For those who have read my E46 stereo upgrade which consisted of some existing 6.5" coaxials (BA $ Infinity) and a Pioneer GM-X324 30WX4 amp, the following is a much better setup for not much more money.
I was looking forward replacing my aging speakers and
noticed many high quality ones are rated lower than 4 ohm nominal. The Pioneer amp is rated 30W/ch and 35W/ch
at 4ohm and 2ohm respectively. This means that this amp
can't supply enough current at lower impedance (hint: the power should double when the impedance is halved).
I also did not like the thumping noise heard when the
amp is turned on. So, it was time to return the amp and
found a better one. After some research I've decided to
try the new PPI amp from Precision Power model PPI4240.
The key factors in making this purchase was the company
reputation and its amp spec, although there is some skepticsm about the quality/perfomance of this new budget line.
The quality construction of this amp is first rate and
its sound is surprisingly superior to the Pioneer.
The biggest improvent was in the high frequency, butterly smooth and very detailed. The bass was also much stronger and cleaner and could be played louder
(PPI4240 [email protected] [email protected]).
The speakers to get are DEI HF3065 two way components
for the front and DEI HF2062 coaxial for the rear deck.
These are highly rated new line of speaker which I haven't gotten them yet (they're backordered).
My recommendation for budget audiophile stereo including mail order selling prices is:
Precision Power PPI4240 $209
DEI HF3065 6.5", 1" two-way $230
DEI HF2062 6.5" coaxial $100
typical amp installation $180
speaker installation (2set) $120
