering my Sundown e-15 (" rms 500") bridged I popped the 25 amps. so replaced it with 30 amps and It would overheat to the point while running it that it would of course stop working. so I got the new gto 751 ez from jbl.. for being cheap for one and two for being at least monoblock. but the darn thing is putting out twice the bass what this pioneer would. I even have videos on youtube of that. pioneer used to be a great label in terms of subs but now they are just meh. this would be great powering 2 of those 12" 60 dollar wal mart subs. I think they are what 250 max rms? lol I haven't been done that aisle in about a year so I don't remember. looking for a cheap 2 channel this is good for you. looking for a good single channel amp for one sub, unless its below 400 wat rms I recommend you spend a little more money

The sub works well...but was hoping it would add more "fatness" to my PA.  Using one sub with two Behringer 12' powered speakers.  I may go with two subs to see if that does what is needed.  This is a good price for a good, powered sub.

I seen this subwoofer at bestbuy for about 400$ + tax, then I checked on amazon.
Purchased this from amazon and loved the bass for front room 20-18 room.
Sad thing is, this sub just died one week after 3 hours of use.
No lights on the back of the subwoofer, reseated all the power cords and played with the switches.

This is a great subwoofer if you are the type of person to walk into bestbuy and listen to this and a klipsh and have no clue about bass or audio aka the typical consumer....

So I returned this item and bought the Mirage Omni S10.
The Mirage weighs more and has more deeper lower bass than this Polk by far.
I will not buy another polk sub after this, must have been a crappy built amp that polk decided to use.

I am happy with the Mirage Omni S10.

Amplifier has a lot of power. Im pushing twin 12 inch pioneer championship dual voice coil subs,  at 2 ohms.. amp is at 40% gain. Slamming s***. Subs are maxed out. 1200W max on the subs.

Not bad, but subwoofer still lacks some punchy bass.
