great amp a litte large

The amp is working great i have way more than I should on it. I have 4 6x8s 2 6x9s 4 seleinum 250x and the amps going good no cliping or nothing. I like it loud, i will probably buy a 2nd one at this price. It's a steal.

Great Amp :)

I Have this amp powering 3 sets of my Alpine Type R 6x8s, it is GREAT, they sound clear and the amp has amazing power output, i can hear the words over my BTL 18.

Good sound great price

Using 2 of these amps, one on an atv and one on a rhino sidexside. They have held up very well. Not the best environment for an amp, that being said I will buy them again when these die. Any amp that last a year with me is a pretty darn good amp!

Intense amp!

I bought this amp to push my rear end which consists of 4 very powerful midrange and midbass drivers. Each asking for 150wrms.

I bought this amp initially to play just two of these drivers, figured i'd bridge it and get some nice power or something along those lines.

For the heck of it i wired up the amp to 2 ohms and tested it out with all 4 speakers and I have no regrets for the price I paid!!

This amp has the sound quality of rockford for the price of an amp you wouldn't think twice of buying.

Just one won't match up for compitition use but the sound quality is beyond impressive at max volume with the gains set correctly there is no distortion on the system and by itself produces mids that overpowers both my RE SRX tens if untuned.


Great purchase!

AWESOME AMP POWERBASS A++++++

i use this amp along side the matching 1000d mono amp..
The 4-Channel pushes all 3 yes 3 sets of PowerBass components..and it powers them beautifully..never gets warm and loves the 6 volt preouts from my epicenter..

Powerbass is a legit company..I was leary at 1st..but I did some research..and decided to try them out...I'm not regreting it either..
The 1000D is pushing a custom built 12" woofer gives it a real 1000 RMS.. amps are powered by a 220 amp alternator 0 gauge wire..and 8 and 4 gauge into amps..and 2 shuriken BT100S.. everything o scoped out..and its sooooo clear its crazy..

buy powerbass!!!

Great 4 channel for cheap!

Pros: This thing pushes all 6 of my alpine 6x8s with EASE! 1 in each front door @ 4 ohms each getting 100 RMS. 2 in each back door getting 100 RMS each @ 2 ohms.

Cons: None

Outstanding amp

The following review is for a previous version (ASA-600.4).

This is the third amp I've had in my Accord using the same speakers, with each being better than the last. The difference between my first and my second 75 watt PG was big, but the difference between the PG and this one is huge. All frequencies are clearer and punchier. It really brings out the potential of my speakers, I never thought they would sound this good!

I also like the looks - very clean, no stupid lights or visual idiocy.

5 stars for durability just because I've never had a problem with it.

Great Amp

The following review is for a previous version (ASA-600.4).

Got this thing, installed it later on it in the day, sounds WAY better than it did. This thing doesnt feel cheap at all, its very heavy and solid. Wonderful amp.

PowerBass is awesome!

The following review is for a previous version (ASA-600.4).

Setup:
2003 Toyota Camry XLE
JBL Stock Head Unit
2 Infinity Kappa 6x8 682.7cf in front doors
2 Infinity Kappa 6x9 673.5i in rear deck
2 10" Kenwood KFC-W2505 Subwoofers
2 Channel PowerBass ASA400.2 on the subs
4 Channel PowerBass ASA600.4 on the Infinity's

I've had a lot of luck with this setup. The ASA600.4 amplifier was the last piece and it was well warranted. The Kappas sing to perfection and are not distorted even if I turn that dial all the way up. It's small, plenty of power, and doesn't overheat or have shut off issues, it just does what is asked and that is play my music at a painfully loud level.
