best bang for your buck

I have 4 8" planet audio ac8d subs they sound better then the fosgates they replaced

BIG BANG for the buck!!!

I bought this sub to replace the blown stock woofer in my 01 Suburban. I took the outer cardboard ring off the stock woofer and put it under the AC8D so the magnet did not bottom out in the stock enclosure. I am truly shocked how good this thing sounds. I would recommend this to anyone looking for some cheap bang. Clear deep and tight bass, no muddy sound at all. If you were like me and debated over so many options....This is it!!!!

1600 Watts?

The sound is crisp, and the range is incredible! I had just replaced all the speakers and feel like I now have a rolling concert hall. However, the only complaint is that I thought 1600 watts would be much louder. But, hey! I only have less than $400 in the entire system, and I've got blue tooth connectivity, iPod connection, etc. overall, this is amazing!

Get's the job done

I just purchased a pair of these subs and put them in a sealed box w a little poly fill in and they sound GREAT!!!!!. You really can't beat the price on these. They are being pushed by a Hifonics Brutus 1200 watt amp and are bridged. So far so good. Works great in a smaller car. Mine is a VW Karman Ghia.

great subs for the price

I bought 8 of these and have them in a custom built 5.5 cubic foot box tuned at 21 hertz. These subs are great for the price. I have all them running at 0.25 ohms on 5k plus daily. I'm burping anywhere from 148 to my highest the other day of 151.3 dB on the dash sealed all the way up. I'm going to be ordering 4 more and doing another build. Love these subs

sub

Great Value for price

This sub-woofer gets the job done! It sounds great and looks great. I bought this for a replacement of a Sony sub-woofer that started to blow and for 35$ it couldn't get better. I would highly recommend this product.

great value

Great price for a great product sounds really good for a 8 in sub

Good value.

For the price, these are excellent speakers so far. Just got the right size sealed box according to specs and thy work really good. Time will tell if they are durable.

Great value

I love these little guys. I have two in a custom box I built for my truck with a 1000 Watt Punch amp driving them and they hit harder than I would have believed. I wasn't expecting much for the price but I was very pleasantly surprised by their sound. I think they are actually sounding even better now that I have a few hours on them. Nice looking speaker, too, well worth the crazy low price.

Stitched leads and a solid cone,but as usual the ratings are optimistic,a good little sub for the money!

Great value.

I installed 2 of these 8 inch planet audio speakers in my 1971 Mercury Montego along with 2 rockford fosgate 3 way speakers and 2 boss 3 way box speakers.Powered by a 500 watt rockford fosgate amp and a kenwood kdc-mp165u stereo.This little system has plenty of power and bumps with the best. $360.00 invested in the whole system.All purchased from Sonic Electronix. Great value and prices.Fast shipping.So far very happy with the products.

great for the money

very fast shipping and mounted in a very small box in my trunk.
the bass isn't over the top. ( if I had a better bkx I'm sure if would be louder ).

it does what I needs to do and I'm very happy with this purchase

Planet Audio AC8D

Absolutely great little 600W 8" Dual 4 ohm Subwoofer! These little guys hit! I can only hope they continue to do so!!! Replaced 2 old ones in my Tahoe and couldn't be happier. Drove my truck all week just listening to the beats!! Back to driving my car this week and seriously missing them! I'm picking 5 on the Durability below, but I seriously have no idea if that's true... It's only been a week.

Awesome price

Great quality sounds had to fab a little for my suburban cause magnet to long but I made it work sounds great.

Great Value!

I bought this to replace my blown factory sub in my 02 Tahoe. It fit great and sounds gopd for what it is.

Great sub!!!

It sounds good and very powerful to be an 8" sub, we used it to replace the stock sub in a toyota avalon and also replaced the amp and sounds great, planning to get another for my expedition too.

Phenomenal Value - Great Boom for the Buck!

I installed this into the factory sub location in my 2001 Suburban, transferred over the spacer ring from the stock "sub" and cut the plastic grille so the cone doesn't hit it under high power excursion. Powered by the sub channel on a Planet Audio 5 channel amp under the middle row seats, this sub hits amazingly well for such a small sub. The interior volume inside the Suburban is huge and yet it fills it extraordinarily well. The bass is detailed because the enclosure is sealed, but the volume at which it plays cleanly is well beyond my expectations for such an inexpensive and small sub. Cannot beat the value of this little powerhouse!

I dont usually do reviews BUT!

So I bought this sub expecting nothing much at all. BUT DUDE! This thing kills both of my kfc112s kenwoods!! And I have two! This is seriously best bang for your buck deal you will ever find! The only con I have is that it dosent hit lows to good. But I mean its an 8. Its for punchy bass. Not super low stuff.

Planet Audio (Boss) Must have made these T/S params up outta thin air

I build SQ systems and have been on the hunt for a good Infinite Baffle 8" subwoofer for a build. Part of this process is testing T/S params of tons of different drivers before break in then after to obtain data on how they'd perform in a certain enclosure. The parameters Planet Audio specify for this subwoofer aren't even close which yes, parameters are variable dependent on atmospheric conditions, they don't change this much though. I will say that this is an excellent candidate for an infinite baffle.
Here are the measured parameters, 70 degrees F with very low humidity.
Both coils (p)
R(e)= 1.81
F(s)= 56.22
Q(ts)= 0.7288
Q(es)= 0.88
Q(ms)= 4.241
L(e)= 0.2631 mH
M(ms)= 52.35g
V(as)= 11.33L
SPL(1w/1m)= 84.58

Both coils (s)
R(e)= 7.202
F(s)= 56.16
Q(ts)= 0.7921
Q(es)= 0.9494
Q(ms)= 4.781
L(e)= 1.067 mH
M(ms)= 42.52 g
V(as)= 12.16 L
SPL(1w/1m)= 85.45

And because someone will ask, here's pre-break-in, fresh out of the box.
R(e)= 3.416
F(s)= 53.7
Q(ts)= 1.549
Q(es)= 2.017
Q(ms)= 6.671
L(e)= 0.2627 mH
M(ms)= 53.07g
V(as)= 10.65L
SPL(1w/1m)= 81.02

Small thump at best

I bought these guys to fit my Galant, and I must say this is just the punch n bass I was looking for.

Better than expected

Better sound than expected for the price. Doesn't hit as low as I would like but it is recommended for a sealed box. Mine is ported. Wired 4 of them to 1ohm (series/parallel) for my mono block planet audio amp. It makes a great quick punch in higher hz and hits great down to 50hz
