these subs are a great buy for the price, the sound quality is great, I have it running off a 2 channel amp with 250 rms to each sub. the subs have a lot of punch and are still capable of reaching very low notes. definatly a great buy to b the loudest kid in the neihbourhood but not at a competition. I gave it a 4 because for the price and value its a lot of quality bass and durability. jbl stands up to there name in there line of competition subs. can def. give u a great massage but not capable of making u sick like my p1222's , great buy
Pros: functions great, lots of quality bass and excursion when powered properly! always give alteast 70% rms power to ure sub to prevent clipping and ruining ure subwoofers ppl! works great easy to wire and install.
Cons: not the strongest sub u can get on the market and these are sumwhat outdated but wrth the money.
