sucks ***, if you are a moderate car audio fan like myself and wanna take the easy way out and not run new wires to your after market door speakers, think again. i have 4 rainbow entry level door coaxials running off this shitty mtx 2 channel amp, i had the wired from the amp (back of ccar) to the speaker wires up in the dash, just the stock ones, i did everything i could to get more out of these such as tweaking constantly etc.. the really sounded no better then the stock speakers untill today, i ran all new speaker wire and it was like day and night, shortening the wires by 4 feet each speaker at least, and with new wire. i had a bad prblem with them distorting at higher volume, now the dont, and get LOUDD. it made one hell of a difference. all the interference i had in the door speakers is gone, but not gone in the sub, im thinkin of buying one of the rca filters for it, but **** i wa surprised, this showed me to not always take the quick and easy way out
