Question: how does this product mount in a box?
Document: If your looking to buy an alpine speaker get it from these guys theres a box in a box ,no scratches or anything very good product I boughgt a previous alpine from another seller n it was horrible packaging was ripped and the speaker looked used when I had bought it new
Sounds great!! Bass is very clear and deep, I used a sealed box and an Alpine 500w amp, great set up for low cost bass.
Great sounding subwoofers, have a really nice low bass to them when given the right box, I even have these subs underpowered by quite a bit and they still bump hard. Great purchase.
I bought this subwoofer to replace a blown Alpine SWS-1243D. I stuffed my sub box with polyfill before I put this bad boy in. It really hits hard with a cheap temporary West Coast Customs amp that I had laying around (My Alpine MRP-M500 amp blew....starting to question the quality, maybe operator error though). I would recommend this sub to anyone considering it. It adds that missing liveliness to all music in any vehicle that this'll fit.
wow what an improvement. This is the first sub I ever installed in my car so I can't really compare it to anything else, but the sound quality is excellent. It can go very loud, much more than I needed.
sounds great hooked up in my blazer on a crunch 1600.2 amp. it sounds so clean and crisp. and the bass notes it produces drop super low. sounds better than my 2 10s i had. really like it. im getting a second one soon hopefully. highly recommend.
i recieved this sub from SONIC ELETRONICS with no serial # so this could only mean a few things 1 it is a fake. 2 it is a gray market item. 3 it stolen. i contacted the seller to ask about the warrenty and serial# missing, the responce is sorry we (SONIC ELECTRONICS) handle the warrenty. but you can send it back if you want! what i want is a lagit item with a serial # so i can claim it gets stolen or lost.
i put 2 of these in a customers vw passat on a 1000 watt Polk amp wired down to 1 ohm. he wanted his car loud, he got it loud! im pretty sure we could of went with a bigger amp no problem but he didn't want to strain his stock alternator any more then he had to.
So first I was supper disappointed in this sub. I had it hooked to a pioneer 800 watt mono amp pushing 400 rhm at 2 ohms. I knew this amp was good as I used it on my kicker cvr. Well I installed the amp and it did not sound good at all. Low bass, and it couldn't hit the lows at all.after double checking all my connections I decided to buy a pioneer 3600 cd player in stead of this crappy clarion one I had.
No it was horrible and the item was completely broken when I got it&#128078;. And whoever was selling this knew that.
Answer: There is a rubber seal that goes around the face edge of the sub. It comes off to reveal the screw holes.
