So I've been doing quite a bit of research to try and figure out the best amp for my particular needs, but I'll be honest; I'm a bit confused by the differences between amplifiers, the customizations people are doing, et al. I ended up purchasing a TDA7492 amp from Parts Express and it's working alright, however I am getting some distortion at higher volumes (with the gain set to low) that I don't care for. I'm hoping you fine folks can point me to a better amp that will suit my particular needs. Those needs are:
- Powered by an EVO2 battery that puts out about 14v fully charged but will run around 13v most of the time.
- Input source is an iPod. Volume controlled by the iPod.
- No onboard volume control, EQ, gain, etc is required.
- Will be driving a pair of 4 Ohm Infinity marine speakers
Ideally I'd like a simple amp that's pre-built, though I'm open to DIY if it's required to achieve my needs and am decent with a soldering iron.
Any thoughts?

I would go with hifimediy t1-m. It has a wide range of voltages it can handle and can utilize your 14v battery. It will also work with your 4ohm speakers.
Hifimediy T1-M TK2050 9 - 24V

Looks decent. For the price, I'll definitely give it a try. I also picked up a step-up voltage regulator which I'm going to toss into the loop. Never used one before and I imagine it will cut down on my battery life, but I can afford to lose some longevity. Anyway, we'll see how it comes together when the parts arrive. Thanks!
sounds like your input impedance is off. is there anyway you can increase your gain at the input? like with a headphone amp? or that battery may be too small. these last me 11 hours on a TA2020: Amazon.com: Rechargeable 12V 7AH Sealed Battery: Electronics
that amp should be clean and bumpin.

I was looking at getting the Hifimediy T1-M. It is showing about 14.5 Watts into 4 ohms with 12Volts while the lepai ta2020 shows about 20 watts into 4 ohms. Do you think the Lepai data is inflated or do you think it would be louder than the HIFIMEDIY T-1 M? I am going to be putting this into a "Boominator"
In my opinion they are both around $25 ea correct?, but by the time you add some freight etc... you know it not that expensive to better quality amps.
I cannot say one is better than the other without listening to both, but looking at the electronics on the Hifimediy, I can guarantee it will be better than the Lepai.
Depending on the sensitivity of the speakers hooked up, I would even try to go better than that. I Highly recommend something a bit special like the Amp6 from 41hz, which was about $115 delivered for 2, huge difference.
Lepai is cheap crap really. (I do use one for my TV stereo upstairs, and 1 in my workshop)
but they are pretty low sensitivity.
When you build a boominator, the most Expense is your time, so spend up on the components, you'll hear it...

I have an ADS Powerplate 40 I would let go of for $75.00 and a ADS PowerPlate 80 I would sell for $100.00 you will not find a better Amp that ADS. They were some of the best made . They actually built the first car amp that incorporated a Switch Mode Power Supply .
I also have a Harmen Karden 20 x2 I will sell for $40.00.
If you want good sound get a good amp a cheep chip amp will not even sound close to as good as one of these
