Lights dim, deck cuts out

(first time posting bare with me)
OK, so i bought a 98 cavalier off my cousin, everthings fine with the car except for the sound system... now being a university student i didnt have a lot of money so i replaced the back two speakers with 2 pioneer 6x9s, now when i turn up the volume, and the bass hits the lights on the deck dim, and if i turn it up high enought the deck will cut out completely and shut off and then restart only to have the same thing happen again... Any suggestions... i know it will probably come up for a capacitor to be added, but i have no amp... i just removed the old speakers and wired up the new ones in their place... Thx for any help...

Hmm, what kind of deck do u have in it?

Just a sony xplod 50x4

Only thing i can thing of is there might be some wires crossed somewhere. and the reason why its shutting off is there is prolly a safety cut off built in.

you really shouldn't NEED a cap without a sub/amp setup....


check your speaker wiring...

are the front speakers stock?

Yes front speakers are still stock...

sounds to me that you are driving the deck too hard. Make sure you used the correct speakers 4 or 8 ohm. OR the power system is not strong enough to supply the power your deck needs to run. It is cutting out due to heat.
