If I am understanding your post, you put these in a truck and it sounds bad. Then to test, you plugged them to your 4 wheeler system and they sound great. It sounds like you are running them directly off the Alpine. If so, then you lack sufficient power. They have an efficiency 88 decibles so an amp is a must.

Okay, that makes sense. But I am still confused because the amp hooked up in my truck is 250 watt rms and it is hooked up to the alpine head unit. Should I try put in a more powerful amp?
The speakers I installed say the power range is 2-50 watt rms and I have 4 installed in the truck, plus the stock bose tweeters and an 8” or 10” sub not sure of the specs on it. Also the alpine head unit is pushing 18 watts across 4 channels. The previous owner of the vehicle had the sub, amplifier and head unit installed at an audio shop. I am starting to realize all the speakers distort including the tweeters when i try turning the volume up. Any help is greatly appreciated!!

The amp you have is not a voice amplifier, it is a subwoofer amp that can only play up to 200hz, and is only powering the subwoofer. Since you do not mention another amp, I deduce that the speakers are connected directly to the Alpine radio. As you mentioned, 18 watts rms per channel is not bad, but only with the right wattage speakers. If you had some in the 10-50 watts rms, 4ohms, minimum of 92db sensetivity, you would be ok. But the speakers you currently have are better suited for high power systems. If you amp them, your sub stage will be drowned.
Like stated above, the distortion comes from too small of an amp powering too strong of a speaker. Best bet is to change out the speakers for some with above specifications. I would stick to two way speakers for they are cheaper, easier to find, bigger selection, and easier to wire.

What voice amp would you recommend for the speakers i have? I cant take the speakers back and I just bought them from crutch field so i might as well get the voice amp and use them. My sub is so strong it feels like my steering wheel is going to shake off the steering shaft when the sub turned up.

What voice amp would you recommend

I would go with the MTX rt604, for it is the one that mostly resembles the one you already have. Plus MTX is a solid brand so performance and durability is not an issue.

yeah I was looking for voice amps and nothing was coming up. Been doing some research and I was only finding people referring to full range amps.

This is my take on you. I percieve you have extensive knowledge regarding car audio and the ability to impart that knowledge in a concise manner. Now you claim you can correct almost every post I have partaken in, then do so. That is the whole point of this entire web site. You have helped others with technical solutions, gotten thanked, and then vomit all over your built up reputation in your next post. You should take your own advice and shut the phuck up when the going is good. In retrospect it seems as if positive input makes you uneasy. Must be a defense mechanism. Stay fresh cheese bag.

Those are not big words, they are concise words. You take time to comment on my posts so out of courtesy I answer. Now go phuck yourself and don't drink and drive.
