	Yup thats correct. When the protect light comes on its usually a ground fault or a problem on the amplification side, such as incorrect impedence due to incorrect sub wiring, or a short on the subwoofer end.

	Could have been a dodgy earth or incorrect bridging.

	strugglin findin the amp........this is the same make as my gf's. My gf's is 1600w and has four channels. http://audiovisual.kelkoo.co.uk/sitesearch/go.jsp?offerId=3780723100314923uk3780723-RENEGADE-REN-800+Amplifier&orw This is her sub........no spec on here tho http://www.cheap-car-audio.co.uk/car-subwoofers-sony-12inch-sub-1200w-prod583.html?cheapaudio=bd8e3828a893978b0f65037c0f473a07

	im not too good with stuff like that and didnt understand a word of you post .lol. I'll post the spec up of the amp and sub in a sec mate

	looks fine to me. Is the amp bridgeable? Is the sub single or dual voice coil too? You might not be showing the amp the right impedence ofthe sub if it is DVC wired up wrong.

	My girlfriend had an amp n sub in her old corsa which I put in myself.........I then removed everythin the other day and put it in her new car.......it was in and playing for about 10 minutes then the amp just packed in (protect light came on), the headunit still plays fine tho. Luckily the guy who we bought the amp off is a friend so he is sendin it back as a demic and replacin ours but what could I have done wrong? This is what I did: 1. Wire from battery to power on amp (inc in-line fuse) 2. Earth lead from bolt on metal chassis to earth on amp 3. Phono leads from head unit into first two pre-outs on amp 4. Auto antenna from antenna lead on head unit to remote on amp 5. Sub wired into ported box then ports wired to plus on first channel and minus on the second channel? What could be wrong with the circuit as I dont want to fuck up another amp cos he probably wont change it again and was quite pricey to start with.
