So, I'm looking for a low cost 4 channel amp. I've been out of the car audio loop for almost a decade so I don't really know if there's been any technological advances since then and what brands I should be looking at or avoiding.
So anyways, the vehicle it's going in is a 1995 Jeep Wrangler. Interior is currently stripped out so I can throw some bedliner in the tub. While everything is out, I figure it's a good time to upgrade the audio and rewire everything (For example, if I hit a bump sometimes the driver's channel cuts out completely). It currently has 4x6's (unknown brand at this time) in the dash and 4" Radiocrap speakers in the sound bar overhead. I'd love to be able to actually hear some tunes while driving down the highway with the top off, 33" mudders, and a loud exhaust.
So, for speakers I'm eyeing these Polk DB461s (40 watts RMS) for the dash and possible these 6.5" Polk DB651s (60 Watts RMS), these 6x9" Polk DB691s (100 watts RMS) or these 5.25" Polk DB521s (45 watts RMS). I need to pull down the sound bar and look to see what I can fit in it (or build a custom sound bar, which I have no hesitation doing, just time consuming). The 5.25" shouldn't be TOO much of a hassle, but the 6x9's will probably require a ton more work.
So what do you recommend I look at for amps? Low cost is key here. Jeep wranglers with soft tops are the absolute easiest thing to break into. I don't want to be out $100's if it goes missing on me. Back in the day I had a US Acoustics USX-4065 and loved it. It was an exceptional value back then. There's one floating around on Ebay right now but I'm hesitant to buy electronics that could be over a decade old (if it was a bit cheaper I'd pull the trigger). Internals get old. Another thing is the SQ does NOT have to be exceptional. At highway speeds a slight distortion won't kill me. Crackling might, and I don't need something that will burn up and die on me. Water resistance would be a plus in case I get caught in a down pour, but I'll be installing it underneath the rear seat.
