  1. Purchased directly from DS18 online store. I never could find out for certain what kind of quality DS18 as a brand really was but I had assumed it was a newer brand catering to the mid tier market maybe akin to RF or Kicker's mid products at least. I didn't find any particular statements for or against the brand online outside of typical consumer reviews which I always ignore those because people are stupid so decided to give them a shot since I was looking for a really small 5 channel amp and there are only so many amps of this output range in a micro size. Pro's: The amp sounds really clean. Definitely a cleaner, clearer sound quality than my JL Audio MX280/4 amp I was using just prior. Meh's: Design, aesthetically it's nothing I would want to show off. I had a hard time turning the allen screws for the speakers, they use the angled design but the included allen wrench makes it real pain. Honestly you need an allen tip with a handle because the screws are so small and requires quite a few turns to the point of the screw almost falling out in order to get enough space for the 12 gauge wires. Con's: Didn't take long before a channel blew. I initially tested the amp with the gains down because it was late and worked fine, sounded good. The next day I unhooked the speakers so I could set the gains, took my hand held O'scope and went to adjust the gains but was having a weird problem. I could get a sign wave just fine on the sub output but no signal on the main channels. So I turned the volume down to 10 and put on some music,plugged in a speaker to ch 1, worked fine. Ch speaker popped, there was a slight spark. Then nothing. Ch 3 didn't have any sound at first but at some point it suddenly did. (naturally I chacked my RCA outs and they were fine) Checking again with the O'scope, I had no I thought my scope crapped out on me but found it works on anything else I tested. Channel 4 is an odd one as well. You see I can get certain 4 ohm speakers to work on it, but not others. So my test speaker is an old Kenwood 6.5. It works fine on Ch 4. But my JL Audio front speakers do not, i get no output. My Boss output yet those speakers work fine on Channel 1 and 3. The Kenwood also works on all channels except Ch 2. but the JL's do not like Channel 4 but work on After a couple hours testing, it seemed the right side channel was definitly no longer working. My scope works fine on everything else except those 4 channels which I thought was weird. Channel 4 only works with my Kenwood speaker which it's just a 4 ohm coaxial, yeah I don't get that part at all. So with that I'm not going to rate it. Just leaving the review as is for others to judge. Naturally it seems like some kind of user error but I cannot reproduce any error on my part on any other amp or speaker. I only get those weird issues on that amp and makes no sense to me but I wasn't going to bother with a help thread on it. Instead I just decided to do away with all that gear and go with a really simple, just above stock setup using a Kicker key smart amp to save space and keep a more stock appearance in my car. But the experience left me with a sour taste putting the DS18 brand right there next to Pyramid and Pyle.
  2. I'm doing a down grade so went for a small efficient route and though it doesn't hit like my Sundowns it still sounds really good. Even the bazooka sounds better than i thought it would and doesn't take up hardly any room.
  3. Is it -5 db's? I like a little overlap. I don't think it really matters does it? I know on my O'scope, the 50 hz will clip before the 40 hz does.
  4. Years ago I found a site I could create test tones and change the db but can't find it now. I need 1khz -5db and 50hz -5db. Also will it matter if I convert it to 320kbps MP3? My HU's usb only supports MP3's and I don't have a cd player, it's just a media unit.
  5. Well I'll be a son of a bitch. He used a master level 80 thread resurrection spell.
  6. Lol what? Anyway, fortunately I found it. It's called Aperiodic enclosure but thanks for almost trying. MMATS once made one but it covered the front of the subwoofer but apparently most enclosures of this type use it behind the sub. It appears Scanspeak still makes them but many go the DIY route. I was interested in researching to understand why manufacturers that make under seat subs and other really slim mount enclosures don't use these since it makes the enclosure appear to be 20% larger.
  7. Lol, no, no. It's a membrane, not a radiator. It starts with an A. Like aeropriodic or something but I can't find it's exact name which makes googling info about it difficult.
  8. I think the late 90's, I remember seeing ads in Car Audio mags from MMATS for some kind of product that acts like an enclosure, but isn't. It was like some kind of membrane and my memory might be off but I was thinking it looked like a grill that went over the sub and supposedly took the place of a sealed enclosure. Anyone remember what it was called?
  9. Going to Walmart. Trying to make a street smarts list for survival purposes. So far I got:

    step 1: Dress like trailer trash so I blend in without being noticed.

    step 2: Walk with a hobble and suck in my cheeks so no one stares at me. 

    Step 3: Keep my cart in the middle of the isles at all times while ignoring everyone else.

    Step 4: Pretend to look at some Boss amps with interest while verbally envying those Kicker comps and hope no one notices me holding back the laughter.

    I feel like I'm missing some steps....

      Have a credit and cash in case you end up in the self check out aisle with the small hand written note that says CARD only

  10. Why the reference cooler? They tend to throttle.
  11. There is a sale on this right now for only $99. Sounds really good, i'm impressed. Has 2 speakers for highs and 1 sub along with 2 passive radiators. It has a bass boost mode, you can record voice or even phone calls with it and has many ports to play music from various sources and 2 ways to charge. I havn't tested actual batter life based on volume or anything but says it's 8 hours.
  12. Just to update. I ended up calling my CC bank and did a transaction dispute. I think the bank just ignored it, never got a refund, never heard anything about the dispute. Never got a product either and I made that order in early April. I'm literally out $248.99.
  13. from reddit...all I can say is daamn! Notice that amp that has merged to become one with the back of the seat.
