Just got subs and an amp... I need help!!!!!!!!

[Unregistered]

I was just given 2 MTX Thunder 10"ers and a Jensen 250 watt 2 channel amp. I hooked them up with a High/low converter stealing a signal from one of my 6x9's. They sound bassy, but really sloppy, not even close to the guys I know with only 1 10" sub... It even sounds like they punch in about 1/2 second off beat!!! Why? Remember... I have NO idea about ohms and stuff like that.... so try to make it simple... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I also want to amp my 6 interior speakers as well.... What should i do??

P.S> I have a TOTAL limited budget, so whatever you do, tell me how much $ it will cost too...

Thanx a lot!.

If all wires are hooked up correctly, and you don't have the gains at full, then this just may be the sound that you are going to receiving from this set up. I have a friend who just tried to run an amp and sub from a line out converter so he could use his factory HU. THe sound was so horrible that he just pulled it all out again. My only other theory is that you are only using the signal from one 6X9. If I'm not mistaken your amp most likely requires a left and right input. This could be why your sound seems to miss a beat. I have very little experience with using line out converters so I may be wrong.

i agree with natem33... all amps (even mono amps) require a stereo input. if you only have one channel of sound going into the amp, you are missing the other half of the beat!

If you can only get signal from the 6x9 then try and run your subs in parallel this putting the power into one sub then taking another wire and running it from the firs sub 2 the second sub if you have any questions email me and I will try 2 clarafi..

i don't know about it being totally necessary to have stereo in although it is a much better idea, some amps only use the right channel if it's putting out a single bridged channel, and bass hits don't hit left to right so that shouldn't make it off beat either. but if you're using a line converter, sound quality takes a serious nosedive, it's meant for convenience of not having to buy more components such as a HU w/ rca outs and running wires and cables etc. if you want to power the rest of your interior speakers, you should buy new speakers that are meant to be amplified otherwise you'll just get louder, but worse sound. generally speaking, there are two types of interior speakers, ones that can run off maybe 40 some watts per channel that an aftermarket head unit can put out, or 80-100+ watts that will require a seperate amp. the reason being the higher wattage speakers have bigger magnets requiring more power to run them, which in turn makes louder sound. prices really range a lot depending on what level you want to take your sound to. and one thing as a guy that a lot of friends and friends of friends come to to ask about car audio, never ever ask "Whats the best?" "What should i get if i want really good sound?" those are the broadest and most annoying questions. the best thing to do is do a little research on sound quality vs pricing which are ALWAYS proportional. a little knowledge will take you a long way, and the more you learn, the more fun this whole car audio thing gets

just to clarify... even if the bridged amp is only using the right channel for mono output, it is combining the input of both the left and right channels for the mono output!

if the studio that mixed the recording has put the bass hits mostly on the left channel, and you are only using the right channel as an input for your sub amp... you will be missing all the left channels bass input. and visa-versa.

hmm.. i didn't really think of that, i'm not too sure about whether they mix the channels for mono operation or not, most amp manufacturers aren't too descriptive about that part. but about the bass hits, 95% of the time, its on both channels equally, maybe slight but hardly perceptible variations, some midbass drums, like snares or off beat drums may run seperately but most of the phase shifting and panning happens on mid-high channels

I'm the guy who originally posted this Q for all you pros. I'd just like to thank you for taking the time to help me figure out what the heck is really going on with my system. But a question still remains..........

I will post it on a different thread...... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
