Profile's Baja amplifiers combine quality design and features into an economical package that puts power and control at your command. The Baja HA1040 4-channel amp delivers 80 watts RMS by four channels, or 225 watts RMS per channel when bridged to 2-channel operation— plenty of juice for powering your system.

Profile designed the HA1040 to power full-range speakers in the front of your car while running a sub at the same time. The built-in variable high- and low-pass filters allow you to tailor the output for your system's particular requirements. You'll also find a selectable bass boost for the rear channels and treble boost for the front channels.

Preamp-level inputs allow easy hookup to aftermarket receivers. There's even a set of preamp outputs to relay the signal to another amp in your system.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Inputs and Outputs Notes

Gold-plated Terminals: The HA1040 features gold-plated speaker and power terminals and RCA jacks for maximum signal transfer and corrosion resistance.

Remote Turn-on: In addition to turning on and turning off the amplifier via the head unit's remote output, the remote turn-on also operates the reset circuit for the amplifier's protection system. The remote turn-on lead must be connected to the head unit in order to reset the protection circuits.

Met My Needs

Written By Craig, Phoenix, AZ on Tuesday, October 21, 2008

Crutchfield Customer Review (What's this?)

With other reviews claiming heat issues, I mounted this in my boat with risers which gives the amp 360° air flow. I've got 6.5" marine speakers 2x2 in series on channels 1&2, and bridged the Kenwood w3011 12" sub on channels 3&4. I was very impressed that my neighbor complained when I was dialling in the amp. This amp has high/low pass filters built in, high/low cutoff dB levels, dB boost and gain on each channel pair, plus overall gain. This single amp had enough to power my whole system and now I can hear my tunes at cruising speed.

Big disappointment

Written By nopepeno, Hamden, CT on Thursday, October 16, 2008

I've being experimenting with various amps and speakers for the last year and a half and today I finally got my sound the way I always wanted it, but before I could finally accomplish this task I had the degrease of trying this amp, I am not happy with the way this amp amplifiers sound, the low frequencies are cut off, so if you want to have a balanced sound (median sounds, high sounds and lows) do not get this amp, it is a waist of time, and the biggest pity is that you might never know the things that you are missing from your speakers. my opinion is that This amp is NOT GOOD.

Plenty of Clear, Crisp Sound and Bass

Written By Stephen, Annandale, VA on Saturday, February 09, 2008

I just got this Amp, installed it to my upgraded 4 infinity 6012si 6 1/2 speakers in my 07 Hyundai Sonata.This amp provides plenty of power, easy to install and connect.It has a bass boost which I do not recommend you use, it simply adds more distortion to the sound, also the high pass unless u want to drive some tweeters.For more bass simply match the gain properly and use the bass that comes with your stereo and u get great sound or get a sub.It does not heat that much at all, the install manual is excellent and straight forward.One thing they do not mention is that there are 2 gain settings, one for the 2 front spkr and the other for 2 rear spkr.When adjusting the gain use the fader to select the pair spkr in the front to fine tune the front only, the repeat the same for the rear and then put it back in balance and you got AWESOME SOUND!!!!! BUY THIS AMP good for the money.



Eh....

Written By Gary, Knoxville, TN. on Monday, December 31, 2007

Was great for the first three months, though it got hot enough to melt the bungee cords holding it still. Eventually melted all together. Had it running two JBL 6x9's at 100x2 @2 ohms, and a Sony sub at 250 RMS @ 4ohms, with a 1.2 Tsunami cap. Lasted almost 90 days and quit. Out of stock now.

WOW!!

Written By carlos, West Palm Beach,Fl on Tuesday, August 07, 2007

I just got this amp and have it hooked up to a pair of 6 3/4 infinity components and a pair of pioneer 6x9 5 ways, this amp is awesome!!! setup was very easy. I did have wicked alternator whine and ofcourse, the crutchfield tech was A+++++, he actually sat for the better part of an hour as I went through my system and helped me find the problem (bad rca cable), the purchase was very very easy, I called crutchfield and the rep helped me choose an amp and explained EVERYTHING with TONS of detail.

Given that crutchfield is a bit more expensive than others, but they only sell quality gear and the customer service is unbeatable!!!

From now on I will only but from crutchfield!!!

Great amp and the price us good and it comes with a 2 year warranty.

Exceptional value

Written By Chris, Mt Laurel, NJ on Monday, July 30, 2007

This amp was perfect for my setup. Running Infinity components in the rear and polk components in the front, these provided them with plenty of consistent, strong, clear sound. The quality of sound and amount of power this amp puts out is on par with amps hundreds of dollars less at a suprisingly cheap price. Although the controls are limited compared to higher end amps, the "bang for your buck" factor is phenomenal.

Well Worth it!!!

Written By James, Bayside, NY on Tuesday, June 26, 2007

This amp is great. I have it driving four Polk 5/1/4" speakers in my 2007 Sonata, and it it rocks! A great buy for the money. Way to go Cruchfield!

Great

Crutchfield Customer Review (What's this?)

I just installed this amp in my 2002 Jetta, I have it powering Polk Audio DB6500 components in the front and Polk Audio DB6750 components in the rear. This amp gives them all the power they need, very clear highs and mids. The amp does get a little hot but not nearly as hot as other amps friends of mine have. You cannot beat the price and 2 year warranty. Plan on getting a Profile AP1200 to power 2 10" Polk Audio MM 2104 subs.

Great Value, Good Performance

Crutchfield Customer Review (What's this?)

This AMP is powering a pair of Infinity 6010cs's (front) and a pair of Infinity 6012si's (rear). Got the AMP based on reviews of the 6010cs's needing external AMP. The HA1040 does an excellent job of powering both 6010cs's and 6012si's. Car system never sounded so good!! Using a JVC KD-G320 as head unit. No complaints and have had it installed since October 2006!

Mehhh

Written By Matt, Westminster, MD on Tuesday, October 31, 2006

This amp gets pretty HOT. But never cut out on me. Has some good features on it. But one thing completely blows my mind. I didn't use it for about 7 months and stored it in my room. Plugged it back in my truck and the thing blew 4 fuses. Called profile and said my warranty should fix it. A product goes bad from sitting in a drawer for 7 months? That just doesn't make sense to me. I wasn't impressed, nor was I disappointed from the HA1040, but the whole thing with it magically dying is mind blowing.


[NOTE] Crutchfield of course will provide excellent customer service like it always does :)

Great product, good value, good perf...

Crutchfield Customer Review (What's this?)

My Setup: 2000 Toyota Sienna CE, 1 pair audiobahn AS50Q 5-1/4" 2-way Speakers, 1 pair Polk Audio db 570 5"x7" 2-way Speakers, 80W x 4 @ 4ohms, speakers installed to stock locations.

After nearly 4 weeks of use, I've found this amp. to be quite adequate. Connection and tuning were super-simple, with the help of Crutchfield's guides of course. The control settings and connection terminals are easily accessible and simple to use. Although I'm not yet taking advantage of the full power this amp. has to offer I haven't noticed any overheating issues, or other problems that would inhibit the overall performance of the unit.

This Profile Amplifier's low price, coupled with Crutchfield's Superior Service made this amp. the perfect buy for me!

Holler!

Crutchfield Customer Review (What's this?)

Great Amp! Great Quality! Powers up 2 kicker 12 inch subs with no distortion. Even when the subs are turned all the way down it's still very loud. For the price profile amps are worth it, they last the longest and sound the best!
