Question about Dual Car Audio & Video

Amp or Stereo Cutting out...

I had a low end Sony deck in my car but it didnt have sub out and i didnt want to ghetto it so i bought a cheap Dual deck from walmart which was $50 but it had sub out.
Installed it along with an Kenwood door speakers, mtx amp. and 2 12in K7 2400w subs.
I have had problems with my battery (i need a new one) in the past and one day it just wouldnt start and i didnt have money for a new one so i refilled the cells with battery acid and its been fine sense.
Well anyways, at first listening to music was fine nothing wrong and then now anything above 27 in volume it like cuts off and stops for a second then comes back and then like 10 minutes later cuts off. 
i thought well maybe the amp is turning off? the amp stays on when it cuts off. the led stays on constanty. 
so maybe there is a short somewhere? i pulled the deck out checked all the wires, perfect. checked the amp wires, nothing wrong thats noticable.
maybe the fuses? non are blown and all are brand new.
i read online about the freq. on the amp being set wrong? adjusted it and turned it down. didnt do anything.
what could this be????  im so frustrated, it was fine at first but now its screwy.
i thought well maybe its the battery but my step dad who is in competition audio believes otherwise.
im thinking 3 things which could be causing it at this point that havent been done.. 
1) its the deck 2) its the Audio cables going from the deck to the amp 3) its the battery

What do yall think?
Thanks in advance :)

    the only problem i think im going to run into though is, i couldnt use a lil plug in play adapter to put my deck in. 

    i bought my vehicle, jeep, used and the guy who had it cut the wires to put one in so what did i do? cut the wires on the one new one i bought and wired it in.

    i have experiance with such things but this one as literally got me.

    i just printed a new wiring diagram for the stock wires for the jeep, so tmrw im going to go out there and check and make sure its all in correctly. 3rd time checking the wires but it wouldnt hurt now that i have a reliable diagram.

    im also going to check the audio cable for the amp and also the door speaker wire. make sure everydoor is wired corectly. I did the two fronts but the two rears the guy before me did. 

    i believe the deck is going into protection mode but there shouldnt be a reason to why its doing that.

    i guess ill find out tmrw..  more opinions on this please.

I agree with what you think it might be. I really think its the deck that is bad and you should be able to take it back for a new one. Have you tried unplugging the RCA cables to the amp to see if that stops it? That would tell you if the amp is backfeeding or doing something weird.

Why is my deck not controlling my subwoofer level?

If your Sony receiver has a separate sub output, it probably has a fixed level for application to a powered sub. Your mono amp can only boost the fixed signal level it receives from your receiver. The receiver can't drive that mono amp harder

Where can I have my 15 year old Sony Model TC-WR465 Stereo Tape Deck Repaired? The problem appears to be mechanical. The tapes will not advance on either side of the unit.

Depend on your location and willingness to ship the unit. The cost of the repair must also be weighed in. If you don't want to put $100 into it I don't think most shops these days will want to open it up. Dual cassette deck are notorious for failure due to cheap design. Look around at all the problems. I have been fixing units for 40 years and even at Sony and Sony authorized.
I can look at it at Skywave Tape Deck Repair in Chicago area if you want. Google it.

I want a reliable system.

if you bought that equipment today then your answer is yes your amp will power the subs but if i was you and you want more bass I would go with a two channel amp or even a mono block amp that will be 1 ohm stable and if you decide to do that you might want to get subs that are dual 4 ohm voice coils and run them in series that will get you 1 ohm of resistance

I got the same problem since thair is no sub out for this deck

Hello livinglifeas,

You can connect the regular preamp outputs to a sub amp. Dedicated sub outputs will normally have a built-in crossover whereas the regular front/rear preamp outs will be full-range. Just make sure that the amp you use for your sub(s) has a "low pass" filter.

Hope this helps.

Belt replacement in a sony tc-wr645s tape deck

I have just spent half a day trying to replace the drive belts in my sony twin deck unit , in the end it still didnt work as the the old rubber belt did some damage to the unit , anyway shops like **** smith or tandy stock the drive belts , take the front of the unit away from the main case there will be a plastic casing that surrounds the belts there are at least two belts, there should only be two small screws undo these and move the plastic unit forward on the plastic mounting brackets then you will see the metal wheel and the plastic wheel that you fit the belt around , its a bit fiddly but i can do it in my sleep now even though the motor died it was a good experience

Will my car stereo power 300 watt speakers?

it will power them but it will only push a small amount of wattage to them. something like 45 watts so they won't be very loud but if you run the wires you will hear them. It's beneficial to just invest in an amp you can pick up a 200 watt pretty cheap these days. and you will be much happier with the end result.

Jl audio 500/1 amp low ohm light at high volume

I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.
